The impact of health care related infections is a global concern, and hands are a leading means of direct or indirect transport of infectious microorganisms. A task group within Subcommittee D11.40 on Consumer Rubber Products has begun to develop standards focused on preventing that transfer through the use of antimicrobial agents on gloves. D11.40 is part of ASTM International Committee D11 on…

Residual accelerator chemicals in medical gloves appear to be a leading cause of allergic contact dermatitis in health care workers. A new ASTM International standard allows rubber glove manufacturers to monitor the level of residual chemicals in their end products and to potentially make manufacturing changes to reduce allergen levels. The new standard, D7558 , Test Method for Colorimetric/…
