Storage protective clothing affects longevity

A presentation on a study by the Korea Apparel Testing & Research Institute (KATRI) on the influence of the way protective clothing is stored on the life cycle was presented in the ISO working group on protective clothing against chemicals. New articles leak after 480 minutes when using methanol; for some tested articles that have been in storage for 10 years, this time has been reduced to 16 and even 3 minutes by being folded and stacked in storage. In addition to these factors, light, humidity and temperature also affect quality. The lifespan of articles made of polymers is mainly influenced by temperature. The testing and application of a temperature of 100 ° reduces the resistance to methanol from 480 minutes for a few articles to 67 minutes and even less than a minute. These findings lead to the question whether test methods for storage should be included in standards for cpc (chemical protective clothing).
