1.1 本规范涵盖了无需进入/重新进入即可立即紧急疏散的空气净化呼吸防护排烟装置的设计、性能、测试和认证的最低要求。 1.2 本规范的目的是为呼吸防护逃生装置提供最低要求，该装置为火灾副产品（包括颗粒物、一氧化碳、其他有毒气体和辐射热的影响）的逃生提供15分钟的有限保护。 1.3 本规范的要求规定了一种空气净化呼吸防护逃生装置，其使用寿命经过实验室测试为15分钟，旨在为头部、眼睛和呼吸系统提供保护，使其免受颗粒物、刺激物以及火灾通常产生的有毒气体和蒸汽的侵害。 1.4 用于确定是否符合本规范性能要求的受控实验室测试不应被视为为确定个人可能接触的所有情况的性能水平。 1.5 本规范不适用于空气净化呼吸防护排烟装置的提供、安装或使用要求。 1.6 本规范不适用于在存在或可能存在缺氧（氧气体积分数低于19.5%）的情况下使用的呼吸防护逃生装置。 1.7 本规范不打算用作详细的制造或采购规范，但应允许在采购规范中作为最低要求引用。 1.8 指南的合格评定要求 F3050 C型应适用于符合本规范的产品认证。 1.9 单位-- 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.10 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。 1.11 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 covers the minimum requirements for the design, performance, testing, and certification of air-purifying respiratory protective smoke escape devices for immediate emergency evacuation without entry/re-entry. 1.2 The purpose of this specification shall be to provide minimum requirements for respiratory protective escape devices that provide limited protection for 15 min for escape from the by-products of fire, including particulate matter, carbon monoxide, other toxic gases, and the effects of radiant heat. 1.3 The requirements of this specification specify an air-purifying respiratory protective escape device with a laboratory-tested 15-min service life intended to provide head, eye, and respiratory protection from particulate matter, irritants, and toxic gases and vapors commonly produced by fire. 1.4 Controlled laboratory tests that are used to determine compliance with the performance requirements of this specification shall not be deemed as establishing performance levels for all situations to which individuals can be exposed. 1.5 This specification shall not apply to the requirements for provision, installation, or use of air-purifying respiratory protective smoke escape devices. 1.6 This specification shall not apply to respiratory protective escape devices intended for use in circumstances in which an oxygen deficiency (oxygen less than 19.5 % by volume) exists or might exist. 1.7 This specification is not intended to be used as a detailed manufacturing or purchase specification, but shall be permitted to be referenced as a minimum requirement in purchase specifications. 1.8 The conformity assessment requirements of Guide F3050 , Model C, shall apply to the certification of products in accordance with this specification. 1.9 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.10 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. 1.11 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.
