4.1 This practice is used to outline the minimum necessary elements and conditions to obtain an accurate determination of the location of wet insulation in roofing systems using infrared imaging.4.2 This practice is not meant to be an instructional document or to provide all the knowledge and background necessary to provide an accurate analysis. For further information, see ANSI-ASHRAE Standard 101 and ISO/DP 6781.3E.4.3 This practice does not provide methods to determine the cause of moisture or its point of entry. It does not address the suitability of any particular system to function capably as waterproofing.1.1 This practice applies to techniques that employ infrared imaging at night to determine the location of wet insulation in roofing systems that have insulation above the deck in contact with the waterproofing. This practice includes ground-based and aerial inspections. (Warning—Extreme caution shall be taken when accessing or walking on roof surfaces and when operating aircraft at low altitudes, especially at night.) (Warning—It is a good safety practice for at least two people to be present on the roof surface at all times when ground-based inspections are being conducted.)1.2 This practice addresses criteria for infrared equipment such as minimum resolvable temperature difference, spectral range, instantaneous field of view, and field of view.1.3 This practice addresses meteorological conditions under which infrared inspections shall be performed.1.4 This practice addresses the effect of roof construction, material differences, and roof conditions on infrared inspections.1.5 This practice addresses operating procedures, operator qualifications, and operating practices.1.6 This practice also addresses verification of infrared data using invasive test methods.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. Specific precautionary statements are given in 1.1.1.9 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.

This specification covers woven cotton fabrics saturated with either asphalt or coal-tar intended for use with asphalt based plying cement (such as mopping asphalts or appropriate solvent bearing asphaltic compounds), coal-tar based plying cement (such as coal-tar pitch or other appropriate solvent bearing coal-tar compounds), or appropriate solvent bearing bituminous materials in the construction of roofing and waterproofing systems. The dry cotton fabric shall be thoroughly and uniformly saturated with bitumen by passing the fabric through the saturant or by spraying with saturant, calendering in the presence of heat, and then cooling before winding on a core. Products shall be sampled, tested, and adhere accordingly to specified physical (breaking load in both the warp and fill directions, and pliability), and dimensional (mass, width, thread count, moisture, and ash content) property requirements. The finished product shall not crack nor be so sticky as to cause tearing or other damage upon being unrolled at a given temperature.1.1 This specification covers woven cotton fabrics saturated with either asphalt or coal-tar pitch intended to be used with asphalts conforming to Specifications D312/D312M or D449/D449M, coal-tar pitches conforming to Specification D450/D450M, or appropriate solvent bearing bituminous materials in the construction of roofing and waterproofing systems.1.1.1 Asphalt-saturated cotton fabric shall be used with asphalt base plying cement; typical ones are mopping asphalts conforming to Specifications D312/D312M or D449/D449M or appropriate solvent bearing asphaltic compounds.1.1.2 Coal-tar-saturated cotton fabric shall be used with coal-tar based plying cements; a typical one is coal-tar pitch conforming to Specification D450/D450M or appropriate solvent bearing coal-tar compounds.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 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.

This specification covers fiber or fabric reinforced nonvulcanized white polymeric sheet made from polyisobutylene (PIB) intended for use as a single-ply roof membrane exposed to the weather. In-place roof systems design criteria such as fire resistance, field seaming strength, impact/puncture resistance, material compatibility, and uplift resistance, among others, are beyond the scope of this specification. Backed sheets shall conform to the following physical properties: thickness; breaking strength; elongation; tearing strength; low temperature bend; linear dimensional change; fabric adhesion; hydrostatic resistance; ozone resistance; and weather resistance. On the other hand, coating portions on the weather side of the sheet containing no backing shall adhere to the following physical properties: tensile strength; elongation; tear resistance; ozone resistance; and water absorption.1.1 This specification covers white reinforced non-vulcanized polymeric sheet made from polyisobutylene (PIB) intended for use as a single-ply roof membrane exposed to the weather. The sheet shall be reinforced with fiber or fabric.1.1.1 The polymers used in these sheets have thermoplastic characteristics at time of installation.1.2 The tests and property limits used to characterize these sheets are minimum values.1.2.1 In-place roof systems design criteria such as fire resistance, field seaming strength, impact/puncture resistance, material compatibility, and uplift resistance, among others, are factors that must be considered, but are beyond the scope of this specification.The following precautionary caveat pertains to the test methods portion only, Section , of this specification: 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 and health practices and determine the applicability of regulatory requirements prior to use.

3.1 This test method is used to determine the quality of adhesion of the granular surfacing to the coating asphalt in a sample of mineral-surfaced roofing. The results determine compliance with the applicable specification requirements or for comparative analysis. This test method applies to “as manufactured” material and may not be applicable to material that has had weathering exposure.1.1 This test method covers the determination of granule adhesion to mineral-surfaced roofing due to abrasion.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 nonconformance 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.
