CHEMICAL GLOVE RESISTANCE CHART

ASTM Breakthrough Time and CPC Rating
ASTM F739-91 Normalized Breakthrough in Minutes and CPC Rating for Gloves

Explanation of Ratings
Breakthrough detection times (BDT) are given in minutes. CPC index rating are based on the system of Forsberg which relies on both breakthrough times and permeation rates to establish a rating system for chemical protective clothing. The ratings range from 0 to 5 with 0 being the best and 5 the worst.

Chemical Protective Clothing Performance
Index Rating Summary (CPC)
0  Safest Selection for Unlimited Exposure. No Breakthrough.
1  Next Best Selection for Unlimited Exposure.
2  Sometimes Satisfactory. Good for Limited Exposure.
3  Poor Choice. Not for Heavy Exposure.
4  Very Poor. For Splashes Only.
5  Not Recommended
