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.
