本文件提供了适用于由塑料制成或包含塑料的半成品和成品的中等规模防火试验的开发和使用指南和要求。 本文件涵盖了此类试验的典型应用，以及试样的制备和安装方法。 本文件适用于平面、线性或异型塑料产品。这些产品可以在水平或垂直方向上进行测试。 本文件定义了待测量的参数、预计报告测试结果的方式，并解释了如何将其用于直接产品评估或作为规模研究的输入数据。

This document provides guidelines and specifies requirements for the development and use of intermediate-scale fire tests applicable to semi-finished and finished products made of, or containing, plastics. This document covers typical applications of such tests, as well as methods of preparation and mounting of test specimens. This document applies to planar, linear or profiled plastics products. These products can be tested in horizontal or vertical orientation. This document defines the parameters to be measured, the way that test results are expected to be reported and explains how they can be used for direct product assessment or as input data for scaling studies.
