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 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/or flame
while fighting fires occurring in structures:
— Part 1: General
— Part 2: Compatibility [Technical Specification]
— Part 3: Clothing
— Part 4: Gloves
— Part 5: Helmets
— Part 6: Footwear
— Part 9: Fire hoods
NOTE The number of this draft has been changed from ISO 11613-9 to ISO 11999-9. 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.

Part 9:
Fire hoods
1 Scope
This part of ISO 11999 specifies the minimum design and performance requirements for a fire hood
as part of personal protective equipment (PPE) to be used by firefighters, primarily but not solely to
protect against exposure to flame and high thermal loads.
