德国Wazau DIN53438烟密度测试仪     原装进口DIN4102烟密度试验仪

烟密度测试仪满足DIN53438和DIN4102等相关标准，用单燃烧室检验测定密度。适用于所有塑料、橡胶、纺织品覆盖物、喷涂表面、木材及其他建筑材料等的测试。

将厚度不超过25mm的试样（扁形材料、合成材料或装配品）水平放置在密封的试验箱里，在有或没有阴引燃火焰的前提下，对试样施加一定的热量辐射，测量裸露表面产生的烟气量。

The Wazau Smoke density testers Combustion Behavior Test Equipment

according to DIN 4102 B2 and DIN 53438

Purpose and Application

1.This standard specifies a method for the determination of the behaviour of normal flamable building materials when exposed to the flame of a burner acc. to DIN 50051 part 1 (DIN EN ISO  6941)  under  defined  conditions.  This  test  procedure  is  suitable  for  controlling  the similarity of products with respect to behaviour when exposed to flames and for comparing the product. In addition to this the test results may give hints to the combustion behaviour of materials in praxis.

The behaviour of materials against impact of flames depends in reality among others of the thickness of the product. Therefore if is advisable to execute the test according to this standard with specimen of different thickness.

2. Brief description of the procedure

A vertically arranged specimen, which is placed in the burning cabinet, will be exposed to a defined flame either at the lower edge (K = edge-flaming) or in the middle of the lower half of the sample (F = surface-flaming). The purpose of the procedure is the determin, whether and in which time the top of the flame reaches a defined mark on the specimen.

3. Specimen (sample)

Five each specimen are produced for each procedure.

Procedure K: specimen 190 mm length and 90 mm width Procedure F: specimen 230 mm length and 90 mm width
