BS 8547:2016规定了潜水员的最低性能要求 用于开路和饱和气体的便携式呼吸气体需求调节器 回收用于潜水深度超过50米的系统。本英国标准规定了呼吸性能的附加要求 以及与BS EN 250中已经给出的氦相容性和 英国标准EN 15333-1。注意潜水设备和需求调节器的基本要求，参见 保留了EN-250和EN-1531。这里的例外是 本英国标准对呼吸性能进行了修订，以涵盖 在深度大于50 m的地方使用的要求。本英国标准规定了氦与空气相容性的试验方法 需求调节器和测量呼吸功的试验方法 （WOB）和需求调节器的呼吸压力。本英国标准不包括辅助紧急呼吸系统；他们 见BS EN 250:2014附录B。交叉引用: BS EN 132BS EN 250:2014BS EN 12021BS EN 15333-1:2008购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS 8547:2016 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.Cross References:BS EN 132BS EN 250:2014BS EN 12021BS EN 15333-1:2008All current amendments available at time of purchase are included with the purchase of this document.
