• Description:
  A comparative study of different test systems for evaluating chemical protective clothing breakthrough time was conducted. The permeation of acetone (67641) through samples of neoprene was measured in test systems using a photoionization detector in open and closed loop configurations and a closed loop infrared system operated at circulation flow rates of 0.5 and 8.0 liters per minute (lpm). The American Society for Testing and Materials (ASTM) F739- 85 standard test method was used for comparison purposes. The mean breakthrough time obtained in the infrared detection system at a flowrate of 8.0lpm was 9.0 minutes (min) and was 17.5min at a flowrate of 0.5lpm. Mean breakthrough times measured by the photoionization detector in the open and closed loop systems were 18.5 and 16.2min, respectively. The mean breakthrough time obtained by the ASTM method was 17.8min. The limit of detection for the infrared system was 0.29 part per million (ppm) while limits for the open and closed loop photoionization detector systems were 1.20 and chemical permeation data is complicated by factors related to the test system such as sensitivity, fluctuations in flowrate, and whether an open or closed loop sampling system is used.
