DIN EN 12941:2025-04

DIN EN 12941 specifies minimum requirements for powered filtering Respiratory Protective Devices (RPD) incorporating a loose fitting respiratory interface (RI). It does not apply to devices intended for use in conditions where oxygen deficiency (oxygen concentration less than 17% by volume) may occur. Escape devices (respiratory protective devices for escape purposes) are not covered by this document. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. As part of the revision, an optional mechanical vibration test has been added for devices subject to high mechanical stress. Warning devices for battery alarm, insufficient power supply, and filter saturation (insufficient volume flow) have also been added. The standard is intended for manufacturers, testing institutes, and all users of respiratory protective equipment. It deals in particular with aspects of occupational safety and (product) safety. The standard has been prepared by Technical Committee CEN/TC 79 "Respiratory protective devices". The responsible national committee is Working Committee NA 027-02-04 AA "Atemschutzgeräte" ("Occupational respiratory protective devices") at NAFuO.
