动力送风过滤式呼吸器的标准化

Powered Air-Purifying Respirator Standardization

本文结合动力送风呼吸器国家标准的制订工作,概述了该国家标准的编制背景、原则,对该类呼吸防护装备的分类、主要技术内容及其编制依据,如送风量、泄漏率、防护时间、有效气流量等进行了介绍。该国家标准的制定对于规范和指导我国动力送风过滤式呼吸器的发展以及推动其应用具有重要的意义。

According to the national standard development of powered air-purifying respirator, an overview of the background and principle for the standardization, the classification of this type respiratory protective device, the main technical characteristics, together with the determination basis for the key factors, such as air supply, inward leakage, protective time, and interactive flow rate et al. is introduced. This mandatory national standard will specific and guide the development of such respiratory protective equipment, at the same time it will significantly promote its application.
