ASTM E1111/E1111M-14(2022)(Test Method)
Standard Test Method for Measuring the Interzone Attenuation of Open Office Components

SIGNIFICANCE AND USE
5.1 Providing speech privacy in open-plan spaces depends upon many factors, the most significant of which are the following:  (1) the shadow zone of part-height space dividers and the diffraction of sound from the edges of space dividers; (2) the primary sound reflective properties of the ceiling system; (3) the level of masking sound present in the space; and (4) the distance between speaker and listener. Guide E1374 provides additional detail on the factors contributing to speech privacy in open-plan spaces.  
5.2 In this test method the third factor, masking sound, is eliminated and the fourth factor, the distance between speaker and listener, is standardized for all specimen types. For the measurement of ceiling systems, the first factor, the shadow zone, is also standardized for each divider height used. Experience has indicated that results obtained by this test method may not fairly represent the speech privacy that may be achievable with non-flat ceiling systems. For the measurement of furniture panels used as acoustical barriers, the second of these factors, the sound reflectance of the ceiling, is standardized. For the measurement of reflective and absorptive vertical surfaces used as wall finishings or furniture panels, the first and second factors are standardized and all paths between the speaker and listener reflecting only off of the ceiling are eliminated.  
5.3 This test method provides standardized techniques to assess the contribution of specific components of an open-plan space. The test method specifies an acoustical testing environment for each component type that isolates its contribution from the contribution of other components, which may in actual open-plan environments contribute significantly to the overall speech privacy.  
5.4 The significance of test results obtained by this test method must also be considered with regard to the attainable measurement accuracy. The attainment of speech privacy in the presence of masking sound is cri...
SCOPE
1.1 This test method covers the measurement of the interzone attenuation for three components of open-plan spaces:  
1.1.1 Ceiling systems when used in conjunction with partial-height space dividers. This arrangement is commonly used in offices to achieve speech privacy between work zones in the absence of full-height partitions. This test method is applicable to any ceiling configuration, including, for example, a pattern of sound-reflective panels in an otherwise sound-absorptive ceiling. This test method generally requires use of a fixed space divider height of 1.50 m [5 ft]. In recognition of trends toward alternate divider heights in open office environments, measurements with an alternate divider height may be conducted in accordance with this standard.  
1.1.2 Furniture panels used as acoustical barriers in open-plan spaces to provide speech privacy or sound isolation between working positions.  
1.1.3 Vertical panels, including wall finishes such as sound-absorbent panels, and furniture panels or screens which may reflect sound. It may not be applicable to such items as window finishes or furniture other than panels if these differ significantly from flat wall panels.  
1.1.4 The combination of results from the various components of an open-plan office is beyond the scope of this standard.  
1.2 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.  
1.3 Unless otherwise qualified, all dimensions specified in this test method shall be understood to have a tolerance of ±6 mm (±1/4 in.) The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

ASTM E580/E580M-22(Practice)
Standard Practice for Installation of Ceiling Suspension Systems for Acoustical Tile and Lay-in Panels in Areas Subject to Earthquake Ground Motions

ABSTRACT
This practice covers acoustical ceiling suspension systems and their additional requirements for application in areas subject to light to moderate seismic disturbance such as Uniform Building Code Seismic Zone 2, the BOCA Basic National Building Code where Av is less than 0.20 but greater than 0.10, and the Standard Building Code (SBC) where Av is less than 0.20 but greater than 0.05. This practice also covers areas subject to moderate to severe seismic disturbance such as Uniform Building Code Seismic Zones 3 and 4, the BOCA Basic National Building Code where Av is greater than 0.20, and the SBC where Av is greater than 0.20. The application of this practice is to be determined by local authorities. Current seismic maps published by recognized authorities such as those previously mentioned, as well as related material such as Open File 82-1033 and MS-812 Seismicity Maps, should be consulted. This practice is not intended to stifle research and development of new products or methods which may simplify the application method specified herein. A variation, however, must be substantiated by verifiable engineering data. A ceiling area of 144 ft2 [13m2] or less, surrounded by walls that connect directly to the structure above shall be exempt from this practice.
SIGNIFICANCE AND USE
3.1 This practice is a prescriptive set of installation methods to be used for suspended ceilings and is often used in lieu of designing a separate lateral restraint system. The authority having jurisdiction shall determine the applicability of this practice to local code requirements.  
3.2 This practice covers installation of suspended ceiling systems and related components in areas that require resistance to the effects of earthquake motions as defined by ASCE 7 and the International Building Code.  
3.3 The practice is broken into two main sections. The first section covers areas with light to moderate earthquake potential (Seismic Design Category C) while the second deals with severe earthquake potential (Seismic Design Category D, E & F).  
3.4 This practice includes requirements from multiple sources including previous versions of this practice, CISCA Seismic Recommendations for Direct-hung Acoustical Tile and Lay-in Ceilings, Seismic Zones 0-2 and CISCA Guidelines for Seismic Restraint for Direct Hung Suspended Ceiling Assemblies, Seismic Zones 3 & 4, suspended ceiling requirements from the International Building Code and ASCE 7. The purpose is to combine the requirements from these sources into a single comprehensive document.
SCOPE
1.1 This practice covers the installation of suspended systems for acoustical tile and lay-in panels and their additional requirements for two groups of buildings that are constructed to resist the effects of earthquake motions as defined by ASCE 7 and the International Building Code. These groupings are for Seismic Design Category C and Seismic Design Categories D, E and F.  
1.2 The authority having jurisdiction shall determine the applicability of this practice.  
1.3 Test Methods E3090/E3090M, Specification C635, and Practice C636 cover suspension systems, their installation, and testing without special regard to seismic lateral restraint needs. They remain applicable and shall be followed when this practice is specified.  
1.4 Ceilings less than or equal to 144 ft2 [13.4 m2] and surrounded by walls connected to the structure above are exempt from the requirements of this practice.  
1.5 This practice is not intended to stifle research and development of new products or methods. This practice is not intended to prevent the installation of any material or prohibit any design or method of construction not prescribed in this practice, provided that any such alternative has been substantiated by verifiable engineering data or full-scale dynamic testing that is acceptable to the authority having jurisdiction.  
1.6 Ceiling areas of 1000 ft2 [92.9 m2] or less shall be exempt from the...

