1   Scope

This part of ISO 16900 specifies the test method for determining the gas capacity of separate or integral gas filters and combined filters for respiratory protective devices. It includes the validation test at specified flow rates, a desorption test to access the ability of the filter to retain the adsorbed or absorbed gas, and carbon monoxide dynamic testing.

NOTE These tests are conducted in laboratories using specified test agents under specified conditions and therefore do not indicate the performance of the device in actual use.
