The time required by the chemicals to permeate, determines the performance class in accordance with EN ISO 374-1. The actual period of protection at the workplace may vary depending on real-time process factors. Time measured to penetration Protection index > 10 min Class 1 > 30 min Class 2 > 60 min Class 3 > 120 min Class 4 > 240 min Class 5 > 480 min Class 6 EN ISO 374-1:2018 Standard for safety gloves to protect against chemical risks Chemical safety gloves must meet the requirements of European standard EN ISO 374-1. This standard has undergone fundamental changes in terms of certification. Test chemicals: From the list of 18 test chemicals, the glove material must be tested for permeation as part of the certification process using 6, 3 or 1 chemical(s), depending on the type class. DIN EN 374-5: 2016 Standard for safety gloves to protect against dangerous chemicals and micro-organisms To protect against microorganisms such as bacteria, fungi and viruses, safety gloves must undergo and pass special penetration tests in accordance with ISO 16604:2004 (method B). Only then may they be marked with the pictogram for EN ISO 374-5.