Standard Classification for Determination of Single-Number Metrics for Impact Noise

SIGNIFICANCE AND USE
4.1 The rating increases as the impact sound attenuation of the floor ceiling structure increases. The rating can be used by architects, builders, and specification and code authorities for acoustical design purposes in building constructions.  
4.2 The rating strictly only applies to excitation by the standard tapping machine defined in Test Methods E492 and E1007. It does not deal with low frequency sounds below 100 Hz that are typically generated below lightweight joist floors when they are walked on. Nor does it deal with the squeaking, crunching or rattling sounds that can occur in joist construction when elements in the construction are loose and occupants walk on the floor.  
4.3 This classification shall only be used with one-third octave band data.
SCOPE
1.1 This classification provides a method for determining a rating that can be used to compare the levels of impact noise generated by a standard tapping machine and transmitted through different floor-ceiling assemblies.  
1.2 The name given to the rating is assigned by the test method that invokes this classification.  
1.3 This classification is applicable only to one third octave band impact noise data obtained using the standard tapping machine described in Test Methods E492 and E1007.  
1.4 Test methods that invoke this classification include:  
1.4.1 Test Method E492 – the single-number rating is called impact insulation class (IIC).  
1.4.2 Test Method E1007 – the single-number ratings are called apparent impact insulation class (AIIC), impact sound rating (ISR), and normalized impact sound rating (NISR).  
1.4.3 Test Method E2179 – the single-number rating is called the change in impact insulation class (ΔIIC).  
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 Measurement of pH Below Resilient Flooring Installations

SIGNIFICANCE AND USE
4.1 There is typically a higher concentration of soluble alkali salts in the surface region of a concrete slab due to the initial bleeding process of a freshly placed concrete slab. If after a resilient floor covering material is installed there is sufficient moisture within the slab to place these salts into solution a potentially damaging high pH solution can develop beneath the installed material.  
4.2 Results obtained through the use of this guide indicate the comparative pH of reagent water placed on properly prepared concrete slab surfaces only at the time of the procedure and in the specific locations evaluated.  
4.3 If pre-installation surface pH evaluation is required by the manufacturer of the resilient flooring, adhesive, patching/underlayment products or project specifications, their instructions and limitations should be consulted.
SCOPE
1.1 This guide discusses procedures that may be used for evaluating the comparative change in pH of reagent water placed on the surface of a properly prepared concrete slab surface.  
1.2 This guide is intended to be used in conjunction with the flat surface electrode pH meter manufacturer’s calibration procedures, operation instructions, and interpretive data where available.  
1.3 This guide is intended to be used in conjunction with the pH paper manufacturer’s instructions, product shelf life, and interpretive data where available.  
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 Some specific hazards statements are given in Section 9 on Hazards.  
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.

