1.1 本规范涉及用于环境温度连续高达1400°F（760°C）的表面的分层玻璃纤维毡管和板隔热材料。 1.2 用于制造该产品的玻璃纤维有时被称为E-玻璃纤维。 1.3 制造过程中没有添加饰面，本规范也没有涉及。 1.4 这种材料是一种高温工业隔热材料，通常覆盖有现场安装的保护套。但是，本规范中未涉及护套材料。 1.5 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 1.6 以下安全隐患警告仅适用于本规范中描述的测试方法。本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。 本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification addresses layered, glass fiber felt pipe and board insulation for use on surfaces with temperatures from ambient up to 1400°F (760°C) continuous. 1.2 Glass fibers used to make this product are sometimes referred to as E-glass fibers. 1.3 Facings are not added in the manufacturing process and are not addressed by this specification. 1.4 This material is a high temperature, industrial thermal insulation that is typically covered with field-installed protective jacketing. However, jacketing materials are not addressed in this specification. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 The following safety hazards caveat pertains only to the test methods described in 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. 1.7 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.
