Development of a field method for evaluating the service life of organic vapor cartridges : results of laboratory testing using carbon tetrachloride. Part II : humidity effects / Howard J. Cohen, Edward T. Zellers and Richard P. Garrison

Sumario: Results of further studies on the use of small carbon-filled glass tubes, referred to as respirator carbon tubes (RCTs), for predicting the service lives of organic-vapor respirators cartridges, are presented. Organic vapors are drawn through the RCT using a personal sampling pump until breakthrough is detected. This report examines the effects of relative humidity (HR) and prehumidification of the RCT and cartridge carbon beds on the predictive accuracy of the method
