It refers only to technical suitability and in no way absolves either the supplier or the user from statutory obligations relating to health and safety at any
11、 stage of manufacture or use. This standard specifies pentachlorophenyl laurate (PCPL) as the only approved rotproofing treatment for aerospace textiles. Alternative treatments are under development, and this standard will be updated to delete PCPL as soon as an approved alternative treatment for ae
