Caution: All tests for determination of breakthrough times were carried out in minutes according to the EN16523-1:2015 and EN374-3:2003 standard under laboratory conditions. The actual conditions at the working space might have an impact on the resistance to chemical permeation and can lead to varying chemical breakthrough times. All recommendations and test results are for reference purposes only and are subject to errors and revisions if updated data becomes available. The test results are no substitute for an evaluation carried out by the user.
