Standard Test Method for Determining Air Leakage Rate of Air Barrier Assemblies

Standard Test Method for Determining Air Leakage Rate of Air Barrier Assemblies

SIGNIFICANCE AND USE
5.1 This method is intended to simulate the performance of various air barrier materials/accessories when combined into an assembly. Based upon the results of the measurements, this procedure then assigns an air leakage rating for the air barrier assembly.  
5.2 This method does not purport to establish all criteria necessary for consideration in the selection of an air barrier assembly. The results are intended to be used for comparison purposes and may not represent the field installed performance of the air barrier assembly when installed as part of an air barrier system in a building. However, the results of these tests may be useful in determining the appropriate use of a specified air barrier system assembly.  
5.3 This method does not purport to establish all criteria necessary for air barrier systems of all construction types. Test Method E2178 provides an air permeance test method for testing of some air barrier materials. Specification E1677 provides a specification for air barrier systems for low-rise framed building walls.
SCOPE
1.1 This test method covers the determination of the air leakage rate of air barrier assemblies that are used in building enclosures. This procedure measures the air leakage of a representative air barrier assembly before and after exposure to specific conditioning cycles and then assigns a rating dependent upon the results. Although this is a laboratory procedure, the method may also be applied to site mockups.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Characterization and Use of Hygrothermal Models for Moisture Control Design in Building Envelopes

SIGNIFICANCE AND USE
4.1 This guide is intended to provide the framework for characterizing the functions of the hygrothermal model and the level of sophistication used as inputs for each analysis. Hygrothermal modeling has become an important practice in support of the decision-making design processes involved in moisture management of building envelope systems. Increasingly, hygrothermal models are an integral part of building envelope performance assessment, retrofit, and restoration studies and provide insight in the screening of alternative design approaches affecting water management of the envelope system. Hygrothermal models are used in decision making during the design process of building envelope systems. They may also be used to assess performance of the envelopes of existing buildings, or to predict envelope performance in buildings undergoing retrofit, change in use, restoration or flood remediation. It is, therefore, important to have a methodology to document the model used in a hygrothermal investigation. This documentation provides needed characterization of the hygrothermal model to assess its credibility and suitability. This becomes even more important because of the increasing complexity of the building envelope systems for which new hygrothermal models are being developed. There are many different hygrothermal models available, each with specific capabilities, operational characteristics, and limitations. If modeling is considered for a project, it is important to determine if a hygrothermal model is appropriate for that project, or if a model exists that can perform the simulations required in the project.  
4.2 Quality assurance in a hygrothermal analysis using modeling is achieved by using the most appropriate model with all important transport mechanisms, initial conditions, and boundary conditions. A well-executed quality assurance program in hygrothermal modeling requires systematic and complete documentation of the model and the inputs followed by consisten...
SCOPE
1.1 This guide offers guidance for the characterization and use of hygrothermal models for moisture control design of building envelopes. In this context, “hygrothermal models” refers to the application of a mathematical model to the solution of a specific heat and moisture flow performance issue or problem. Hygrothermal models are used to predict and evaluate design considerations for the short-term and long-term thermal and moisture performance of building envelopes.  
1.2 Each hygrothermal model has specific capabilities and limitations. Determining the most appropriate hygrothermal model for a particular application requires a thorough analysis of the problem at hand, understanding the required transport processes involved, and available resources to conduct the analysis. Users of this guide can describe the functionality of the hygrothermal model used in an analysis in a consistent manner.  
1.3 This guide applies to hygrothermal models that range from complex research tools to simple design tools. This guide provides a protocol for matching the analysis needs and the capabilities of candidate models.  
1.4 This guide applies to the use of models that include all or part of the following thermal and moisture storage and transport phenomena: (1) heat storage of dry and wet building materials, (2) heat transport by moisture-dependent thermal conduction, (3) phase change phenomena (for example, evaporation and condensation), (4) heat transport by air convection, (5) moisture retention by vapor adsorption and capillary forces, (6) moisture transport by vapor diffusion (molecular and effusion), (7) moisture transport by liquid transport (surface diffusion and capillary flow), and (8) moisture (vapor) transport by air convection.  
1.5 This guide does not apply to cases requiring analysis of the following: (1) convection that occurs in a three-dimensional manner or through holes and cracks; (2) hydraulic, osmotic, or ...

