A standardization system is under development in ISO Technical Committee 94 Sub Committee 15 ISO/TC 94/SC 15 “Respiratory Protective devices” (https://www.iso.org/committee/291088/x/catalogue/). This system puts the wearer in the center and defines human factors, test methods, selection and use guidance and performance requirement standards. The selection and use standards present ISO 16975-3 “Respiratory protective devices – Selection, use and maintenance – Part 3: Fit-testing procedures”, giving information on qualitative and quantitative fit testing methods and the actual procedures.
In 2020 work started on ISO/TS 16975-4 “Respiratory protective devices — Selection, use and maintenance — Part 4: Guideline for respiratory protective devices under pandemic of infectious respiratory disease”.
