Respiratory Protection -
Powered Air-purifying Respirator
1 Scope
This standard specifies the classification, labelling, technical requirements, test methods
and identification of powered air-purifying respirators.
This standard is applicable to powered air-purifying respirators preventing particles, toxic
and harmful gas or vapor.
This standard is not applicable to respirators used in combustible, explosive and
oxygen-deficient environment and for escaping.
