BS 8547:2016


This standard BS 8547:2016 Respiratory equipment. Breathing gas demand regulator used for diving to depths greater than 50 metres. Requirements and test methods is classified in these ICS categories:
  • 13.340.30 Respiratory protective devices

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 50 m.

This British Standard defines additional requirements for breathing performance and helium compatibility to those already given in BS EN 250 and BS EN 15333‑1.

NOTE The basic requirements for diving apparatus and demand regulators as per BS EN 250 and BS EN 15333‑1 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 50 m.

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 BS EN 250:2014, Annex B.
