Respiratory equipment. Breathing gas demand regulator used for diving to depths greater than 50 metres. Requirements and test methodsWhat 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.
