Two proposed new standards currently being developed by ASTM International Committee F23 on Protective Clothing will each contribute to the safety of protective clothing. Interested parties are invited to participate in the development of both proposed standards, which are WK14247 , Specification for Air-Fed Protective Ensembles and WK14442 , Antimicrobial Activity of Textiles Following Multiple…, WK14247, Specification for Air-Fed Protective Ensembles, Subcommittee F23.30 on Chemicals invites users and manufacturers of air-fed protective ensembles to participate in the development of a proposed new standard WK14247 . This proposed specification would establish design, performance, documentation, labeling and certification requirements for protective ensembles that rely on principal air supply to the wearer via an air line or air filtered…, WK14442, Antimicrobial Activity of Textiles Following Launderings with Bleach, Antimicrobial treatments often are applied to textiles to impart durable efficacy, reducing the survival and growth of microorganisms on the textile. A proposed new ASTM standard, WK14442 , under the jurisdiction of F23’s biological subcommittee, F23.40 , would ensure these antimicrobial agents would continue to work throughout a garment’s life span. “Over the last 10 years, the industry has…
