Standard Practice for Repair of a Rigid Cellular Polyurethane Insulation System on Outdoor Service Vessels

Standard Practice for Repair of a Rigid Cellular Polyurethane Insulation System on Outdoor Service Vessels

ABSTRACT
This practice covers the repair of rigid cellular polyurethane insulation systems on outdoor service vessels operating within a specified temperature range. Before any repairs are performed, all damaged nonadhering foam should be removed up to the dry, solidly adhering layer and the remaining foam insulation should then be beveled on all sides. If the existing substrate primer is damaged, it should be wire-brushed and reprimed where feasible. To protect the surrounding undamaged area, a covering should be installed around the area that needs to be repaired prior to the application of spray foam. Repairs shall be made in accordance with the prescribed procedure.
SCOPE
1.1 This practice covers the repair of spray-applied polyurethane insulation on vessels normally operating at temperatures between −30 and +107°C [−22 and +225°F].  
1.2 Warning—At temperatures below 0°C [32°F] the application of a spray “foam” directly onto the cold substrate may not be possible. The term “foam” applies to spray-applied polyurethane or polyisocyanurate (PUR or PIR) rigid cellular plastic only, and not to any other plastic insulation.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 This standard may involve hazardous materials, operations, and equipment. 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.  For a specific precautionary statement see 1.2.  
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 Test Method for Predicting Long-Term Thermal Resistance of Closed-Cell Foam Insulation

SIGNIFICANCE AND USE
5.1 Rigid gas-filled closed-cell foam insulations include all cellular plastic insulations which rely on a blowing agent (or gas), other than air, for thermal resistance values. At the time of manufacture, the cells of the foam usually contain their highest percentage of blowing agent and the lowest percentage of atmospheric gases. As time passes, the relative concentrations of these gases change due primarily to diffusion. This results in a general reduction of the thermal resistance of the foam due to an increase in the thermal conductivity of the resultant cell gas mixture. These phenomena are typically referred to as foam aging.  
5.1.1 For some rigid gas-filled closed-cell foam insulation products produced using blowing agent gases that diffuse very rapidly out of the full-thickness foam product, such as expanded polystyrene, there is no need to accelerate the aging process.  
5.1.2 Physical gas diffusion phenomena occur in three dimensions. The one-dimensional form of the diffusion equations used in the development of this practice are valid only for planar geometries, that is, for specimens that have parallel faces and where the thickness is much smaller than the width and much smaller than the length.  
Note 3: Please see Appendix X3 for a discussion of the theory of accelerated aging via thin slicing.
Note 4: Theoretical and experimental evaluations of the aging of insulation in radial forms, such as pipe insulation, have been made. (6) However, these practices have not evolved to the point of inclusion in the test standard.  
5.2 The change in thermal resistance due to the phenomena described in 5.1 usually occurs over an extended period of time. Information regarding changes in the thermal resistance of these materials as a function of time is required in a shorter period of time so that decisions regarding formulations, production, and comparisons with other materials can be made.  
5.3 Specifications C578, C591, C1029, C1126 and C1289 on rigid cl...
SCOPE
1.1 This test method covers a procedure for predicting the long-term thermal resistance (LTTR) of unfaced or permeably faced rigid gas-filled closed-cell foam insulations by reducing the specimen thickness to accelerate aging under controlled laboratory conditions (1-5) .2
Note 1: See Terminology, 3.2.1, for the meaning of the word aging within this standard.  
1.2 Rigid gas-filled closed-cell foam insulation includes all cellular plastic insulations manufactured with the intent to retain a blowing agent other than air.  
1.3 This test method is limited to unfaced or permeably faced, homogeneous materials. This method is applied to a wide range of rigid closed-cell foam insulation types, including but not limited to: extruded polystyrene, polyurethane, polyisocyanurate, and phenolic. This test method does not apply to impermeably faced rigid closed-cell foams or to rigid closed-cell bun stock foams.
Note 2: See Note 8 for more details regarding the applicability of this test method to rigid closed-cell bun stock foams.  
1.4 This test method utilizes referenced standard test procedures for measuring thermal resistance. Periodic measurements are performed on specimens to observe the effects of aging. Specimens of reduced thickness (that is, thin slices) are used to shorten the time required for these observations. The results of these measurements are used to predict the long-term thermal resistance of the material.  
1.5 The test method is given in two parts. The Prescriptive Method in Part A provides long-term thermal resistance values on a consistent basis that can be used for a variety of purposes, including product evaluation, specifications, or product comparisons. The Research Method in part B provides a general relationship between thermal conductivity, age, and product thickness.  
1.5.1 To use the Prescriptive Method, the date of manufacture must be known, which usually involves the cooperation of the m...

