Description:
The objective of the study was to evaluate several low-temperature characteristics of Challenge 5100, a new protective clothing material developed by Chemical Fabrics Corporation. The low temperature characteristics of three other protective clothing materials were also evaluated and used as a basis for comparison and interpretation of the Challenge results. The other clothing materials were chlorinated polyethylene, polyvinyl chloride/nylon, and butyl/nylon/butyl. The results of two stiffness tests indicated that the stiffening characteristics of the Challenge 5100 material as a function of temperature are comparable to those of polyvinyl chloride/nylon. Chlorinated polyethylene exhibited the most stiffening as the temperature was lowered, and butyl/nylon/butyl exhibited the least stiffening. The results of the hardness measurements indicate similar material performance. Since the results of both stiffness tests are in agreement with the known field performances of the materials, either test method can be used to evaluate clothing materials.
