SAFETY – PPE TECHNICAL TIP HAND PROTECTION EN ISO 374 – Chemical protection and/or protection against micro-organisms This standard specifies the capability of gloves to protect the user against chemicals and/or micro-organisms. Micro-organisms EN 374:2003 Performance levels EN level ＿ >2 Old: AQL (Acceptable Quality Level) for liquid penetration. A high index number is poor and a low index number is good. Gloves need to pass water and air leak test, and this test method remains unchanged as per the new EN ISO 374 standard. EN ISO 374-5:2006 New: In addition to testing for protection from bacteria and fungi, each glove can be tested for its protection against viruses with a new viral penetration test. 1 2 3 4.0 1.5 0.65 VIRUS Chemical protection EN 374:2003 XYZ EN ISO 374-1:2016 Type C EN ISO 374-1:2016 Type B Old: breakthrough time > 30 minutes for at least three chemicals from this list (XYZ represent the code letters for three of these chemicals for which the glove obtained > 30 minutes breakthrough time) New: Type C At least Level 1 performance (more than 10 minutes) against at least one chemical on the list – cuffs are also tested.* Type B At least Level 2 performance (more than 30 minutes) against at least three chemicals on the list – cuffs are also tested.* A.
