Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
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 ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 94, Personal safety — Protective clothing and
equipment, Subcommittee SC 13, Protective clothing, and by Technical Committee CEN/TC 162, Protective
clothing including hand and arm protection and lifejackets in collaboration.

— include a definition for hole;
— modify the clause in design requirements regarding garment overlaps;
— modify the clause in design requirements regarding garment sizes;
— modify the clause on sampling requirements;
— modify clause for ageing due to washing (maximum number of cleaning procedures as indicated by
the manufacturer);

Introduction
The purpose of this International Standard is to provide minimum performance requirements for
clothing for use in welding and allied processes.
For complete protection against exposure to heat and flame, it will be necessary to protect the head, face,
hands, and/or feet with suitable personal protective equipment (PPE) and in some cases, appropriate
respiratory protection might also be considered necessary.
[2]
Attention is drawn to ISO/TR 2801:2007, which sets out guidelines for selection, use, care, and
maintenance of protective clothing against heat and flame.
Nothing in this International Standard is intended to restrict any jurisdiction, purchaser, or manufacturer
from exceeding these minimum requirements.

SIST EN ISO 11611:2015
INTERNATIONAL STANDARD ISO 11611:2015(E)
Protective clothing for use in welding and allied processes
1 Scope
This International Standard specifies minimum basic safety requirements and test methods for protective
clothing including hoods, aprons, sleeves, and gaiters that are designed to protect the wearer’s body
including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes
with comparable risks. For the protection of the wearer’s head and feet, this International Standard is
only applicable to hoods and gaiters. This International Standard does not cover requirements for feet,
hand, face, and/or eye protectors.
This type of protective clothing is intended to protect the wearer against spatter (small splashes of
molten metal), short contact time with flame, radiant heat from an electric arc used for welding and
allied processes, and minimizes the possibility of electrical shock by short-term, accidental contact with
live electrical conductors at voltages up to approximately 100 V d. c. in normal conditions of welding.
Sweat, soiling, or other contaminants can affect the level of protection provided against short-term
accidental contact with live electric conductors at these voltages.
For adequate overall protection against the risks to which welders are likely to be exposed, personal
protective equipment (PPE) covered by other International Standards should additionally be worn to
protect the head, face, hands, and feet.
Guidance for the selection of the type of welders clothing for different welding activities is detailed in
Annex A.
