Protective clothing - Clothing to protect against heat and flame - Minimum performance requirements (ISO 11612:2015)
ISO 11612:2015 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 ISO 11612:2015 are gaiters, hoods, and overboots. However, concerning hoods, requirements for visors and respiratory equipment are not given.
The performance requirements set out in ISO 11612:2015 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.
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).

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

4.5 Additional design requirements for molten splash protective garments
Garments that are designed to protect against the risk of exposure to molten metal splash by meeting
the performance requirements designated by code letters D and E, shall have the following additional
design features.
a) The sleeves of jackets and coveralls and the lower leg regions of trousers, coveralls and bib and
brace shall not have turn-ups.
b) External pockets on jackets, trousers, coveralls, and bib and brace, other than side pockets below
the waist which do not extend more than 10° forward of the side seam, shall be covered by flaps at
least 20 mm wider than the opening of the pocket (at least 10 mm on each side) in order to prevent
the flap from being tucked into the pocket.
c) Patch pockets shall be made from materials meeting the same protection indices (chosen from A to
F) and the same levels for these indices as the rest of the garment.
d) Overlapping seams on the outside of the garment shall be downward facing and secured in this
position.
e) Closures shall be designed with a protective cover flap on the outside of the garment. The maximum
distance between buttonholes/press studs shall be 150 mm. If zippers are used, the slide fastener
shall be designed to lock when completely closed. Cuffs may be provided with closures to reduce
their width. The closure and any fold which it creates shall be on the underside of the cuff. Cuffs
shall not have turn-ups. Neck openings shall be provided with closures. Trousers may have side slits
which shall have a means of closure and the slit and closure shall be covered.
f) Pleats in the exterior surface of the garment can act as trapping points for hot/molten materials.
If pleats are present in the garment, the bottoms of the pleats shall incorporate a means whereby
entrapment of molten metal can be prevented, for example by incorporating diagonal stitches or
some other feature.
Conformity to a), d), and f) shall be checked by visual inspection and b) and e) by visual inspection and
physical measurement.
NOTE Further guidance on design of clothing to protect against these risks is given in Annex C.
5 Sampling and pre-treatment
5.1 Sampling
The number of samples and the size of the specimens of garment materials or garments presented to
the different test methods, shall be in accordance with the respective test standards specified in the
requirements Clauses 6 and 7. Samples for testing shall be taken from the original garment or shall be
representative of the component assembly.
5.2 Pre-treatment
5.2.1 Pre-treatment by cleaning
Before each test specified in Clauses 6 and 7, except 6.6, the test materials and test specimens shall
be pre-treated by cleaning. If the manufacturer’s instructions indicate that cleaning is not allowed, i.e.
single-use garments, then testing shall be carried out on new material. In addition, 6.3 requires that
the limited flame spread tests shall be carried out both before the pre-treatment and after the pre-
treatment, if cleaning is allowed.
The cleaning shall be in line with the manufacturer’s instructions, on the basis of standardized processes.
If the number of cleaning cycles is not specified, the tests shall be carried out after five cleaning cycles (a
cleaning cycle is one wash and one dry cycle). This shall be reflected in the information supplied by the
6 © ISO 2015 – All rights reserved
ISO 11612:2015(E)
manufacturer. If the garment can be washed and dry-cleaned, it shall only be washed. If only dry-cleaning
is allowed, the garment shall be dry-cleaned in accordance with the manufacturer’s instructions.
Leather materials shall be tested in the new state, except if the manufacturer indicates that cleaning is
allowed. In that case, cleaning shall be carried out according to the manufacturer’s instructions.
The test specified in 6.6 shall be carried out in the new state (as received).
NOTE Manufacturer’s instructions typically indicate one or several of the various methods and processes of
[2] [3] [5]
ISO 6330, ISO 15797, ISO 3175-2, or equivalent as standardized processes for cleaning.
5.2.2 Mechanical pre-treatment
Metallized materials shall be pre-treated in accordance with Annex A before being submitted to radiant
heat testing (see 7.3).
5.3 Ageing
In the case that the garment should be submitted to some treatment to maintain its limited flame spread
property as specified in 6.3, the manufacturer shall indicate the maximum number of cleaning cycles
that can be carried out before applying the treatment indicated to maintain the garment protective
performance. Limited flame spread test according to 6.3 shall be carried out after the last cleaning
cycles before any treatment as indicated by the manufacturer; in both cases the garment shall comply
with the requirement.
5.4 Conditioning
Specimens other than leather shall be conditioned for at least 24 h in an atmosphere having a temperature
of (20 ± 2) °C and a relative humidity of (65 ± 5) %. Leather specimens shall be conditioned for at least
48 h in an atmosphere having a temperature of (20 ± 2) °C and a relative humidity of (65 ± 5) %. Testing
shall be carried out within 5 min of removal from this atmosphere.
6 General performance requirements
6.1 General
Protective garments that comply with this International Standard shall meet the requirements of
Clause 6, with the exception of the requirements of 6.2.2, which is optional, and shall meet at least one of
the heat transmission requirements for letter codes B, C, D, or F of Clause 7 based on their intended use.
Such garments shall be marked in accordance with Clause 8.
Wherever in Clauses 6 and 7, the requirements for a property value are expressed in terms of a minimum
or maximum value, and wherever a minimum or maximum value is to determine a Level or Class for that
property, the resultant property value shall be determined according to Annex B. All tests results in
Clauses 6 and 7 shall be evaluated in accordance with Annex E.
6.2 Heat resistance
6.2.1 Heat resistance at a temperature of (180 ± 5) °C
All materials and hardware, including retro-reflective materials used in the garment and/or clothing
assembly shall be tested according to ISO 17493 at a temperature of (180 ± 5) °C for an exposure time
of 5 min. Materials can be either tested separately or as assembled in the garment and/or component
assembly. Test samples shall not ignite or melt, and fabrics and leather also not shrink by more than 5 %.
To verify shrinkage on multilayer samples, it might be necessary to close by sewing around the edges of
the test samples. At least 5 min after completion of the test, it shall be verified that the closure system
can be opened at least once.
