1.1 本试验方法涵盖了SBS（苯乙烯-丁二烯-苯乙烯）改性沥青板与工厂应用的金属箔表面的循环热暴露引起的移动测量。 1.2 以国际单位制表示的数值应视为标准值。括号中的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本试验方法用于确定暴露于规定循环热条件下产品的尺寸变化和物理稳定性。它在确定金属箔和SBS之间的粘结完整性方面也很有用- 改性沥青化合物。

1.1 This test method covers the measurement of movement due to cyclic thermal exposure of SBS (styrene-butadiene-styrene)-modified bituminous sheets with a factory-applied metal foil surface. 1.2 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only. 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. ====== Significance And Use ====== 4.1 This test method is used to determine the dimensional changes and physical stability of the product upon exposure to specified cyclic thermal conditions. It is also useful in determining the integrity of the bond between the metal foil and the SBS-modified bituminous compound.
