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

Introduction
The purpose of this document is to provide minimum performance requirements for clothing in order
to reduce the possibility of the clothing and/or its materials burning when in occasional and brief
contact with small flames and thereby, itself constituting a hazard.
For complete protection against exposure to flame, it will be necessary to protect the head, face, hands,
and/or feet with suitable PPE and, in some cases, appropriate respiratory protection might also be
considered necessary.
[5]
Attention is drawn to ISO/TR 2801:2007, which sets out guidelines for selection, use, care, and
maintenance of protective clothing against flame.
Nothing in this document is intended to restrict any jurisdiction, purchaser, or manufacturer from
exceeding these minimum requirements.

4.1 Single layer garments containing limited flame spread index 1 materials, shall be worn over
index 2 or index 3 garments and shall not come into contact with the skin (e.g. in the neck and wrist
ISO/DIS 14116:2023(E)
area). If an assembly contains index 1 materials, those shall not come into contact with the skin (e.g. in
the neck and wrist area).
It shall be verified by visual inspection when the garment is worn by an appropriate user.
4.2 Protective clothing may consist of several separate garments or it may be a single garment with
one or more layers.
4.3 General requirements which are not specifically covered in this document shall be in accordance
with ISO 13688:2013/AMD 1:2021.
4.4 Hardware penetrating the outer material of a protective garment or garment assembly shall not
be exposed to the innermost surface of the garment or the garment assembly.
Conformity shall be checked by visual inspection.
4.5 Where garments are constructed with pockets, the pockets shall be made of material(s)
conforming to 6.1.2 and 6.1.3
4.6 The maximum distance between buttonholes/ press studs shall be 150 mm.
4.7 If zippers are used, they shall be designed in such a way that they completely close the opening
and the slide fastener shall be designed to lock when completely closed.
4.8 Cuffs and lower leg regions of trousers may be provided with closures to reduce their width.
4.9 An outer two piece suit, when correctly sized for the wearer, shall provide an overlap between
the jacket and trousers which remains when one standing wearer firstly fully extends both arms above
the head and then bends over until the fingertips touch the ground. In addition, the wrists and lower
arms shall also remain covered in an upright position with arms hanging down; this shall also apply to
one piece suits.
5 Sampling, pre-treatment, and ageing
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 in Clause 6. Samples for testing shall be taken from the original garment or shall be
representative of the component assembly.
5.2 Pre-treatment of material
Before each test specified in Clause 6, the test materials and test specimens shall be pre-treated by
cleaning. If the manufacturer’s instructions indicate that cleaning is not allowed, then testing shall
be carried out on new material. In addition, 6.1 requires that the limited flame spread tests shall be
carried out both before the pre-treatment and after the pre-treatment.
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 manufacturer. If the garment can be washed and dry-cleaned, it shall only be washed. If
ISO/DIS 14116:2023(E)
only dry-cleaning is allowed, the garment shall be dry-cleaned in accordance with the manufacturer's
instructions.
NOTE Manufacturer’s instructions typically indicate one or several of the various methods and processes of
[3] [4] [6]
ISO 6330:2021, ISO 15797:2017, ISO 3175-2:2017, or equivalent as standardized processes for cleaning.
5.3 Ageing
In case the garment should be submitted to some treatment to maintain its limited flame spread
property as specified in Clause 7, 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 Clause 7 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 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) %. Testing shall be carried out within 5 min of removal from this
atmosphere.
6 Performance requirements
6.1 Limited flame spread performance
6.1.1 Limited flame spread index quoted shall be the lowest value determined either before or after
pre-treatment specified in 5.2.
6.1.2 All single layer materials used in a single layer garment claiming compliance with this document
shall achieve a limited flame spread index of 1, 2, or 3 (see Clause 7) when tested in accordance with
ISO 15025:2016 Procedure A (surface ignition), before and after the pre-treatment in accordance with
Clause 5. The flame shall be applied to the outer face.
6.1.3 All material assemblies and multilayer materials claiming compliance with this document
shall achieve a limited flame spread index of 1, 2, or 3 (see Clause 7) when tested in accordance with
ISO 15025:2016 Procedure A, before and after the pre-treatment.

accordance with ISO 15025:2016 with the flame applied to the outer face and index 2 or index 3
with the flame applied to the inner face of the assembly (in this case, additional sets of specimen
are needed).
b) Or, each layer of a material assembly shall comply with index 1, index 2 or index 3 when tested with
the flame applied to the outer face, except the innermost layer which shall comply with index 2 or
index
