1.1 本规范涵盖了用于粘接金属和非金属材料的两部分改性环氧糊状胶粘剂。当暴露在预期的应力、温度和相对湿度组合下时，粘合剂应适合形成能够承受-184至82°C[-300至180°F]温度的环境暴露的粘合剂。 注1: 经国防部（DoD）和美国国家航空航天局（NASA）协调后，该实践将直接取代MIL-a-82720（OS）、MIS-26872和MSFC-SPEC-2037。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。在文本中，英寸-磅单位显示在括号中。每个系统中规定的值不是精确的等价物；因此，每个系统必须相互独立使用。合并两个系统的值可能会导致不符合本规范。 1.3 以下预防说明仅适用于试验方法部分，第 8. ，本规范: 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。

1.1 The specification covers a two-part modified epoxy paste adhesive for bonding metallic and nonmetallic materials. The adhesive should be suitable for forming bonds that can withstand environmental exposure to temperatures from –184 to 82 °C [–300 to 180 °F] when exposed to an expected combination of stress, temperature, and relative humidity to be encountered in service. Note 1: When coordinated through the Department of Defense (DoD) and the National Aeronautics and Space Administration (NASA), this practice will be a direct replacement of MIL-A-82720 (OS), MIS-26872, and MSFC-SPEC-2037. 1.2 The values stated in SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification. 1.3 The following precautionary statement pertains to the test method portion only, Section 8 , 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, 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.
