引言

在考虑使用本部分的试验方法时，重要的是要区分“制成品试验”与“预选试验”的差别。制成品试验

是对一台完整产品、零件、元件或组件进行的着火危险评定试验。预选试验则是对材料(零件、元件或组

件)进行的燃烧特性试验。

材料的预选试验通常使用标准形状的试验样品，如长方形的条状试验样品或长方形的试验样板，并

常常用标准模制工艺制备。

须要强调的是使用本部分给出的预选试验的数据要认真考虑，以确保对预期应用的适用性，避免错

用和错误地理解。一个零件或一台产品的实际着火性能受其周围环境、设计参数如形状和大小、制造工

艺、传热效果、潜在引燃源的种类及与其接触时间的长短等的影响。重要的是要牢记，这些特性可能还受

可预见的用途、不正确的使用和环境暴露情况的影响。

预选法的优点有以下几点:

a)在做成标准试样试验时，反应较好的材料，在做成产品零件
