EN ISO 374-1: 2016

Chemical protective gloves

Three test methods:
- Penetration test according to EN 374-2: 2014
- Permeation test according to the standard EN 16523-1: 2015 which it replaces

the standard EN 374-3
- Degradation test according to EN 374-4: 2013 standard

Type of glove	Requirement
Type A	Waterproofing ( EN 374-2) Breakthrough time ≥ 30 min for at least 6 chemicals from the new list ( EN 16523-1)
Type B	Waterproofing ( EN 374-2) Breakthrough time ≥ 30 min for at least 3 chemicals from the new list ( EN 16523-1)
Type C	Waterproofing ( EN 374-2) Breakthrough time ≥ 10 min for at least 1 chemicals from the new list ( EN 16523-1)

Degradation test

(Alteration of the physical properties of the glove in contact with a chemical product) according to the standard EN 374-4: 2013
In order for a glove to be declared suitable for protection against a chemical on the list, permeation and degradation tests must be performed.
The results of the degradation test must be declared in the information note.
Six new chemical elements have been added to the list:

Code letter	Chemical Agent	Class
A	Methanol	Primary alcohol
B	Acetone	Ketone
C	Acetonitrile	Nitrile
D	Dichloromethane	Chlorate hydrocarbon
E	Carbon disulfide	Compound of sulfur
F	Toluene	Aromatic hydrocarbon
G	Diethylamine	Amines
H	Tetrahydrofuran	Ethers
I	Ethyl acetate	Ethers
J	N-Heptane	Saturated hydrocarbon
K	Sodium hydroxide 40%	Inorganic base
L	Sulfuric acid 96%	Inorganic mineral acid, oxidant
M	Nitric acid 65%	Mineral acid
N	Acetic acid 99%	Organic acid
O	Ammonia 25%	Organic base
P	Hydrogen peroxide 30%	Peroxide
S	Acido fluoridrico 40%	Inorganic mineral acid
T	Formaldeide 37%	Aldehyde