ASTM F1869-23(Test Method)
Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride

SIGNIFICANCE AND USE
4.1 Use this test method to obtain a quantitative value indicating the rate of moisture vapor emission from the surface of a concrete floor and whether or not that floor is acceptable to receive resilient floor covering. The moisture vapor emission rate only reflects the condition of the concrete floor at the time of the test. All concrete subfloors emit some amount of moisture in vapor form. Concrete moisture emission is a natural process driven by environmental conditions. All floor coverings are susceptible to failure from excessive moisture vapor emissions. The moisture vapor emitted from a concrete slab is measured in pounds. This measurement is the equivalent weight of water evaporating from 1000 ft2 of concrete surface in a 24-h period. The calcium chloride moisture test has been the industry standard for making this determination and is a practical, well-established and accepted test of dynamic moisture. It will produce quantified results directly applicable to flooring manufacturer's specifications. The results obtained reflect the condition of the concrete floor surface at the time of testing and may not indicate future conditions.
SCOPE
1.1 This test method covers the quantitative determination of the rate of moisture vapor emitted from below-grade, on-grade, and above-grade (suspended) bare concrete floors.  
1.2 This test shall not be used to evaluate the rate of moisture vapor emitted by gypsum concrete or floors containing lightweight aggregate.  
1.3 This test shall not be used to evaluate moisture vapor emissions over coatings on concrete or through reactive penetrants or over patching or leveling compounds.  
1.4 This quantity of moisture shall be expressed as the rate of moisture vapor emission, measured in pounds of moisture over a 1000 ft2 area during a 24-h period.  
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.

Standard Classification for Acoustical Ceiling Products

SIGNIFICANCE AND USE
4.1 This classification is used to classify and aid in the selection of acoustical ceiling products.
SCOPE
1.1 This classification covers ceiling products that provide acoustical performance and interior finish in buildings. Products used in performance spaces and other special applications in some cases require more detailed specification than provided by this classification.  
1.2 This classification classifies acoustical ceilings by type, pattern, and certain ratings for acoustical performance, light reflectance, and fire safety. It does not cover the aspects of acoustical ceilings when used as a component of a system or assembly tested for fire endurance or floor/ceiling sound transmission.  
1.3 This classification does not include physical properties, such as structural hardness, friability, sag, linear expansion and contraction, and transverse strength, which affect the handling, installation, and use of acoustical ceiling products (see Test Methods C367).  
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 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 Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter

SIGNIFICANCE AND USE
5.1 Moisture in concrete floor slabs affects the performance of flooring systems such as resilient, wood, and textile floor coverings and coatings. Manufacturers of such systems generally require moisture testing be performed before installation of coverings on floor slabs and screeds. The measurement of sub-surface comparative moisture condition in the upper 1.0 in. (25.4 mm) stratum of a concrete slab with a non-destructive moisture meter is one such method.  
5.2 Excessive moisture in floor slabs after installation can cause floor covering system failures such as delamination, bonding failure, deterioration of finish flooring and coatings, and microbial growth.  
5.3 5.3 Comparative moisture content tests indicate the moisture in the slab, which is usually referenced to the percentage of dry weight. That is:
Results indicate conditions at the time of the test.  
5.4 Methods of meter calibration and factors affecting equilibration are described in Section 8.
SCOPE
1.1 This guide focuses on obtaining the comparative moisture condition within the upper 1.0 in. (25.4 mm) stratum in concrete, gypsum, anhydrite floor slabs and screeds for field tests. Due to the wide variation of material mixtures and additives used in floor slabs and screeds, this methodology may not be appropriate for all applications. See 1.2 through 1.8 and Section 11. Where appropriate or when specified, use further testing as outlined in Test Methods F1869 or F2170 before installing a resilient floor covering.  
1.2 This guide is intended for use to determine if there are moisture-related conditions existing on, or in, the floor slabs that could adversely impact the successful application and performance of resilient flooring products.  
1.3 This guide may be used to aid in the diagnosis of failures of installed resilient flooring.  
1.4 This guide is intended to be used in conjunction with meter manufacturer’s operation instructions and interpretive data where available.  
1.5 Where possible or when results need to be quantified, use this guide to determine where additional testing such as Test Methods F1869 or F2170 as specified to characterize the floor slab and the test area environment for moisture, humidity and temperature conditions.  
1.6 This guide may not be suitable for areas that have surface applied moisture migration systems, curing compounds or coatings that cannot be removed or cleaned off sufficiently to allow the moisture to move upwards through the slab. For a floor slab of 6 in. (150 mm) plus thickness, low porosity slabs, slabs with no vapor retarder installed, and slabs where the above surface environmental conditions can have a greater than normal influence on the moisture reduction gradient of the floor slab or screed, consider Test Method F2170 (below surface in situ rh method) as a more suitable test method under these circumstances.  
1.7 This guide is not intended to provide quantitative results as a basis for acceptance of a floor for installation of moisture sensitive flooring finishes systems. Test Methods F1869 or F2170 provide quantitative information for determining if moisture levels are within specific limits. Results from this guide do not provide vital information when evaluating thick slabs, slabs without effective vapor retarders directly under the slab, lightweight aggregate concrete floors, and slabs with curing compound or sealers on the surface.  
1.8 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.  
1.9 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...