ASTM E1423-21(Practice)
Standard Practice for Determining Steady State Thermal Transmittance of Fenestration Systems

SIGNIFICANCE AND USE
4.1 This practice details the test specimen sizes and test conditions, namely, the room-side and weather-side air temperatures, and the surface heat transfer coefficients for both sides of the test specimen, when testing fenestration products in accordance with Test Method C1199.  
4.2 The thermal transmittance and conductance of a specimen are affected by its size and three-dimensional geometry. Tests should therefore be conducted using the specimen sizes recommended in 5.1. Should the specimen size differ from those given in 5.1, the actual size shall be reported in the test report.  
4.3 Many factors can affect the thermal performance of a fenestration system, including deflections of sealed glazing units. Care should be exercised to maintain the original physical condition of the fenestration system and while installing it in the surround panel.  
4.4 The thermal transmittance and conductance results obtained do not, and are not intended, to reflect performances expected from field installations since they do not account for solar radiation and air leakage effects. The thermal transmittance and conductance results are taken from specified laboratory conditions and are to be used only for fenestration product comparisons and as input to thermal performance analyses that also include solar and air leakage effects.
SCOPE
1.1 This practice covers standard test specimen sizes and test conditions as well as the calculation and presentation of the thermal transmittance and conductance data measured in accordance with Test Method C1199. The standard sizes and conditions are to be used for fenestration product comparison purposes. The specifier may choose other sizes and conditions for product development or research purposes.  
1.2 This practice deals with the determination of the thermal properties of a fenestration system installed vertically without the influences of solar heat gain and air leakage effects.
Note 1: To determine air leakage effects of fenestration systems, Test Method E283/E283M or E1424 should be referenced.
Note 2: See Appendix X1 regarding garage doors and rolling doors.  
1.3 This practice specifies the procedure for determining the standardized thermal transmittance of a fenestration test specimen using specified values of the room-side and weather-side surface heat transfer coefficients, hh and hc, respectively.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Evaluation and Rehabilitation of Mass Masonry Walls for Changes to Thermal and Moisture Properties of the Wall

SIGNIFICANCE AND USE
4.1 Energy conservation is being addressed more often on existing and historically significant buildings constructed with solid exterior mass masonry walls. Without proper evaluation, changes to the thermal and moisture properties of the exterior walls could have serious negative impacts on the existing masonry, new or existing wall components, and building operations.  
4.2 A thorough understanding of the original construction and subsequent alterations, condition of materials, properties, initial moisture content, water and air leakage potential, and building operations are necessary before undertaking the addition of interior insulation, air barrier, vapor retarder, or other changes to thermal or vapor resistance of the wall.  
4.3 Degradation of the existing masonry along with moisture related problematic conditions and indoor air quality issues could develop if alterations are undertaken in an improper manner to the exterior wall assembly.
SCOPE
1.1 This guide addresses the evaluation of existing mass masonry walls for the potential addition of interior insulation and continuous air barrier or vapor retarder or other changes to the thermal and moisture management properties of the wall.  
1.2 This guide describes methods for evaluating moisture accumulation related problems specific to mass masonry walls. This guide does not apply to walls that include provisions to manage bulk water through internal drainage, flashings, or other measures other than the moisture storage capacity of the wall.  
1.3 This guide describes analysis, design, and specification of materials with the required thermal, air, and vapor resistance to improve the energy performance of an existing mass masonry wall, but that would not create problematic conditions to the masonry units or within the masonry wall or interior of the building.  
1.4 This guide applies to walls of masonry construction meeting the requirements of a “mass masonry wall” as defined herein. This guide does not apply to masonry walls that, by design, are intended to manage water as a barrier wall system or drainage wall system.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E283/E283M-19(Test Method)
Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Skylights, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen

SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining the air leakage characteristics under specified air pressure differences at ambient conditions.
Note 2: The air pressure differences acting across a building envelope vary greatly. The factors affecting air pressure differences and the implications or the resulting air leakage relative to the environment within buildings are discussed in the literature.4-6 These factors should be fully considered in specifying the test pressure differences to be used.  
5.2 Rates of air leakage are sometimes used for comparison purposes. Such comparisons may not be valid unless the components being tested and compared are of essentially the same size, configuration, and design.
SCOPE
1.1 This test method covers a standard laboratory procedure for determining the air leakage rates of exterior windows, skylights, curtain walls, and doors under specified differential pressure conditions across the specimen. The test method described is for tests with constant temperature and humidity across the specimen. Persons interested in performing air leakage tests on units exposed to various temperature differences across the specimen should reference Test Method E1424.  
1.2 This laboratory procedure is applicable to exterior windows, skylights, curtain walls, and doors and is intended to measure only such leakage associated with the assembly and not the installation. The test method can be adapted for the latter purpose.  
Note 1: Performing tests under uncontrolled conditions or with a temperature differential across the specimen may affect the air leakage rate. This is not addressed by this test method.  
1.3 This test method is intended for laboratory use. Persons interested in performing field air leakage tests on installed units should reference Test Method E783.  
1.4 Persons interested in evaluating air permeance of building materials should reference Test Method E2178.  
1.5 Persons interested in determining air leakage of air barrier assemblies should reference Test Method E2357.  
1.6 Persons using this procedure should be knowledgeable in the areas of fluid mechanics, instrumentation practices, and shall have a general understanding of fenestration products and components.  
1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.8 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statement, see Section 7.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Measuring the Air Leakage Rate of a Large or Multizone Building

SIGNIFICANCE AND USE
5.1 This test method does not establish requirements for airtightness but provides means of assessing compliance with specified air-leakage rates established elsewhere.  
5.2 This test method is used to determine the airtightness of building envelopes or portions thereof by measuring the air leakage rate at specified reference pressure differentials.  
5.3 This test method provides:  
5.3.1 Specific directions for determining acceptable weather conditions for conducting the test.  
5.3.2 Two different test boundary preparation conditions; building envelope (9.1.1.1), and operational envelope (9.1.1.2).  
5.3.3 Testing conducted in a range of pressures from 10 Pa (0.04 in. WC) to 100 Pa (0.40 in. WC).  
5.4 A measurement of the air-leakage rate of the constructed building envelope. Test methods that measure the air permeance of materials (Test Method E2178) and air leakage of assemblies (Test Method E2357) alone do not address the various complexities of the constructed building envelope, including but not limited to design, sequence, constructability, workmanship, and the transitions between assemblies.  
5.5 This test method applies to all multizone and large building types and portions or subsections of buildings. It can be used to test envelopes that consist of a single zone or subsections of a zone that can be tested as a single zone. Test envelopes that are entirely composed of subsections separated by interior partitions or floors, or both, may be tested as a single zone by maintaining baseline relationships between these subsections throughout testing. (See Appendix X1. See also Test Methods E779 and E1827.) Isolated subsections, each with its own specified air-leakage rate, shall be treated as separate test envelopes and tested separately. While testing isolated subsections, monitoring must be conducted for any extraneous/flanking air movement between the different zones.  
5.6 The building preparations prior to testing (fenestration positions and pr...
SCOPE
1.1 This standard test method provides a quantitative field-test procedure and calculation method for assessing an air leakage rate using a fan-induced pressure differential(s) across the building envelope, generated by blower doors or equivalent equipment.  
1.2 Building setup conditions in accordance with defining the test boundaries appropriate for testing the envelope’s air leakage are defined in this test method.  
1.3 Procedure to determine the air pressure boundaries of the test envelope to be tested are provided in this test method.  
1.4 This test method applies to all multizone and large building types and portions or subsections thereof.  
1.5 This test method defines three test procedures: multipoint regression, repeated single point, and repeated two-point air leakage rate testing.  
1.6 This test method allows for testing the test envelope in a pressurized condition, a depressurized condition, or in both conditions and averaging the results.  
1.7 This test method applies to an air leakage rate specification with a reference pressure greater than 10 Pa (0.04 in. WC) and not greater than 100 Pa (0.40 in. WC).  
1.8 This test method describes two methods of preparation for the building in order to conduct the test: the building envelope where HVAC-related openings are excluded, and on the operational envelope where the HVAC-related openings are included.  
1.9 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The test environment is intended to simulate conditions that have been observed and defined in full-scale attic experiments.  
5.2 The test is intended to be suitable for regulatory statutes, specification acceptance, design purposes, or development and research.  
5.3 The fundamental assumption inherent in the test is that critical radiant flux is one measure of the surface burning characteristics of exposed insulation on floors or between joists of attics.  
5.4 The test is applicable to attic floor insulation specimens that follow or simulate accepted installation practice.  
5.5 In this procedure, the specimens are subjected to one or more specific sets of laboratory fire test exposure conditions. If different test conditions are substituted or the anticipated end-use conditions are changed, caution should be used to predict changes in the performance characteristics measured by or from this test. Therefore, the results are strictly valid only for the fire test exposure conditions described in this procedure.  
5.5.1 If the test results obtained by this test method are to be considered in the total assessment of fire hazard in a building structure, then all pertinent established criteria for fire hazard assessment developed by Committee E-5 must be included in the consideration.
SCOPE
1.1 This fire-test-response standard describes a procedure for measuring the critical radiant flux of exposed attic floor insulation subjected to a flaming ignition source in a graded radiant heat energy environment in a test chamber. The specimen is any attic floor insulation. This test method is not applicable to those insulations that melt or shrink away when exposed to the radiant heat energy environment or the pilot burner.  
1.2 This fire-test-response standard measures the critical radiant flux at the point at which the flame advances the farthest. It provides a basis for estimating one aspect of fire exposure behavior for exposed attic floor insulation. The imposed radiant flux simulates the thermal radiation levels likely to impinge on the floors of attics whose upper surfaces are heated by the sun through the roof or by flames from an incidental fire in the attic. This fire-test-response standard was developed to simulate an important fire exposure component of fires that develop in attics, but is not intended for use in estimating flame spread behavior of insulation installed other than on the attic floor.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.4 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this standard.  
1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardizatio...

