Foreword
This document (prEN 374-1:2009) has been prepared by Technical Committee CEN/TC 162 “Protective
clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 374-1:2003.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EC Directive 89/686/EEC.
For relationship with EC Directive, see informative Annex ZA, which is an integral part of this document.
1 Scope
This standard specifies the requirements for gloves to protect the user against chemicals and/or micro-
organisms and defines terms to be used.
This standard shall be used in conjunction with EN 420.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
protective glove material
any material or combination of materials used in a glove for the purpose of isolating the hands or hands and
arms from direct contact with a chemical and/or micro-organism
3.2
protective gloves against chemicals
gloves fulfilling the requirements of clause 5.1
3.3
protective gloves against chemical of interest
gloves fulfilling the requirements of clause 5.2

1) under development
3.4
protective gloves against micro-organisms
at this time it is believed that gloves which resist penetration, when tested according to clause 5.3, form an
effective barrier to bacteria, virus and fungi
3.5
degradation
deleterious change in one or more properties of a protective glove material due to contact with a chemical.
These changes include flaking, swelling, disintegration, embitterment, discolouration, dimensions,
appearance, hardening, softening, etc
3.6
Penetration
movement of a chemical and/or micro-organism through porous materials, seams, pinholes, or other
imperfections in a protective glove material on a non-molecular level
3.7
permeation
process by which a chemical moves through a protective glove material on a molecular level. 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.
3.8
test chemical
chemical or mixture of chemicals that is used to determine the breakthrough time in the laboratory test
conditions. The chemical will be one which causes adverse effects on the skin or to the human body by
contact with the skin
3.9
breakthrough time
elapsed time between the initial application of a test chemical to the outside surface of a protective glove
material and its subsequent presence on the other side of the material, measured as described in EN 374-3
4 Methods of testing
Detailed test methods will be found in the following parts of this standard:
 Penetration: EN 374-2
 Permeation: EN 374-3
 Degradation : prEN 374-4 (under development)
5 Performance requirement
5.1 Gloves against chemicals
5.1.1 Penetration
Gloves shall not leak when tested according to the test methods in the corresponding clauses of EN 374-2
and both tests shall be passed according to the criteria in the relevant clauses of EN 374-2. If one test proves
unsuitable, the reasons shall be reported.
5.1.2 Permeation
Each combination protective glove/test chemical is classified, in terms of breakthrough time, according to each
individual chemical for which the glove resists permeation. The chemicals are tested in accordance with
EN 374-3.
NOTE 1: The performance levels given below are based on breakthrough times determined during constant contact
with the test chemical under standard laboratory conditions as described in EN 374-3. The actual duration of protection
provided in the workplace may vary considerably from these performance levels.
NOTE 2: Results from the permeation test may indicate a relative long breakthrough time while results from degradation
tests may indicate severe physical changes early and vice versa permeations test may indicate short breakthrough time
without any visible changes.
Table 1 — Permeation performance levels
Measured breakthrough time Permeation performance
(min) level
> 10 1
> 30 2
> 60 3
> 120 4
> 240 5
> 480 6
A glove shall have at least a permeation performance level 2 when tested against three chemicals taken from
the list of test chemicals in Annex A.
5.1.3 Mechanical characteristics
For each glove style recommended for use against chemicals and/or micro-organisms the obtained
performance level shall be reported in the instructions supplied by the manufacturer for the following
mechanical tests:
 Abrasion resistance,
 Blade cut resistance,
 Tearing resistance,
 Puncture resistance,
according to the test methods described in EN 388.
5.2 Protective glove against chemical of interest
5.2.1 Penetration
Gloves shall not leak when tested according to the test methods in the corresponding clauses of EN 374-2
and both tests shall be passed according to the criteria in the relevant clauses of EN 374-2. If one test proves
unsuitable, the reasons shall be reported.
5.2.2 Permeation
At least one chemical of interest as defined by clause 3.8. shall be tested according to EN 374-3 with a
minimum performance level 2 (see table 1)
Each combination protective glove/test chemical is classified, in terms of breakthrough time, according to each
individual chemical for which the glove resists permeation.
NOTE 1: The performance levels given below are based on breakthrough times determined during constant contact
with the test chemical under standard laboratory conditions as described in EN 374-3. The actual duration of protection
provided in the workplace may vary considerably from these performance levels.
NOTE 2: Results from the permeation test may indicate a relative long breakthrough time while results from degradation
tests may indicate severe physical changes early and vice versa permeations test may indicate short breakthrough time
without any visible changes
