Protective clothing - Clothing to protect against heat and flame - Minimum performance requirements (ISO 11612:2015)

This International Standard specifies performance requirements for protective clothing made from flexible
materials, which are designed to protect the wearer’s body, except the hands, from heat and/or flame. For
protection of the wearer’s head and feet, the only items of protective clothing falling within the scope of this
International Standard are gaiters, hoods and overboots. However, concerning hoods, requirements for visors
and respiratory equipment are not given.
The performance requirements set out in this International Standard are applicable to protective clothing which
could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread
properties and where the user can be exposed to radiant or convective or contact heat or to molten metal
splashes
This International Standard is not applicable to protective clothing that is specified by other International
Standards (see introduction).

Schutzkleidung - Kleidung zum Schutz gegen Hitze und Flammen (ISO 11612:2015)

Diese Internationale Norm legt die Leistungsanforderungen an Schutzkleidung fest, die aus flexiblen Materialien besteht und zum Schutz des Körpers, mit Ausnahme der Hände, des Trägers gegen Hitze und/oder Flammen vorgesehen ist. Zum Schutz von Kopf und Füßen des Trägers sind als Schutzkleidung nur Gamaschen, Hauben und Überschuhe im Anwendungsbereich dieser Internationalen Norm enthalten. In Bezug auf Hauben werden jedoch keine Anforderungen an Sichtscheiben und Atemgeräte gegeben.
Die Leistungsanforderungen nach dieser Internationalen Norm gelten für Schutzkleidung, die für einen weiten Bereich von Endanwendungen vorgesehen sind, bei denen Kleidung mit begrenzter Flammenausbreitung erforderlich ist und bei denen der Träger Strahlungswärme, konvektiver oder Kontaktwärme oder Spritzern geschmolzenen Metalls ausgesetzt ist.
Diese Internationale Norm gilt nicht für Schutzkleidung, die in anderen Internationalen Normen festgelegt ist (siehe Einleitung).

Vêtements de protection - Vêtements de protection contre la chaleur et les flammes - Exigences de performance minimales (ISO 11612:2015)

L'ISO 11612:2015 spécifie les exigences de performance relatives aux vêtements de protection fabriqués avec des matériaux souples, conçus pour protéger le corps de l'utilisateur, sauf les mains, contre la chaleur et/ou les flammes. Pour la protection de la tête et des pieds, les seuls articles d'habillement de protection relevant du domaine d'application de l'ISO 11612:2015 sont les guêtres, les cagoules et les couvre-chaussures. Toutefois, en ce qui concerne les cagoules, aucune exigence n'est donnée pour les visières et les appareils respiratoires.
Les exigences de performance fournies dans l'ISO 11612:2015 sont applicables aux vêtements de protection qui pourraient être portés pour un large éventail d'utilisations finales, où il existe un besoin de vêtements offrant des propriétés de propagation de flamme limitée et où le porteur peut être exposé à une chaleur émise par rayonnement, par convection ou par contact ou à des projections/éclaboussures de métal en fusion.

Varovalna obleka - Obleka za varovanje pred toploto in plamenom - Minimalne zahtevane lastnosti (ISO 11612:2015)

Ta mednarodni standard določa zahtevane lastnosti za varovalne obleke, izdelane iz prožnih materialov, ki so namenjene zaščiti telesa uporabnika, razen rok, pred vročino in/ali ognjem. Edina varovalna obleka za zaščito uporabnikove glave in stopal, ki sodijo v področje uporabe tega mednarodnega standarda, so gamaše, kapuce in prevleke za obutev. Vendar pa za kapuce niso podane zahteve za vizirje in dihalno opremo. Zahtevane lastnosti, določene v tem mednarodnem standardu, veljajo za varovalne obleke, ki bi jih lahko nosili za širok nabor končnih uporabnikov, kjer obstaja potreba za obleke z omejenimi zmožnostmi širjenja plamenov in kjer je uporabnik lahko izpostavljen toplotnemu sevanju, konvekcijski ali kontaktni toploti ali pljuskom raztopljene kovine. Ta mednarodni standard ne velja za varovalne obleke, ki so opredeljene z drugimi mednarodnimi standardi (glej uvod).

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.

Introduction

The purpose of this International Standard is to provide minimum performance requirements for

clothing to protect against heat and flame, which could be worn for a wide range of end uses. All the

other standards listed in this Introduction deal also with clothing to protect against heat and flame, but

rather for quite specific products or end uses.

Within many of the hazards listed in this International Standard there are three performance levels:

— Level 1 to indicate exposure to low risk;
— Level 2 to indicate exposure to medium risk;
— Level 3 to indicate exposure to high risk.

For protection against extreme exposures to radiant heat, there is a fourth performance level to take

into account, high performance materials such as aluminized and similar materials. The level of personal

protection to be provided is based on the outcome of the risk assessment and some comments on risk

assessment are given in Annex D.

For complete protection against exposure to heat and/or flame, it is probable that 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.

[[[1]]]

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. It is one of several standards for clothing that have been

developed to protect persons against heat and/or flames. Other standards include:

— ISO 11611, Protective clothing for use in welding and allied processes;

— ISO 11613, Protective clothing for firefighters — Laboratory test methods and performance

requirements;

— ISO 14460, Protective clothing for automobile racing drivers — Protection against heat and flame —

Performance requirements and test methods;

— ISO 15384, Protective clothing for firefighters — Laboratory test methods and performance

requirements for wildland firefighting clothing;

— ISO 15538, Protective clothing for firefighters — Laboratory test methods and performance

requirements for protective clothing with a reflective outer surface;

— EN 469, Protective clothing for firefighters — Performance requirements for protective clothing for

firefighting;

— EN 1486, Protective clothing for fire-fighters — Test methods and requirements for reflective clothing

for specialized fire fighting;

— EN 13911, Protective clothing for firefighters — Requirements and test methods for fire hoods for

Protective clothing — Clothing to protect against heat and
flame — Minimum performance requirements
1 Scope

This International Standard specifies performance requirements for protective clothing made from

flexible materials, which are designed to protect the wearer’s body, except the hands, from heat and/or

flame. For protection of the wearer’s head and feet, the only items of protective clothing falling within

the scope of this International Standard are gaiters, hoods, and overboots. However, concerning hoods,

requirements for visors and respiratory equipment are not given.

The performance requirements set out in this International Standard are applicable to protective

clothing which could be worn for a wide range of end uses, where there is a need for clothing with

limited flame spread properties and where the user can be exposed to radiant or convective or contact

heat or to molten metal splashes.

This International Standard is not applicable to protective clothing that is specified by other International

Standards (see Introduction).