Standard Practice for Determination of Thermal Resistance of Attic Insulation Systems Under Simulated Winter Conditions

SIGNIFICANCE AND USE
4.1 The thermal resistance of a ceiling system is used to characterize its steady-state thermal performance.  
4.2 The thermal resistance of insulation is related to the density and thickness of the insulation. Test data on thermal resistance are obtained at a thickness and density representative of the end use applications. In addition, the thermal resistance of the insulation system will be different from that of the thermal insulation alone because of the system construction and materials.  
4.3 This practice is needed because the in-service thermal resistance of some permeable attic insulations under winter conditions is different, lower or higher R, than that measured at or close to simulated room temperature conditions utilizing small-scale tests in which the insulation is sandwiched between two isothermal impermeable plates that have a temperature difference (ΔT) of 20 to 30°C [36 to 54°F]. When such insulation is installed in an attic, on top of a ceiling composed of normal building materials such as gypsum board or plywood, with an open top surface exposed to the attic air space, the thermal resistance under winter conditions with heat flow up and large temperature differences is significantly less because of additional heat transfer by natural convection. Fig. 1 illustrates the difference between results from small scale tests and tests under the conditions of this practice. See Ref (1-12) for discussions of this phenomenon.3
FIG. 1 Schematic of Thermal Resistance for a Permeable Attic Insulation Under Simulated Winter Conditions (Heat Flow Up)
Note 1: A constant hot-side temperature (T, hot) is used for both tests and the temperature difference increases as the cold side temperature (T, cold) is decreased. See 5.1.6 for requirements on size of air space.  
4.4 In normal use, the thickness of insulation products ranges from 75 mm [3 in.] to 500 mm [20 in.]. Installed densities will depend upon the product type, the installed thickness, the installa...
SCOPE
1.1 This practice presents a laboratory procedure to determine the thermal resistance of attic insulation systems under simulated steady-state winter conditions. The practice applies only to attic insulation systems that face an open attic air space.  
1.2 The thermal resistance of the insulation is inferred from calculations based on measurements on a ceiling system consisting of components consistent with the system being studied. For example, such a system might consist of a gypsum board or plywood ceiling, wood ceiling joists, and attic insulation with its top exposed to an open air space. The temperature applied to the gypsum board or plywood shall be in the range of 18 to 24°C [64 to 75°F]. The air temperature above the insulation shall correspond to winter conditions and ranges from –46°C to 10°C [–51 to 50°F]. The gypsum board or plywood ceiling shall be sealed to prevent direct airflow between the warm and cold sides of the system.  
1.3 This practice applies to a wide variety of loose-fill or blanket thermal insulation products including fibrous glass, rock/slag wool, or cellulosic fiber materials; granular types including vermiculite and perlite; pelletized products; and any other insulation material that is installed pneumatically or poured in place. The practice considers the effects on heat transfer of structures, specifically the ceiling joists, substrate, for example, gypsum board, air films, and possible facings, films, or other materials that are used in conjunction with the insulation.  
1.4 This practice measures the thermal resistance of the attic/ceiling system in which the insulation material has been preconditioned according to the material Specifications C549, C665, C739, and C764.  
1.5 The specimen preparation techniques outlined in this standard do not cover the characterization of loose-fill materials intended for enclosed applications.  
1.6 This practice is be used to characterize mate...

