1.1 本规范涵盖了在无障碍盥洗室和水槽下的外露排水管和供水管道上使用的绝缘盖。绝缘盖应具有隔热性能，以保护残疾人免受烧伤和身体伤害，避免其接触无障碍盥洗室和水槽下暴露的供水和废水管道。绝缘盖应可拆卸且可重复使用。 1.2 包括厕所和水槽下外露排水管和供水管道上可拆卸和可重复使用保护盖的分类标准，以及材料和工艺的要求和测试方法。给出了标记方法。 1.3 本规范涵盖的产品仅用于盥洗室和水槽下的供水和排水或废水管道。 1.4 以英寸-磅为单位的数值应视为标准值。 括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.5 本规范未建立使用可拆卸绝缘盖的设备设计所需的标准，也未建立或建议可拆卸绝缘盖在所有表面的适用性。 1.6 本标准不适用于盥洗室和水槽下的护罩。 1.7 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。 1.8 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 This specification covers insulating covers for use on exposed drain and water supply piping under accessible lavatories and sinks. The insulating covers shall have thermal insulating properties to protect people with disabilities from burns and physical harm from contact with exposed water supply and waste piping under accessible lavatories and sinks. Insulating covers shall be removable and reusable. 1.2 Included are criteria for classifying removable and reusable protective covers on exposed drain and water supply piping under lavatories and sinks and requirements and test methods for materials and workmanship. Methods of marking are also given. 1.3 The products covered by this specification are intended for use on water supply and drain or waste piping under lavatories and sinks only. 1.4 The values stated in inch-pound units shall be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This specification does not establish the criteria required in the design of the equipment over which removable insulating covers are used, nor does this specification establish or recommend the applicability of removable insulating covers over all surfaces. 1.6 This standard does not apply to shrouds under lavatories and sinks. 1.7 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. 1.8 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.
