This part of ISO 16900 specifes the test method for determining the gas capacity of separate or integral gas flters and combined flters for respiratory protective devices. It includes the validation test at specifed fow rates, a desorption test to access the ability of the flter to retain the adsorbed or absorbed gas, and carbon monoxide dynamic testing.
NOTE These tests are conducted in laboratories using specifed test agents under specifed conditions and therefore do not indicate the performance of the device in actual use.
