For the purposes of this document, the terms and definitions in EN 16523-1:2015+Amd 1:2018 and the
following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
dangerous chemicals
chemical substance potentially hazardous for the health (carcinogenic, mutagenic, reprotoxic, toxic, harmful,
corrosive, irritant, sensitizing), as defined in any national regulation
3.2
degradation
deleterious change in one or more properties of a protective glove material (3.6) due to contact with a
chemical
Note 1 to entry: Indications of degradation may include flaking, swelling, disintegration, embrittlement, colour change,
dimensional change, appearance, hardening, softening, etc.
3.3
penetration
movement of a chemical through materials, seams, pinholes, or other imperfections in a protective glove
material (3.6) on a non-molecular level
3.4
permeation
process by which a chemical moves through a protective glove material (3.6) on a molecular level
Note 1 to entry: Permeation involves the following:
— absorption of molecules of the chemical into the contacted (outside) surface of a material;
— diffusion of the absorbed molecules in the material;
— desorption of the molecules from the opposite (inside) surface of the material.
3.5
protective gloves against dangerous chemical
protective gloves which form a protective barrier to dangerous chemicals (3.1)
3.6
protective glove material
any material or combination of materials used in a protective glove for the purpose of isolating the hands or
hands and arms from direct contact with a dangerous chemical
3.7
test chemical
chemical substance, or mixture of chemical substances, potentially hazardous to the health that is used
under laboratory test conditions to determine the breakthrough time
4 Sampling
4.1 Sampling for permeation
Each protective glove material specimen to be tested shall conform to the requirement in EN 16523-
1:2015+Amd 1:2018, Clause 7, so that the protective glove material can be sealed inside the test cell.
Three test specimens shall be taken from the palm area. If the glove is longer than or equal to 400 mm and
if the cuff is claimed to protect against chemical risks, three additional test specimens shall be taken where
the centre is approximately at 80 mm from the end of the cuff (see Figure 1).
Other parts of the glove can be tested on request. In the case of seams in the hand area, this area shall be
tested. For multilayer protective gloves against chemicals, in the case of layers not bonded to the protective
layer against chemical, the layers not claiming any effect on the chemical protection can be removed, i.e.
thermal insulation layer.

4.3 Sampling for degradation testing
The sampling for degradation shall be done according to 4.1 and ISO 374-4:2019, 5.1.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.

3 Terms and definitions
For the purposes of this document, the terms and definitions in EN 16523-1:2015+Amd 1:2018 and the
following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
dangerous chemicals
chemical substance potentially hazardous for the health (carcinogenic, mutagenic, reprotoxic, toxic, harmful,
corrosive, irritant, sensitizing), as defined in any national regulation
ISO/FDIS 374-1:2024(en)
3.2
degradation
deleterious change in one or more properties of a protective glove material (3.6) due to contact with a
chemical
Note 1 to entry: Indications of degradation may include flaking, swelling, disintegration, embrittlement, colour change,
dimensional change, appearance, hardening, softening, etc.
3.3
penetration
movement of a chemical through materials, seams, pinholes, or other imperfections in a protective glove
material (3.6) on a non-molecular level
3.4
permeation
process by which a chemical moves through a protective glove material (3.6) on a molecular level
Note 1 to entry: Permeation involves the following:
— absorption of molecules of the chemical into the contacted (outside) surface of a material;
— diffusion of the absorbed molecules in the material;
— desorption of the molecules from the opposite (inside) surface of the material.
3.5
protective gloves against dangerous chemical
protective gloves which form a protective barrier to dangerous chemicals (3.1)
3.6
protective glove material
any material or combination of materials used in a protective glove for the purpose of isolating the hands or
hands and arms from direct contact with a dangerous chemical
3.7
test chemical
chemical substance, or mixture of chemical substances, potentially hazardous to the health that is used
under laboratory test

bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of
ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
