1.1 ,This guide describes options for conformity assessment (CA) requirements relating to personal protective clothing and equipment (hereafter referred to as “,PPE”,). This guidance can optionally be used to define conformity assessment requirements in a PPE specification standard or in a companion ASTM conformity assessment Standard Practice document2 associated with the PPE specification standard. It is understood that the former approach is not consistent with ISO Directive, Part 2, Section 6.7.
