CHEMICAL PROTECTION (NO CHANGE)
Relevance to the Market:
Ansell tests to ASTM F739-12 for chemical permeation, to rate its gloves based on chemical breakthrough times, chemical permeation rates, and chemical degradation.
The 8th edition of Ansell’s Chemical Permeation Guide (available on its website) provides data for gloves tested against different chemicals. Breakthrough times are listed, and rates and degradation values categorized from Excellent to Very Good, Good, Fair
or Poor. (Some gloves are “Not rated.”) Complex measurements are color coded to simplify the selection of the best gloves Green for excellent-good, Yellow for acceptable (with caution advised),
or Red for poor-not recommended.