Standard Practice for Determination of Thermal Resistance of Pneumatically Installed Loose-Fill Building Insulation (Behind Netting) for Enclosed Applications of the Building Thermal Envelope

SIGNIFICANCE AND USE
4.1 The thermal resistance, R, of an insulation is used to describe its thermal performance.  
4.2 The thermal resistance of an insulation is related to the density and thickness of the insulation. It is desirable to obtain test data on thermal resistances at thicknesses and densities related to the end uses of the product.  
4.3 In normal use, the thickness of these products range from less than 100 mm (4 in.) to greater than 150 mm (6 in.). Installed densities depend upon the product type, the installed thickness, the installation equipment used, the installation techniques, and the geometry of the insulated space.  
4.4 Loose-fill insulations provide coverage information using densities selected by manufacturers to represent the product installed densities. Generally, it is necessary to know the product thermal performance at a representative density.  
4.5 When applicable specifications or codes do not specify the nominal thermal resistance level to be used for comparison purposes, a recommended practice is to use the Rsi (metric) = 2.65 m F/Btu]) label density and thickness for that measurement.  
4.6 If the density for test purposes is not available from the coverage chart, a test density shall be established by use of applicable specifications and codes or, if none apply, agreement between the requesting body and the testing organization.  
4.7 Generally, thin sections of these materials are not uniform. Thus, the test thickness must be greater than or equal to the product’s representative thickness if the results are to be consistent and typical of use.
Note 1: The representative thickness is specific for each product and is determined by running a series of tests in which the density is held constant but the thickness is increased. The representative thickness is defined here as that thickness above which there is no more than a 2 % change in the resistivity of the product. The representative thickness is a function of product blown density. In gene...
SCOPE
1.1 This practice presents a laboratory guide to determine the thermal resistance of pneumatically installed loose-fill building insulations for enclosed applications of the building thermal envelope behind netting at mean temperatures between –10 and 35°C (14 to 95°F).  
1.2 This practice applies to a wide variety of loose-fill thermal insulation products including but not limited to fibrous glass, rock/slag wool, or cellulosic fiber materials and any other insulation material that can be installed pneumatically. It does not apply to products that change their character after installation either by chemical reaction or the application of binders, adhesives or other materials that are not used in the sample preparation described in this practice, nor does it consider the effects of structures, containments, facings, or air films.  
1.3 Since this practice is designed for reproducible product comparison, it measures the thermal resistance of an insulation material which has been preconditioned to a relatively dry state. Consideration of changes of thermal performance of a hygroscopic insulation by sorption of water is beyond the scope of this practice.  
1.4 The sample preparation techniques outlined in this practice do not cover the characterization of loose-fill materials intended for open applications and not intended for spray-applied applications.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in t...

