Respiratory protective devices — Selection, use and maintenance — Part 3: Fit-testing procedures

Summary

This document specifies guidance on how to conduct fit testing of tight-fitting respiratory protective
device (RPD) and on appropriate methods to be used. Fit testing is only one element of a complete RPD
programme. The intention of fit testing is to evaluate the effectiveness of the seal between the wearer’s
face and the respiratory interface (RI). A complete RPD programme is defined in ISO/TS 16975-1.
This document specifies requirements for conducting RPD fit testing and includes
— qualifications/competences of fit-test operators,
— specific fit-testing procedures,
— interpretation of fit-test results, and
— record keeping.
A fit test is not required for escape-only RPD.
