Test or certification item 测试或认证名称:  受双面火焰燃烧的易燃材料-对火反应通过将小火焰
Combustible Materials Which Can Be Hit By Flame On Both Surfaces - Reaction To Fire By Applying A Small Flame

 

Test or certification info 测试和认证相关内容:

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.

辐射板和引燃火焰被点燃。然后对燃烧器和垂直定向的试样进行定位。记录到达不同标记线程的时间。计算平均速度以达到火焰传播速度。观察到损坏区域以及滴落和燃烧的碎片。根据对火焰蔓延、受损区域以及滴落和燃烧碎片的观察，可以对材料进行分级。

The radiant panel and pilot flame are ignited. The burner and the vertically oriented specimen are then positioned. The time to reach the different marker threads is recorded. The average velocity is calculated to reach the flame spread velocity. The damaged zone and dripping and flaming debris are observed. Based on the observations of flame spread, damaged zone and dripping and flaming debris, the material can be classified in levels.



这些级别乘以一个因子。火焰蔓延速度x2，损坏区域x2，余辉时间x1，墙壁滴水x1，天花板滴水x2。行为水平的总和乘以修正系数得出产品类别（I至IV）。

The levels are multiplied with a factor. Flame spread velocity x2, Damaged zone x2, After-glow time x1, Dripping x1 for wall and x2 for ceiling. The sum of the levels of behaviour multiplied by the correction factors give the products category (I to IV).
