Standards Development

Scope

This document describes and classifies a range of laboratory ignition sources for use in fire tests on plastics and products consisting substantially of plastics. These sources vary in intensity and area of impingement. They are suitable for use to simulate the initial thermal abuse to which plastics are potentially exposed in certain actual fire risk scenarios.

Different standards developing organizations have issued many standard test methods, specifications and regulations to assess fire properties of plastics or of products containing plastic materials. Many of those standards contain ignition sources associated with flaming and non-flaming ignition. This document describes the ignition sources and references the associated standard.

This compilation of ignition sources does not discuss the application of the standard where the ignition source is described and is likely not to be a fully comprehensive list of ignition sources. This document does not address detailed test procedures.

Purpose

This is a proposal to convert ISO/TR 10093:2018 into a full international standard, i.e. ISO 10093. WG 8 considered the fact that the ignition sources described in ISO/TR 10093:2018 are needed for various other ISO documents, including some under the jurisdiction of this SC. If ISO/TR 10093:2018 remains a technical report it cannot be included as a normative reference and the ignition sources described in it cannot be required to be complied with.
