ABSTRACT
Four systems have been fabricated to measure the effective service life of respirator cartridges and canisters. The four systems employ carbon monoxide, sulfur dioxide/nitrogen dioxide, ammonia/methylamine, and chlorine/hydrogen chloride as contaminants. Each system produces test concentrations in the low percentage range (typically 0.05 to 3.0%) at flow rates of 32 and 64 liters/min and at relative humidities between 20 and 95%. Suitable anlyzers have been provided to measure the downstream concentration from 1 to 500 ppm as a function of time. Holders have been designed to accommodate the wide size variation of commercially available cartridges and canisters.
