Requirements and test methods Ingestion-build-46800 but makes reference to theseWhat is this standard about? The efficiency of breathing demand regulators is fundamental to the safe use of many types of underwater breathing apparatus. However until now, no standard covered demand regulators in self contained diving apparatus to depths greater than 50 metres; or demand regulators in umbilical supplied apparatus beyond 60 metres. Given that deeper dives now take place more frequently, BS 8547 was written to meet the clear need for
