【国外标准】 Standard Test Methods for Sampling and Testing Modified Bituminous Sheet Material

3.1 These test methods are used for sampling and testing modified bitumen sheet materials. Property requirements, determined by these test methods, are found in the following product standards: Specifications D6162/D6162M, D6163/D6163M, D6164/D6164M, D6222/D6222M, D6223/D6223M, D6298/D6298M, and D6509/D6509M.AbstractThese test methods cover procedures for sampling and testing prefabricated, reinforced, polymer-modified bituminous sheet materials designed for single- or multiple-ply application in roofing and waterproofing membranes. From each shipment or fraction thereof, select at random a number of rolls equal to one half the cube root of the total number of rolls in the lot. If the calculated number is fractional, express it as the next highest whole number. The load strain (tensile elongation and strain energy) properties shall be tested to meet the requirements prescribed. The tensile tear strength, moisture content, and water absorption of polymer-modified bituminous sheets shall be tested to meet the requirements prescribed. The dimensional stability, low-temperature flexibility, heat conditioning, and accelerated weathering of the polymer-modified bituminous sheets shall be tested to meet the requirements prescribed. The granule embedment, compound stability, coating thickness, low temperature unrolling, and precision and bias of the polymer-modified bituminous sheet materials shall be tested to meet the requirements prescribed.1.1 These test methods cover procedures for sampling and testing prefabricated, reinforced, polymer-modified bituminous sheet materials designed for single- or multiple-ply application in roofing and waterproofing membranes. These products may use various surfacing materials on one side.1.2 These test methods cover a number of different products. Not all tests are required for every product. Only those called out in the Product Standard are required.1.3 These test methods appear in the following order:  Section   Sampling  4Conditioning  5Thickness  6Load Strain Properties  7Tear Strength  8Moisture Content  9Water Absorption  10Dimensional Stability 11Low-Temperature Flexibility 12Heat Conditioning 13Accelerated Weathering 14Granule Embedment 15Compound Stability 16Coating Thickness 17Low Temperature Unrolling 18Precision and Bias 191.4 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.1.5 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.
