| Abstract |
Part I (Experimental design) describes the apparatus and test materials developed and used for determining the service life of respirator cartridges in atmospheres containing organic vapours. The cartridges are placed in a holder, and breakthrough times are determined by measuring the upstream and downstream concentrations. Breakthrough characteristics can be ascertained by using either a steady-state flow or a cycling flow produced by a breath simulator. Part II (Preparation of test atmospheres) describes the design and operation of the apparatus used to produce test atmospheres of known composition. Concentrations from 1 to more than 1000ppm can be generated at variable airflows, and humidity can be adjusted from 1 to 95%. |
