Standards Development
This European Standard specifies performance requirements, test methods and marking requirements for half masks (re-usable) without inhalation valves and with separable filters (designed for a maximum of single shift use) to protect against gases or gases and particles or particles only. It does not cover devices designed for use in circumstances where there is or might be an oxygen deficiency (oxygen less than 17 % by volume) or for escape purposes.
Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
Due to the new PPE Regulation and in accordance with the PPE Standardization request (not formally approved) it is necessary to revise the standards developed under the responsibility of CEN/TC 79.
In addition DECISION 12 taken by CEN/TC 79 on 2016-05-12 at the meeting in London contains the withdrawal of EN 13274-8 "Respiratory protective devices - Methods of test - Part 8: Determination of dolomite dust clogging" which was put on hold until all product standards referring to Part 8 have been revised.