(1) Substrate preparation,  
(2) Substrate priming,  
(3) Insulation application, and  
(4) Protective coatings.  
4.2 Abrasive blasting, primer application, spray application of the insulation, and protective coating application each contribute their unique health and safety hazards to the job site and will be dealt with in more detail under their respective headings.
SCOPE
1.1 This practice concerns itself with the substrate preparation and priming, the selection of the rigid cellular polyurethane system, and the protective insulation coatings for outdoor service equipment.  
Note 1: For the purpose of this practice, polyurethane is defined to mean either polyurethane or polyisocyanurate and is hereafter referred to as “PUR/PIR.”  
1.2 The values given in inch-pound are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 This standard may involve hazardous materials, operations, and equipment. 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 Specification for Preformed Flexible Elastomeric Cellular Thermal Insulation in Sheet and Tubular Form

ABSTRACT
This specification covers sheet and tubular preformed flexible elastomeric cellular thermal insulation. The materials are classified into three grades according to the operating temperature range of the industrial systems that each material is used for. The non-thermoplastic, thermoset products should be made of natural or synthetic rubber that may be modified using various thermoplastic or thermosetting resins, plasticizers, modifiers, antioxidants, curatives, blowing agents, and other additives. All products should be tested using the prescribed procedures and conform to the specified values of apparent thermal conductivity, water absorption, water-vapor permeability, and linear shrinkage.
SCOPE
1.1 This specification covers preformed flexible elastomeric cellular-thermal insulation in sheet and tubular form. Grade 1 covers materials to be used on commercial or industrial systems with operating temperatures from –183 to 104°C [–297 to 220°F], Grade 2 covers material used on industrial systems with operating temperatures from –183 to 150°C [–297 to 300°F], and Grade 3 covers material used on industrial systems with operating temperatures from –183 to 120°C [–297 to 250°F] where halogens are not permitted.  
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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 Specification for Unfaced Preformed Rigid Cellular Polyisocyanurate Thermal Insulation

ABSTRACT
This specification covers the types, physical properties, and dimensions of unfaced, preformed rigid cellular polyurethane modified polyisocyanurate plastic material intended for use as thermal insulation on surfaces. This insulation can be classified into six types according to its compressive resistance: Types I, IV, II, III, V, and VI. Also this insulation can be classified as Grades 1 and 2 according to its service temperature range. The thermal insulation is produced by the polymerization of polymeric polyisocyanates in the presence of polyhydroxyl compounds, catalysts, cell stabilizers, and blowing agents. Different test methods shall be performed in order to determine the thermal insulation's following properties: density, compressive resistance, apparent thermal conductivity, hot-surface performance, water absorption, water vapor permeability, dimensional stability, closed-cell content, surface bearing characteristics, tensile strength, and leachable chloride, fluoride, silicate, and sodium ions.
SCOPE
1.1 This specification covers the types, physical properties, and dimensions of unfaced, preformed rigid cellular polyisocyanurate plastic material intended for use as thermal insulation on surfaces from –297°F (–183°C) to 300°F (149°C). For specific applications, the actual temperature limits shall be agreed upon by the manufacturer and purchaser.  
1.2 This specification only covers “polyurethane modified polyisocyanurate” thermal insulation which is commonly referred to as “polyisocyanurate” thermal insulation. This standard does not encompass all polyurethane modified materials. Polyurethane modified polyisocyanurate and other polyurethane materials are similar, but the materials will perform differently under some service conditions.  
1.3 This standard is designed as a material specification, not a design document. Physical property requirements vary by application and temperature. At temperatures below –70°F (–51°C) the physical properties of the polyisocyanurate insulation at the service temperature are of particular importance. Below –70°F (–51°C) the manufacturer and the purchaser must agree on what additional cold temperature performance properties are required to determine if the material can function adequately for the particular application.  
1.4 This standard addresses requirements of unfaced preformed rigid cellular polyisocyanurate thermal insulation manufactured using blowing agents with an ozone depletion potential of 0 (ODP 0).  
1.5 Except 6.2 and 8.2 – 8.4, which are related to the size and shape of fabricated parts, and 16.1, which is related to the storage of fabricated parts, the requirements in this standard specification apply to the polyisocyanurate insulation in the form of buns supplied by the insulation manufacturer.  
1.6 When adopted by an authority having jurisdiction, codes that address fire properties in many applications regulate the use of the thermal insulation materials covered by this specification. Fire properties are controlled by job, project, or other specifications where codes or government regulations do not apply.  
1.7 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.  
1.8 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.  
1.9 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.

