This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 162.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

European foreword
This document (prEN 12477:2021) 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 12477:2001 and EN 12477:2001/A1:2005.
In comparison with the previous edition, the following technical modifications have been made:
— reference to new standard EN 388, EN 407, EN ISO 21420, etc.;
— new TDM test coming from EN 388;
— new gloves length, Table 1;
— new pictogram.
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 EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.

Introduction
There are various manual welding processes, which are defined in ISO/TR 25901-3:2016, “Welding and
allied processes — Vocabulary — Part 3: Welding processes”.
The nature and the severity of the risks for welders' hands vary according to the various welding
processes. The performance (protection and dexterity) required for protective gloves can therefore
differ depending on their intended use.

1 Scope
This document specifies requirements and test methods for protective gloves for use in manual metal
welding, cutting and allied processes.
Protective gloves for welders protect the hands and the wrists during the process of welding and
related tasks.
Protective gloves for welders protect against small splashes of molten metal, short contact exposure to
limited flame, convective heat and contact heat and U.V. radiation from the arc. The glove’s material
provides minimum electrical resistance up to 100 V (DC) for arc welding. Besides, they protect against
mechanical aggressions.
WARNING — It is not meant to bring any protection in case of defective or wrong use of the welding
equipment. It does not qualify the glove for protection against electrical shock where protective gloves
designed according to EN 60903 shall be used.
According to their performance, protective gloves for welders are classified into two types:
— Type A: lower dexterity (with higher other performance);
— Type B: higher dexterity (with lower other performance).
Protective gloves for special welding processes are outside the scope of this document.
