Protective clothing for use in welding and allied processes (ISO 11611:2015)

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 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 of this International Standard.

Vêtements de protection utilisés pendant le soudage et les techniques connexes (ISO 11611:2015)

L'ISO 11611:2015 spécifie les exigences essentielles de sécurité minimales et les méthodes d'essai des vêtements de protection, comprenant les cagoules, les tabliers, les manches et les guêtres, destinés à protéger le corps de l'utilisateur, y compris la tête (cagoules) et les pieds (guêtres) et qui doivent être portés durant des opérations de soudage et autres techniques connexes ayant des risques comparables. Pour la protection de la tête et des pieds, l'ISO 11611:2015 s'applique seulement pour les cagoules et les guêtres. L'ISO 11611:2015 ne couvre pas les exigences pour la protection de la main, du visage et/ou des yeux.

Varovalna obleka pri varjenju in sorodnih postopkih (ISO 11611:2015)

Ta mednarodni standard določa minimalne osnovne varnostne zahteve in preskusne metode za varovalno obleko, vključno s pokrivali, predpasniki, rokavi in gamašami, ki so namenjeni za zaščito telesa uporabnika, vključno z glavo (pokrivala) in nogami (gamaše), in ki jih je treba nositi pri varjenju ter sorodnih postopkih s primerljivimi tveganji. Glede zaščite uporabnikove glave in nog se ta mednarodni standard uporablja samo za pokrivala in gamaše. Ta mednarodni standard ne zajema zahtev za zaščito nog, rok, obraza in/ali oči. Ta vrsta varovalne obleke je namenjena zaščiti uporabnika pred brizganjem (brizgom staljene kovine), kratkim stikom s plamenom, toplotnim sevanjem iz električnega obloka, ki se uporablja za varjenje in sorodne postopke. Varovalna obleka tudi zmanjšuje možnost električnega udara, ki lahko nastane zaradi kratkega, nenamernega stika z živimi električnimi vodniki pri enosmerni napetosti do približno 100 V v normalnih pogojih varjenja. Znoj, umazanija ali druga nesnaga lahko vplivajo na raven zaščite pred kratkotrajnim stikom z živimi električnimi vodniki pri tej napetosti. Za ustrezno splošno zaščito pred tveganji, ki so jim izpostavljeni varilci, je treba dodatno nositi osebno varovalno opremo (PPE) za glavo, obraz, roke in noge, ki je opisana v drugih standardih. Smernice za izbor vrste oblačil za varilce, ki opravljajo različne dejavnosti varjenja, so podrobno opisane v Dodatku A tega mednarodnega standarda.

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.

This second edition cancels and replaces the first edition (ISO 11611:2007) which has been technically

revised with the following changes:
— include an introduction;
— 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

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.

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.