SIGNIFICANCE AND USE
5.1 This test method is designed to produce tensile property data for material specifications, research and development, quality assurance, and structural design and analysis. Factors that influence the tensile response and should be reported include the following: material, methods of material preparation and lay-up, specimen stacking sequence, specimen preparation, specimen conditioning, environment of testing, specimen alignment and gripping, speed of testing, time at temperature, and volume percent reinforcement. Properties, in the test direction, which may be obtained from this test method include the following:  
5.1.1 Ultimate tensile strength,  
5.1.2 Ultimate tensile strain,  
5.1.3 Tensile modulus of elasticity, and  
5.1.4 Poissons ratio.
SCOPE
1.1 This test method covers the determination of the tensile properties of metal matrix composites reinforced by continuous and discontinuous high-modulus fibers. Nontraditional metal matrix composites as stated in 1.1.6 also are covered in this test method. This test method applies to specimens loaded in a uniaxial manner tested in laboratory air at either room temperature or elevated temperatures. The types of metal matrix composites covered are:  
1.1.1 Unidirectional laminates (all fibers aligned in a single direction) containing either continuous or discontinuous reinforcing fibers. Both longitudinal and transverse properties may be obtained.  
1.1.2 0°/90° balanced crossply laminates containing either continuous or discontinuous reinforcing fibers.  
1.1.3 Angleply laminates containing continuous reinforcing fibers, with layups that do not include 0° reinforcing fibers (that is, (±45)ns, (±30)ns, and so forth).  
1.1.4 Multidirectional laminates containing continuous reinforcing fibers, with layups including 0° reinforcing fibers (that is, (0/±45/90)ns quasi-isotropic laminates, (0/±30)ns laminates, and so forth).  
1.1.5 Laminates containing unoriented and random discontinuous fibers.  
1.1.6 Directionally solidified eutectic composites.  
1.2 The technical content of this standard has been stable since 1996 without significant objection from its stakeholders. As there is limited technical support for the maintenance of this standard, changes since that date have been limited to items required to retain consistency with other ASTM D30 Committee standards. The standard therefore should not be considered to include any significant changes in approach and practice since 1996. Future maintenance of the standard will only be in response to specific requests and performed only as technical support allows.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.  
1.4 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.  
1.5 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 Test Method for Polyurethane Raw Materials: Determination of Basicity in Polyols, Expressed as Percent Nitrogen

SIGNIFICANCE AND USE
5.1 This test method is suitable for quality control, as a specification test, and for research. The results are measures of batch-to-batch uniformity and are useful in estimating reactivity.  
5.1.1 The percent nitrogen can be used to characterize a polyol or indicate amounts of certain components in a polyol blend.  
5.1.2 It is permissible to also express the results in equivalents of base per gram of sample, if desired.
SCOPE
1.1 This test method measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0.3 % to 10 % nitrogen have been evaluated by this method. This test method is applicable to polyether polyols and polyether polyol blends that are used in urethane reactions. (See Note 1.)  
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.
Note 1: This standard is equivalent to ISO 25761:08.  
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.
