What is BS EN 14593‑1-Requirements, testing, and marking for compressed airline breathing devices with demand valves about?
BS EN 14593 discusses requirements for compressed airline breathing devices with demand valves in respiratory protective devices (RPD). BS EN 14593‑1 is a European standard that provides requirements, testing, and marking for compressed airline breathing devices with demand valves for use with a full-face mask that ensure to provide breathable air in an atmosphere that is immediately dangerous to life or health.
BS EN 14593‑1 is the first part of a multi-part series that specifies minimum requirements for compressed airline breathing devices with a demand valve for use with a full-face mask as a respiratory protective device (RPD).
Under BS EN 14593‑1 laboratory and practical performance tests are included for the assessment of conformance to the requirements.
Note1: RPD used in abrasive blasting operations without additional protective features are not covered under BS EN 14593‑1.
Note2: Escape RPD, although certain requirements addressing the use in conjunction with escape RPD and escape conditions are given, are not covered under BS EN 14593‑1.
Note3: Diving RPD is not covered under BS EN 14593‑1.
Who is BS EN 14593‑1-Requirements, testing, and marking for compressed airline breathing devices with demand valves for?
BS EN 14593‑1 on requirements, testing, and marking for compressed airline breathing devices with demand valves is useful for:
- Compressed airline breathing device manufacturers
- Compressed airline breathing device testing laboratories/test personnel
- Occupational health and safety departments
- Quality assurance authorities
Why should you use BS EN 14593‑1-Requirements, testing, and marking for compressed airline breathing devices with demand valves?
A compressed air breathing device is a type of respiratory protection equipment that provides breathable air from cylinders containing compressed air.
BS EN 14593‑1 provides you with requirements, test methods, practical performance, test procedures, marking, and much more.
The requirements and test methods provided by BS EN 14593‑1 assist in improving the performance of the compressed air breathing devices to provide maximum respiratory protection.
By adopting BS EN 14593‑1 the user can improve the efficacy of the compressed air breathing devices and help enhance the product’s standard and quality.
What is changed since the last update?
BS EN 14593‑1:2018 supersedes EN 14593‑1:2005, which is withdrawn. BS EN 14593‑1:2018 has made some technical changes compared to the previous edition EN 14593‑1:2005. These include:
- Visual inspection changed to inspection and a detailed list was inserted.
- A test for leak tightness is added
- Test for noise level adapted to the test procedure is specified in ISO 16900‑14.
- Figures adapted to the changes made in the test procedures, where appropriate