Standard Guide for Readily Observable Moisture Affected Materials and Conditions Conducive to Elevated Moisture in Commercial Buildings: Limited Moisture Assessment Process

SIGNIFICANCE AND USE
4.1 Use—This guide is intended for use on a voluntary basis by parties who wish to obtain a limited survey of commercial real estate to assess for readily observable moisture affected materials and physical deficiencies conducive to elevated moisture as part of a commercial real estate transaction or commercial property management. This guide is intended to constitute a limited inquiry using representative observations for the purposes of conducting due diligence regarding the actual and potential presence of readily observable moisture affected materials and physical deficiencies conducive to elevated moisture in connection with the subject property. Inquiries that are more and less comprehensive than this guide (including, in some instances, no inquiry) may be appropriate in some circumstances in the opinion of the user (for example, when the presence of moisture affected materials is known to the user). Furthermore, no implication is intended that a person must use this guide in order to be deemed to have conducted appropriate inquiry in a commercially prudent or reasonable manner in a particular transaction. Nevertheless, this guide is intended to reflect a commercially prudent and reasonable inquiry. However, a LMA is not intended to serve as a comprehensive survey for the presence of readily observable moisture affected materials and physical deficiencies conducive to elevated moisture in all or most of the building systems throughout a commercial building.  
4.2 Clarification of Use:  
4.2.1 Specific Point in Time—Because conditions conducive to elevated moisture in a building can vary greatly over time due to changes in weather, interior air handling and conditioning, occupancy, and so forth, a user should only rely on the results presented in the report for the point in time at which the LMA was conducted.  
4.2.2 Site-Specific—This guide is site-specific in that it relates to assessment of readily observable moisture affected materials and physical def...
SCOPE
1.1 Purpose—The purpose of this guide2 is to define good commercial practice for conducting a limited survey for readily observable moisture affected materials and conditions conducive to elevated moisture in a commercial building related to commercial real estate transaction or commercial real estate management by conducting: a walk-through survey, document reviews, and interviews as outlined within this guide. This guide is intended to provide a practical means for the limited identification of moisture affected materials and physical deficiencies conducive to elevated moisture caused by water infiltration through the building envelope or substructure or generated within the subject building as a result of processes or mechanical systems, excluding de minimis conditions. This guide is to allow a user to assess general moisture concerns, as well as the potential need for further assessment or other actions that may be appropriate that are beyond the scope of this guide. For purposes of this guide, the initialism “LMA” or “Limited Moisture Assessment” is used interchangeably with this guide’s full title.  
1.2 Purpose Limitations—While a LMA may be used to survey for readily identifiable moisture affected materials and physical deficiencies conducive to elevated moisture, the LMA is not designed to serve as comprehensive survey for the presence of moisture affected materials and physical deficiencies conducive to elevated moisture in all or most areas in a commercial building. It is not intended to reduce or eliminate the risks that elevated moisture may pose to the subject building or its occupants.  
1.3 Considerations Beyond This Scope—The use of this guide is limited to the scope set forth in this section. Section 12 of this guide identifies, for informational purposes, certain physical conditions (not an all-inclusive list) that may exist at a subject property and certain activities or procedures (not an all-inclu...

Standard Test Method for Determination of Installed Thickness of Pneumatically Applied Loose-Fill Building Insulation

SIGNIFICANCE AND USE
5.1 This test method was designed to give the manufacturer of loose-fill insulation products a way of determining what the initial installed thickness should be in a horizontal open attic for pneumatic applications.  
5.2 The installed thickness value developed by this test method is intended to provide guidance to the installer in order to achieve a minimum mass/unit area for a given R-value.  
5.3 For the purpose of product design, testing should be done at a variety of R-values. At least three R-values should be used: the lowest R-value on the product label, the highest R-value on the product label, and an R-value near the midpoint of the R-value range.
Note 1: For quality control purposes, testing may be done at one R-value of R-19 (h×ft 2×°F/Btu) or higher.  
5.4 Specimens are blown in a manner consistent with the intended installation procedure. Blowing machine settings should be representative of those typically used for field application with that machine.  
5.5 The material blown for a given R-value as part of the installed thickness test equals the installed mass/unit area times the test chamber area. This mass can be calculated from information provided on the package label at the R-value prescribed.
SCOPE
1.1 This test method covers determination of the installed thickness of pneumatically applied loose-fill building insulations prior to settling by simulating an open attic with horizontal blown applications.  
1.2 This test method is a laboratory procedure for use by manufacturers of loose-fill insulation for product design, label development, and quality control testing. The apparatus used produces installed thickness results at a given mass/unit area.  
1.3 This test method is not the same as the design density procedures described in Test Methods C520 or Specifications C739 or C764.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
