Protective gloves - General requirements and test methods (ISO 21420:2020)

This standard defines the general requirements and relevant test procedures for glove design and construction, resistance of glove materials to water penetration, innocuousness, comfort and efficiency, marking and information supplied by the manufacturer applicable to all protective gloves.
NOTE   It can also be applicable to arm protectors and gloves permanently incorporated in containment enclosures.
This European Standard does not address the protective properties of gloves and therefore should not be used alone but only in combination with the appropriate specific European Standard(s).
A non exhaustive list of these standards is given in the Bibliography.

Schutzhandschuhe - Allgemeine Anforderungen und Prüfverfahren (ISO 21420:2020)

Dieses Dokument legt die für alle Schutzhandschuhe anwendbaren allgemeinen Anforderungen und die relevanten Prüfverfahren zu Gestaltungsgrundsätzen, Handschuhkonfektionierung, Unschädlichkeit, Komfort und Leistungsvermögen sowie für die vom Hersteller vorgenommene Kennzeichnung und mitgelieferte Informationen fest.
Es kann auch für Armschutz und Handschuhe gelten, die dauerhaft in geschlossenen Behältnissen integriert sind.
Von diesem Dokument werden z. B. Handschuhe und Handschützer wie Fäustlinge, Topflappen und Armschützer erfasst.
Dieses Dokument befasst sich nicht mit den schützenden Eigenschaften von Handschuhen und wird daher nie alleine, sondern nur in Kombination mit den zutreffenden spezifischen Normen angewendet. Eine nicht abschließende Liste dieser Normen enthalten die Literaturhinweise.

Gants de protection - Exigences générales et méthodes d’essai (ISO 21420:2020)

Le présent document définit les exigences générales et les méthodes d'essai concernant la conception et la construction du gant, l'innocuité, le confort et l'efficacité, ainsi que le marquage et les informations fournies par le fabricant applicables à tous les gants de protection.
Le présent document peut aussi s'appliquer aux protecteurs du bras et aux gants incorporés de manière permanente à des enceintes fermées.
Le présent document couvre les gants et protecteurs de la main tels que les mitaines, maniques et protections du bras.
Le présent document ne concerne pas les propriétés de protection des gants et n'est donc pas utilisé seul mais seulement en association avec la ou les normes spécifiques appropriées. Une liste non exhaustive de ces normes est donnée dans la Bibliographie.

Protective gloves — General requirements and test methods
1 Scope
This document specifies the general requirements and relevant test procedures for glove design and
construction, innocuousness, comfort and efficiency, as well as the marking and information supplied
by the manufacturer applicable to all protective gloves.
It can also apply to arm protectors and gloves permanently incorporated in containment enclosures.
Gloves and hand protectors such as mittens, pot holders and arm protection are covered by this
document.
This document does not address the protective properties of gloves and therefore is not used alone but
only in combination with the appropriate specific standard(s). A non-exhaustive list of these standards
is given in the Bibliography.

3.7
level of performance

testing can be graded
Note 1 to entry: The level of performance is determined by the result of the corresponding test as described in
the specific standards referred to in the Bibliography.
Note 2 to entry: A high level number or letter corresponds to a high level of performance.
Note 3 to entry: Levels of performance are based upon the results of laboratory tests, which do not necessarily
reflect actual conditions in the workplace.
3.8
multilayer gloves
gloves containing more than one layer with some level of permanent connection between the layers.
4 General requirements
4.1 Glove design and construction — General
The protective glove shall be designed and manufactured so that in the foreseeable conditions of use,
the wearer can perform the activity as normally as possible with an appropriate protection. This
document along with the appropriate specific standards shall be used to verify this adequation.
If required in the relevant specific standard (for example ISO 16073:2011, 5.7.3), the glove shall be
designed to minimize the donning and doffing time.
For reusable multilayer gloves, the gloves shall be able to be doffed without separation of the layers
of the fingers. When the glove construction includes seams, the material and strength of the seams
shall be such that the overall performance of the glove is not significantly decreased as required in the
relevant specific standards.
Test methods and requirements are stated in the specific standards listed in the Bibliography. The
number of samples shall be as stated in the specific standard. If the standard requests at least x samples
then x samples shall be tested. For uncertainties of measurement, see Annex D.
4.2 Innocuousness of protective gloves
Protective gloves shall not adversely affect the health or hygiene of the user. The materials should not, in
the foreseeable conditions of normal use, release substances generally known to be toxic, carcinogenic,
mutagenic, allergenic, toxic to reproduction, corrosive, sensitizing or irritating.
NOTE 1 Information on the classification and identification of hazardous substances can be found, e.g. in
References [22] and [27].
NOTE 2 Guidance on how to consider acceptability of materials in protective gloves is given in the flow chart
in Annex E.
Materials should be selected to minimize the environmental impact of the production and disposal of
protective gloves (see also Annex F).
The examination shall determine whether the claim that the materials are suitable for use in the
protective gloves is justified. Particular attention shall be paid to the presence of plasticisers, unreacted
components, heavy metals, impurities and the chemical identity of pigments and dyes.
a) Chromium VI content in gloves containing leather shall be tested according to ISO 17075-1 or
ISO 17075-2 and shall be less than 3,0 mg/kg of leather.
Depending on the measured Chromium VI content, the test report shall indicate:
© ISO 2020 – All rights reserved 3

---------------------- Page: 15 ----------------------
SIST EN ISO 21420:2020
ISO 21420:2020(E)

— that the Chromium VI content is less than 3,0 mg/kg, or
— that Chromium VI content is equal to or above 3,0 mg/kg and the value that has been determined
in mg/kg.
If the glove includes different types of leather, whether in contact with the skin or not, each leather
type shall be tested separately and comply with the above requirement.
b) All metallic materials which could come into prolonged contact with the skin (for example studs,
2
fittings) shall have a release of nickel of less than 0,5 µg/cm per week. The method of test shall be
in accordance with EN 1811+A1: 2015.
c) All glove materials shall have a value greater than pH 3,5 and less than pH 9,5. The test method for
leather shall be in accordance with ISO 4045 and for other materials in accordance with ISO 3071.
The following additional requirements shall apply:
— the test piece shall be cut out from the palm area of the glove. If other parts of the glove are
made of different materials, then each material shall be tested separately and comply with the
above requirements;
— if gloves are made of more than one layer, all layers shall be tested separately;
— ISO 4045:2018, 8.4, does not apply.
d) Azo colorants which release carcinogenic amines listed in ISO 14362-1 for all textile materials and
ISO 17234-1 for all leathers shall not be detectable by the method in these standards.
e) Dimethylformamide (DMFa) in gloves containing PU shall not exceed 1 000 mg/kg (0,1 % weight/
weight). The test method shall be in accordance with EN 16778.
f) Polycyclic aromatic hydrocarbons (PAHs) as listed in Table 1, shall not exceed 1 mg/kg (0,000 1 %
by mass of this component), for the rubber or plastic materials intended to come in direct contact
with the skin. The test method shall be in accordance with ISO/TS 16190.
