Annex A (informative) - Gas density and gas mixtures

Describes minimum performance requirements for diver carried breathing gas demand regulators for open-circuit and saturation gas reclaim systems used for diving to depths greater than 50 m.

This British Standard specifies minimum performance requirements for diver carried breathing gas demand regulators for open-circuit and saturation gas reclaim systems used for diving to depths greater than 50m.

This British Standard defines additional requirements for breathing performance and helium compatibility to those already given in BSEN250 and BSEN15333‑1.

NOTE The basic requirements for diving apparatus and demand regulators as per BSEN250 and BSEN15333‑1 have been retained. The exception here is for the breathing performance which is revised in this British Standard to cover the requirement for use at depths greater than 50m.

This British Standard specifies a test method for helium compatibility with a demand regulator and a test method for measuring the work of breathing (WOB) and respiratory pressures of a demand regulator.

This British Standard does not cover auxiliary emergency breathing systems; they are covered in BSEN250:2014, Annex B.
