The chemical permeation performance rating of a glove measures the rate at which chemicals pass through the material on a molecular level. When a glove is tested in accordance with ASTM F739-12, the chemical permeation performance is classified as shown below:
|Niveau||Variation de %|
Longer times indicate better chemical permeation resistance.
It is based on three test methods:
To be able to claim protection against a chemical of the list, permeation and from now degradation tests must be carried out. The results of the degradation test must appear in the information leaflet.
|Level||Breakthrough Time (minutes)|
The permeation performance index expresses the passage time of the product through the sample.
|K||Sodium Hydroxide 40%|
|L||Sulfuric Acid 96%|
The American National Standards Institute / International Safety Equipment Association (ANSI/ISEA) 105-2016 American National Standard for Hand Protection Classification is the latest revision of a voluntary consensus standard first published in 1999, and revised in 2005, 2011 and 2016.
This standard addresses the classification and testing of hand protection for specific performance properties related to chemical and industrial applications. It provides, or refers to, appropriate test methods and provides pass/fail criteria used by manufacturers to classify their products. End users can use this information to review the documentation received from their supplier to help verify the gloves they are considering meet their needs.
