GUIDE TO HAND PROTECTION STANDARDS
EN 374-4:2013 Degradation is the deleterious change in one or more properties of a protective glove material
Resistance to chemical degradation due to contact with a chemical. Indications of degradation can be delaminating, discoloration,
hardening, softening, dimensional change, loss of tensile strength, etc. It is determined
by measuring the percentage change in puncture resistance of the glove material after a
continuous contact for 1 hour of the external surface with the challenge test chemical. The
results of the degradation test must appear in the information leaflet for all three glove types.
EN ISO 374-5:2016 Micro-organisms are defined by the standard as bacteria, fungi or viruses. To claim resistance
Protection against micro-organisms to bacteria and fungi the glove must pass the penetration resistance test according to standard
EN 374-2: 2014. If the glove passes ISO 16604: 2004 (method B) test it can claim resistance to
EN ISO 374-5 EN ISO 374-5 viruses as well, and the term “VIRUS” will be added below the biohazard pictogram.
VIRUS
EN ISO 374-1:2016 The standard defines requirement the capability of gloves to protect the user against
penetration, permeation and degradation by chemicals and microorganisms. It classifies three
types of gloves by level of protection (A, B, and C) using test method EN16523-1:2015.
EN374-2:2014 The gloves must pass the air leak and/or water leak test, and meet the defined AQL inspection
Penetration resistance level. In an air leak test the interior of glove is pressurized with air and the surface is checked
for holes. In a water leak test the glove is filled with water, and checked for the appearance of
water droplets on the outside surface after a defined time period.
AQL (accepted quality level) is a measure of quality assurance based on random sampling
procedure according to ISO 2859-1 used by manufacturers for measuring the likelihood of
pinhole defects in a batch of gloves. An AQL of 1,5 accepts the statistical probability that there
are less than 1,5% of the gloves with defects in the batch.
Performance level Acceptable quality level unit Inspection levels
Level 3 < 0,65 G1
Level 2 < 1,5 G1
Level 1 < 4,0 S4
