ASTM D7877-24(Guide)
Standard Guide for Electronic Methods for Detecting and Locating Leaks in Waterproof Membranes

SIGNIFICANCE AND USE
4.1 The failure to correct membrane defects during and as soon as possible after its installation can cause premature failure of the membrane. Problems include design deficiencies, faulty application of the membrane system, and damage by subsequent trades.4 Roof designs incorporating a waterproof membrane under overburden such as a vegetative roof, insulation layer, wear-course, or topping slab greatly exacerbate the problem of leak locating.  
4.2 This guide describes methods for using electric conductance testing to locate breaches in waterproof membranes.5 The methods described include testing procedures designed to provide a part of the construction quality control of membrane installations.  
4.3 The methods described in this guide may also be used for integrity or forensic testing of existing waterproof membranes; specific limitations apply.  
4.4 The electric conductance methods described in this guide require a conductive substrate under the membrane to serve as a ground return path for the test currents. In roof assemblies where the membrane is installed over electric insulating material such as insulating foam or a protection board, or both, the electric path to any conductive deck is interrupted. The situation can be remedied by placing a conductive material directly under the membrane. The conductive material provides the return path for the test currents.
SCOPE
1.1 This guide describes standard procedures for using electrical conductance measurement methods to locate leaks in exposed or covered waterproof membranes.  
1.2 This guide addresses the need for a general technical description of the current methods and procedures that are used to test and verify the integrity of waterproof membranes.  
1.3 This guide is not intended to replace visual, infrared, or other methods of inspection. It is to be used in conjunction with other methods of roof inspection when specified.  
1.4 This guide recommends that the leak location equipment, procedures, and survey parameters used are calibrated to meet established minimum leak detection sensitivity. The leak detection sensitivity calibration should be verified on a regular basis according to the manufacturer’s recommendations.  
1.5 Leak location surveys can be used on waterproofing membranes installed in roofs, plaza decks, pools, water features, covered reservoirs, and other waterproofing applications.  
1.6 The procedures are applicable for membranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, bituminous material, and other electrically insulating materials.  
1.7 This guide provides a general description of the equipment and methods for locating membrane breaches using electric conductance. Refer to the manufacturer’s instructions for the proper operation and use of the equipment described in this guide.  
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.

ASTM D6947/D6947M-16(2023)(Specification)
Standard Specification for Liquid Applied Moisture Cured Polyurethane Coating Used in Spray Polyurethane Foam Roofing System

ABSTRACT
This specification covers a single component protective roof coating composed of solvent-borne moisture curing urethane elastomeric polymer, to which various pigments or other additives have been added to give the required physical properties. The product, as manufactured, shall be in liquid form for application to spray polyurethane foam (SPF) surfaces by brushing, rolling, or spraying. However, guidance for its application is not addressed here. Coatings shall be tested and conform accordingly to specified liquid property requirements as to viscosity, and volume and weight of solids. Dry films shall also adhere to the following physical property requirements, when tested as appropriate: initial percent elongation at break; initial tensile strength at maximum stress; final percent elongation at break after accelerated weathering; permeance; water absorption; adhesion; fungi resistance; tear resistance; and low temperature flexibility.
SCOPE
1.1 This specification covers a single component, moisture cured, elastomeric urethane polymer coating used as a protective coating for spray polyurethane foam roofing systems.  
1.2 This specification does not provide guidance for application.  
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 nonconformance with the standard.  
1.4 The following precautionary caveat pertains only to the test method portions, Sections 5 and 6.  
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.

ASTM D7954/D7954M-22a(Practice)
Standard Practice for Moisture Surveying of Roofing and Waterproofing Systems Using Nondestructive Electrical Impedance Scanners

SIGNIFICANCE AND USE
5.1 Excess moisture trapped in roofing or waterproofing systems can adversely affect performance and lead to premature failure of roofing or waterproofing systems and its components. It also reduces thermal resistance, resulting in reduced energy efficiency and inflated energy costs. Impedance scans can be effective in identifying concealed and entrapped moisture within roofing or waterproofing systems.  
5.2 This practice is intended to be used at various stages of the roofing and waterproofing system’s life such as: during or at completion of installation of roofing or waterproofing system to determine if there was moisture intrusion into the roofing or waterproofing system or underlying materials; at regular intervals as part of a preventative maintenance program; and to aid in condition assessment, or before replacement or repair work, or combinations thereof, to assist in determining the extent of work and replacement materials.  
5.3 This practice alone does not determine the cause of moisture infiltration into roofing or waterproofing systems; however, it can be used to help tracing excess moisture to the point of ingress.
SCOPE
1.1 This practice applies to techniques that use nondestructive electrical impedance (EI) scanners to locate moisture and evaluate the comparative moisture content within insulated low-slope roofing and waterproofing systems.  
1.2 This practice is applicable to roofing and waterproofing systems wherein insulation is placed above the deck and positioned underneath and in contact with electrically nonconductive single-ply or built-up roofing and waterproofing membranes and systems such as coal tar, asphalt, modified bitumen, thermoplastics, spray polyurethane foam, and similar electrically nonconductive membrane materials. This practice is also applicable to roofing and waterproofing systems without insulation placed above moisture absorbing decks such as wood, concrete, or gypsum, that are in contact with single-ply or built-up roofing and waterproofing membranes as described above.  
1.3 This practice is applicable to roofing and waterproofing systems incorporating electrically nonconductive rigid board insulation made from materials such as organic fibers, perlite, cork, fiberglass, wood-fiber, polyisocyanurate, polystyrene, phenolic foam, composite boards, gypsum substrate boards, and other electrically nonconductive roofing and waterproofing systems such as spray-applied polyurethane foam.  
1.4 This practice is not appropriate for all combinations of materials used in roofing and waterproofing systems.  
1.4.1 Metal and other electrically conductive surface coverings and near-surface embedded metallic components are not suitable for surveying with impedance scanners because of the electrical conductivity of these materials.  
1.4.2 This practice is not appropriate for use with black EPDM, any membranes containing black EPDM, or black EPDM coatings because black EPDM gives false positive readings.  
1.4.3 Aluminum foil on top-faced insulation, roofing, or waterproofing membranes gives a false positive reading and is not suitable for surveying with impedance scanners; however, liquid-applied aluminum pigmented emulsified asphalt-based coatings shall not normally affect impedance scanner readings.
1.4.3.1 This practice is not appropriate for use with aluminium foil faced modified bitumen membranes, as the electrical conductivity of the aluminium foil surface can give false positive readings.  
1.4.4 While their overburden remains in place, this practice is not appropriate for use with inverted roof membrane assemblies (IRMAs) or protected roof assemblies (PRMAs), which contain above the deck waterproof membrane and overburden that may include insulation, drainage components, pavers, aggregate, ballast, vegetation, or combinations thereof, because the impedance scanner will not differentiate between above and below the membrane moisture.

