1. Scope
1. Scope 1.1 This standard specification covers the retained sewn seam strength of flame resistant fabric subassemblies after repeated short duration exposures to hot air and a subsequent exposure to an open flame impingement. 1.1.1 The objective of this specification is to determine minimum retained sewn seam strength after these exposures.
Sewn seam strength of flame resistant textile products is a critical measurement of structural integrity. This is particularly important for (FR) protective clothing, which is designed to provide safety to any worker who may, during the service life of the PPE, experience multiple short term exposures to high heat. While new FR protective clothing items can provide the wearer with protection that meets a specific performance requirement, it is useful to know what the cumulative effects of repeated exposures to high heat can do to the integrity of the sewn seams used to construct protective clothing items. In addition, it is useful to know how the cumulative exposures can affect the sewn seam strength performance of the PPE when exposed to an open flame for a short period of time.
