What is BS EN 148-1- Standard thread connection for facepieces in respiratory protective devices about?
BS EN 148 discusses respiratory protective devices. BS EN 148-1 is an international standard on standard thread connection for facepieces in respiratory protective devices to ensure protection against hazardous air in the workplace.
BS EN 148-1 is the first part of a multi-part series that specifies standard threads for respiratory protective devices and the description of test devices necessary for the assessment of some of the requirements.
BS EN 148-1 does not apply to diving equipment and positive pressure-demand breathing apparatus.
Who is BS EN 148-1- Standard thread connection for facepieces in respiratory protective devices for?
BS EN 148-1 on standard thread connection for facepieces in respiratory protective devices is useful for:
- Facepiece manufacturers
- Facepiece designers
- Safety and health departments
- Any entity related to the production of respiratory protective devices
Why should you use BS EN 148-1- Standard thread connection for facepieces in respiratory protective devices?
Respirators protect workers against insufficient oxygen environments, harmful dust, fogs, smoke, mists, gases, vapors, and sprays. These hazards may cause cancer, lung impairment, diseases, or death.
BS EN 148-1 assist you by specifying the requirements for elements of thread connection, the geometry of thread profile, for making measurements on the connection, and ensuring the facepieces provide protection again hazardous air at the workplace.
By using the physical and mechanical requirements of the thread connection sealing element specified by BS EN 148-1 the user can ensure the resistance of the connectors to pull forces and enhance the performance of facepieces.
