1 Scope This standard specifies the classification and designation, technical requirements, mask testing methods, filter testing method, inspection rules and marking of non-powered air-purifying respirators. This standard is applicable to the respirators based on the non-powered air-purifying principle. This standard is not applicable to the respiratory protection equipment used in the anoxygenous environment, underwater operation, escape process and fire-fighting hotspot. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, the parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards.
