Scope

This document describes a series of laboratory ignition sources used for fire testing of plastics and products primarily composed of plastics, and classifies them. These ignition sources vary in intensity and impact range, simulating the initial thermal abuse that plastics may face in certain real-life fire risk scenarios. This document describes the ignition sources used in different standards (methods, specifications, or protocols) to evaluate the combustion performance of plastics and plastic-containing products. The ignition sources in this document are related to flaming and non-flaming ignition methods. The ignition sources described in this document refer to relevant standards. This document does not discuss the standards that reference these ignition sources, and it may not include all ignition sources. This document does not address detailed experimental steps.
