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.

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 14, Fire-fighters’ personal equipment.
ISO 11999 consists of the following parts, under the general title PPE for Firefighters — Test methods and
requirements for PPE used by firefighters who are at risk of exposure to high levels of heat and to flame while
fighting fires occurring in structures:
— Part 1: General
— Part 2: Compatibility
— Part 3: Clothing
— Part 4: Gloves
NOTE The number of this draft has been changed from ISO/DIS 11613-2 to ISO 11999-2. The committee
agreed a new number for this project was appropriate given the scope publication of the ISO 11999 series was to
cover ensemble standards. It was further agreed that ISO 11613:1999 would remain current.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 11999-2:2013(E)
PPE for firefighters — Test methods and requirements
for PPE used by firefighters who are at risk of exposure
to high levels of heat and/or flame while fighting fires
occurring in structures —
Part 2:
Compatibility
1 Scope
This part of ISO 11999 describes compatibility for ensembles of firefighters’ personal protective
equipment (PPE) to be used by firefighters who are at risk of exposure to high levels of heat and/or
flame while fighting fires occurring in structures.
This part of ISO 11999 includes methods for compatibility testing in laboratories and procedures for
compatibility testing to be performed by wearers.
NOTE Where the presence of more than one risk to health and safety makes it necessary to wear or use
more than one item of PPE simultaneously, it is important that such equipment is compatible and continues to be
effective against the risk(s) in question.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3.4
practical performance test
test procedure with wearers of PPE ensembles moving under specified conditions
3.5
performance test
test procedure with PPE ensembles in laboratories under specified conditions
4 Compatibility
4.1 General
Compatibility becomes an issue when different types of PPE of an ensemble are worn at the same time.
This is because each type of PPE may interfere with another type of PPE. This may lead to a reduction
of protection provided by the PPE and/or other restrictions, which may cause a limitation of the tactical
mission. The main hazards of structural firefighting are impacts of heat and flame. Furthermore the
penetration of water may cause severe injuries during structural firefighting.
For items of PPE to be marked as compatible according to ISO 11999-1, they shall also meet the relevant
performance requirements specified in this part of ISO 11999. Practical performance testing should be
carried out in accordance with Annex A.
NOTE Additional information on compatibility can be found in ISO/TR 21808.
4.2 Minimum requirements of compatibility
Compatible items of PPE (of the types described in ISO 11999-3 and ISO 11999-4) shall meet the
performance requirements of Clause 4.
Compatible items of PPE shall meet the relevant requirements of this Clause, thereby showing that they
fit together and function together.
Compatible items of PPE shall not cause impairments for the wearer while being worn.
Compatible items of PPE shall not cause restrictions of the protection level when used in an ensemble.
4.3 Fit and function tests demonstrating compatibility
Test subjects perform a series of practical tests (practical performance tests) that demonstrate the
compatibility of items of PPE and ensembles measured against a set of performance criteria.
4.3.1 Test subjects
A minimum of three test subjects shall be chosen, one male, one female. Each subject shall be an
experienced firefighter, appropriately trained, and medically checked. The items of PPE evaluated shall
be the appropriate size and correctly fitted for the firefighter.
It is important that a test subject is wearing all items of PPE when testing the compatibility for fit
and interface of only a few specific items. These may not be directly adjacent to a specific item being
considered in the test; however, this item of
