1.1 本规范涵盖在高于或低于环境温度以及室内和室外位置运行的隔热、隔音和防火隔热不锈钢护套。它不包括由其他材料制成的绝缘护套，如胶泥、纤维增强塑料、PVC、铝或涂层碳钢（例如，铝锌、镀锌钢或镀铝钢），也不包括隔热、隔音或防火绝缘系统的细节。 1.2 虽然本标准不涵盖核电站安全壳厂房内的使用，但不排除在该安全壳厂房应用中使用无防潮层的E类材料。 1.3 本规范规定了隔热和隔音不锈钢护套的物理要求。 指导 C1423 为护套材料的选择及其安全使用提供指导。 1.4 这是材料规范，并不意味着使用本文规定的材料安装的系统的任何性能。有关不锈钢护套安装的信息，请参阅 ( 1. ) . 2. 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 注1: 本规范的IP单位版本可作为规范提供 C1767 . 1.6 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。

1.1 This specification covers stainless steel jacketing for thermal, acoustical, and fire protective insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. It does not cover insulation jacketing made from other materials such as mastics, fiber reinforced plastic, PVC, aluminum, or coated carbon steel (for example, aluminum-zinc, galvanized steel, or aluminized steel) nor does it cover the details of thermal, acoustical, or fire protective insulation systems. 1.2 While not intended to cover use inside the containment buildings of nuclear power plants, this standard does not preclude use of Class E material which does not have a moisture barrier in this containment building application. 1.3 This specification provides physical requirements for stainless steel jacketing for thermal and acoustical insulation. Guide C1423 provides guidance in selecting jacketing materials and their safe use. 1.4 This is a material specification and does not imply any performance of the installed system using the materials specified herein. For information about installation of stainless steel jacketing, see ( 1 ) . 2 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 1: A version of this specification in IP units is available as Specification C1767 . 1.6 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.
