What is BS EN 14594-Requirements, testing, and marking for continuous flow compressed airline breathing devices about?
BS EN 14594 discusses respiratory protective devices (RPD). BS EN 14594 is a European standard on the requirements, testing, and marking for continuous flow compressed airline breathing devices that ensure to provide breathable air in an atmosphere that is immediately dangerous to life or health.
BS EN 14594 specifies minimum requirements for continuous flow compressed airline breathing devices for use with a full-face mask, half mask, hood, helmet, or suit, and devices used in abrasive blasting operations, as an RPD.
Under BS EN 14594 laboratory and practical performance tests, are included for the assessment of conformance to the requirements.
Note: Escape RPD and diving apparatus are not covered under BS EN 14594.
Who is BS EN 14594-Requirements, testing, and marking for continuous flow compressed airline breathing devices for?
BS EN 14594 on requirements, testing, and marking for continuous flow compressed airline breathing devices 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 14594-Requirements, testing, and marking for continuous flow compressed airline breathing devices?
A compressed air breathing device is a type of respiratory protection equipment that provides breathable air from cylinders containing compressed air.
BS EN 14594 provides you with requirements, test methods, practical performance, test procedures, marking and much more.
The requirements and test methods provided by BS EN 14594 assist in improving the performance of the compressed air breathing devices and ensure to provide maximum respiratory protection.
By adopting BS EN 14594 the user can improve the efficacy of the compressed air breathing devices and enhance the product’s standard and quality.
What is changed since the last update?
BS EN 14594:2018 supersedes EN 14594:2005, which is withdrawn. BS EN 14594:2018 has made some technical changes compared to the previous edition EN 14594:2005. These include:
- Visual inspection changed to inspection and a detailed list is inserted
- Test for noise level adapted to the test procedure specified in ISO 16900-14
- Requirements and test method for protective clothes specified.
- A test for leak tightness is added
- A test for leak tightness is added
- Figures adapted to the changes made in the test procedures, where appropriate
