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

This first edition of ISO 13506-1, together with ISO 13506-2, cancels and replaces the first edition of
ISO 13506:2008, which has been technically revised. The assessment of skin burn injury has been
transferred to ISO 13506-2.

Introduction
The purpose of heat and flame-resistant protective clothing is to shield the wearer from hazards that
can cause skin burn injury. The clothing can be made from one or more materials. The evaluation of
materials for potential use in this type of clothing generally involves two steps. First, the materials
are tested to gauge their ability to limit flame spread. They are then tested to determine the rate of
transferred energy through them when exposed to a particular hazard. A variety of test methods are
used in these two steps. The test method selected depends on the nature of the potential hazards and
the intended end use of the materials. Once suitable materials have been identified, they can be made
into complete garments or ensembles for testing on a manikin-fire exposure system.
Laboratory bench scale transferred energy tests are used to select suitable materials for a protective
clothing ensemble. While these tests can allow ranking of garment or ensemble materials and
components, the tests do not allow a complete assessment of a garment or ensemble made of the
materials.
Bench scale transferred energy test methods use small amounts of material, up to 150 mm × 150 mm in
area, and hold the material initially flat, either in a vertical or horizontal plane. Multiple layers are used
where appropriate (e.g. fire-fighting ensembles). In this case, the layer normally worn on the exterior
is exposed directly to the energy source, while the layer normally worn on the inside is away from the
energy source. With the planar orientation and alignment of materials, shrinkage has little effect on the
outcome of
