1.1 本试验方法旨在确定用热熔胶粘合的试样在静态剪切载荷下分层的温度。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1 热失效温度确定了一个极限温度，超过该温度时，粘合剂在剪切载荷下不会暴露在使用中。

1.1 This test method is intended to determine the temperature at which specimens bonded with hot melt adhesive delaminate under static load in shear. 1.2 The values stated in SI units are to be regarded as the standard. The values given 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 Heat-fail temperature establishes a limiting temperature above which the adhesive is not to be exposed in service under shear load.
