This document specifies minimum requirements for particle filtering half masks as respiratory protective devices intended to protect the wearer in occupational settings, where there is a health risk(s) from inhaling any type of particles during working activities except for escape purposes.

Laboratory and practical performance tests or references to test method standards are included for the assessment of compliance with the requirements.

This document specifies the technical requirements and the necessary tests of Excess Flow Device (EFD) for use with respiratory protective devices (RPD), up to 300 bar operating pressure. Devices that only close the flow in the event of a valve break-off do not fall within the scope of this document. NOTE Throughout the breathing apparatus market exists a variety of cylinder valves that can have different ways of connecting to an EFD. The interchangeability of the EFD is only possible in the case of verified combinations of cylinder valve and EFD. The use of unverified combinations is not considered safe.
