Field of application is the research of personal protective equipment (PPE)
- The transport of a substance through personal protective equipment (PPE) to human skin (permeation) should be prevented by wearing PPE.
- A maximum wearing time depends to a significant extent on the resistance of the personal protective equipment (PPE) to the respective hazardous substance and the type of activity performed.
- Chemical protective gloves and clothing must therefore have a minimum temporal resistance to the invisible penetration (permeation) of chemicals in accordance with their practical use.
- This resistance is simulated according to the test method of the standards EN 16523-1:2015-04 and EN 16523-1:2015-04 (formerly DIN EN 374-3) by determining the breakthrough time experimental.
- The large number of chemical substances, the mandatory recommendation of a suitable PPE material in a chemical safety data sheet, and even the smallest changes in the PPE material composition during manufacture require a large number of permeation tests.
LABC-Labortechnik develops permeation workstations for the standardized performance of meaningful measurements. The standards EN 16523, EN 374, EN 6529 and F-739.
The standards specify lists of test chemicals, known as permeation chemicals. In addition, the appropriate measurement method is given for each permeation chemical. As a rule, the lists are included in the informative annex.
The three different analytical instruments of LABC-Labortechnik cover all permeation chemicals.