ASTM C870-24(Practice)
Standard Practice for Conditioning of Thermal Insulating Materials

SIGNIFICANCE AND USE
5.1 The conditioning prescribed in this recommended practice is designed to obtain reproducible test results on thermal insulating materials. Results of tests obtained on these materials under uncontrolled atmospheric conditions are not comparable with each other. Some of the physical properties of thermal insulating materials are influenced by relative humidity and temperature in a manner that affects the results of tests. In this regard, such information is provided in pertinent material specifications and test methods by stating the physical properties relative to the specific ambient or test conditions.
Note 1: In some cases (for example, dimensionally unstable materials), the dry mass cannot easily be established and original mass has to be used.
SCOPE
1.1 This practice covers the conditioning of thermal insulating materials for tests. Since prior exposure of insulating materials to high or low humidity will affect the equilibrium moisture content, a procedure is also given for preconditioning the materials.  
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.

ASTM C390-08(2024)(Practice)
Standard Practice for Sampling and Acceptance of Thermal Insulation Lots

SIGNIFICANCE AND USE
4.1 The sampling and inspection prescribed in this practice afford the purchaser a practical level of quality assurance on incoming material. They are based on cost/risk relationships considered typical for preformed thermal insulations offered for general use. In all cases, the purchaser should review this practice and determine its suitability in terms of his specific needs.  
4.2 This procedure is intended primarily for the inspection of a continuing stream of lots, and there is not a high probability of rejecting occasional off lots. Consumer protection is based on economic pressure on the producer, through greater risk of lot rejection, to maintain the process average at 90 % conformance or better. Operating characteristic curves for the sampling plans employed can be found in Practice E2234, Table X-C through Table X-F.  
4.3 It is not the intent of this procedure to estimate lot quality, control the quality of production, relieve the supplier of responsibility for the quality of material offered, or determine the disposition of material found to be defective after receipt by the purchaser.
SCOPE
1.1 This practice covers criteria for establishing the acceptability of lots of shipments of preformed board, preformed block and pipe, and batts and blanket thermal insulation based on sampling and inspection.  
1.2 This practice is intended for use in conjunction with appropriate ASTM material specifications that classify and describe the specific physical requirements for the product in terms of qualification requirements and inspection requirements. Determination of nonconformity shall be based on the tolerances for individual sample test values prescribed in the material specification.  
1.3 This practice may require inspection substantially different from that performed in the normal course of production. If the purchaser requires sampling and acceptance inspection in accordance with this practice, he shall so specify in the order or contract.  
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.

Standard Specification for Polyimide Flexible Cellular Thermal and Sound Absorbing Insulation

ABSTRACT
This specification covers the composition and physical properties of lightweight, flexible open-cell polyimide foam insulation intended for use as thermal and sound-absorbing insulation for a certain temperature range in commercial and industrial environments. The insulations are classified into the following types: Types I, II, III, IV, V, and VI. Polyimide foam shall be manufactured from the appropriate monomers, and necessary compounding ingredients. Different test methods shall be performed in order to determine the following properties of the insulation: density, apparent thermal conductivity, upper temperature limit, high temperature stability, compressive strength, compression deflection, compression set, steam aging, corrosiveness, chemical resistance, surface burning characteristics, radiant panel surface flammability, vertical burn, heat release rate, specific optical smoke density, hydrogen halides in smoke, toxic gas generation, and sound absorption coefficients.
SCOPE
1.1 This specification covers the composition and physical properties of lightweight, flexible open-cell polyimide foam insulation intended for use as thermal and sound-absorbing insulation for temperatures from –328°F up to +572°F (–200°C and +300°C) in commercial and industrial environments.  
1.1.1 Annex A1 includes faced polyimide foam as specified by the U.S. Navy for marine applications.  
1.1.2 This standard is designed as a material specification and not a design document. Physical property requirements vary by application and temperature.
