UNI 8456  Combustible Materials Which Can Be Hit By Flame On Both Surfaces - Reaction To Fire By Applying A Small Flame

UNI  8456  受双面火焰燃烧的易燃材料-小火焰

本规范描述了一种测定试样燃烧时间、阴燃时间、损坏区域和滴落的方法，试样的下边缘受到小火焰的作用。本规则适用于所有在其使用中垂直悬挂或在任何情况下可能同时被火焰击中的产品。本规则不适用于在EN 13501-1中定义的测试方法适用的建筑产品。该方法为产品在火灾早期在小型火源作用下的火灾反应提供了指导。

 

This standard describes a method for determining the post-combustion time of post-combustion of the post-combustion time, the damaged area and the dripping of a test tube subjected to the action of a small flame applied to its lower edge This standard is applicable to all products which are in their intended use Suspended vertically or which, in any case, may be flamed on both sides simultaneously This standard shall not apply to construction products for which: Test methods defined in UNI EN 13501-1.

 

The method provides an indicative indication of the reaction to fire of a product in the initial stage of a fire, under the action of a limited-volume ignition source.
