Respiratory protective devices. Methods of test - Determination of inward leakage and total inward leakage Ingestion-build-44616 What is ISO/IEC TS 17021-81 Scope This European Standard specifies the general procedure for determining: a) the inward leakage of facepieces; or b) inward leakage of respiratory protective devices (RPD), which is the total inward leakage excluding any filter penetration; or c) total inward leakage of respiratory protective devices. Device preparation, selection of test subjects, test procedure and the method of calculation of leakage are included. Two methods are described,
