Plastics - Guidance for the use of standard fire tests (ISO/DIS 10840:2025)
ISO 10840:2008 covers the following aspects of fire testing of plastics materials and products:
selection of appropriate tests that reflect realistic end-use conditions;
grouping of the reaction-to-fire characteristics that any given test or tests can measure;
assessment of tests as to their relevance in areas such as material characterization, quality control, pre‑selection, end-product testing, environmental profiling and DfE (Design for the Environment);
definition of potential problems that may arise when plastics are tested in standard fire tests.
The scope of the standard does not include the development or design of new fire tests for plastics. However, the flexibility of approach that is indicated with respect to the mounting and fixing of test specimens will be valuable when fire-testing laboratories and certification bodies are considering how to evaluate ranges of plastics that are used in different ways.

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
