Respiratory protective devices. Methods of test and test equipment – Determination of inward leakage
| Published By | Publication Date | Number of Pages |
| BSI | 2019 | 46 |
This document specifies the test methods for determining inward leakage of respiratory interfaces (RI) and total inward leakage of complete respiratory protective devices (RPD) using specified test agents and incorporating specified body movements, at specified metabolic work rates.
These tests are conducted in laboratories using specific test agents under specified conditions and therefore do not indicate the performance of the device in actual use.
