OUTER SHELL CRITERIA

The outer shell probably has the most demanding role in the total configuration of a turnout. It has two critical functions: to resist ignition from direct flame impingement and to protect the internal layers from rips, tears, slashes, abrasion, etc. Some outer shell materials can have modest impact on TPP tests or can resist water absorption better than others. The real test of an outer shell material is its ability to maintain its protective qualities under high thermal loads and to stand up on the fireground.
