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, and by Technical Committee CEN/TC 162, Protective clothing including
hand and arm protection and lifejackets in collaboration.
This third edition cancels and replaces the second edition (ISO 11612:2008), of which it constitutes a
minor revision with the following changes:
— modify clause in design requirements regarding garment overlaps;
— modify clause in design requirements regarding the areas of the body covered by protective suits;
— modify clause on sampling requirements;
— modify clause for ageing due to washing (maximum number of cleaning procedures as indicated by
the manufacturer);
— modify pre-treatment clause to include requirements for single-use garments;
— include new requirement for measuring property value for rating and classification;
— modify requirement for optional heat resistance testing at 260 °C;
— remove reference to melting from flame spread requirements;
— modify afterflame requirement for flame spread;
— modify afterglow requirement for flame spread;
— modify requirement that hardware is tested only after pre-treatment;
— include statement for flame spread testing in regard to interlining materials;
— modify test procedure for the flame testing of labels, badges, and retro-reflective materials;
— modify requirements for tear strength;

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
firefighters;
— EN 15614, Protective clothing for firefighters — Laboratory test methods and performance requirements

INTERNATIONAL STANDARD ISO 11612:2015(E)
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).
