欧洲家具EN 597-1 跟EN 597-2两个阻燃标准一样吗?
2022-06-11 08:34:00 【中科易朔】
EN 597-1 跟EN 597-2 测试原理不一样哈,两个标准都是测定床垫和软床等家具的燃烧性能,但是点火源不一样。EN 597-1点火源是香烟阴燃,EN597-2点火源是火柴火焰。
EN597-1 Furniture – Assessment of the ignitability of mattresses and upholstered bed bases – Part 1: Ignition source smouldering cigarette./ EN597-1 家具 - 床垫和软床具燃烧性能评定第1部分点火源:阴燃香烟
EN 597-2 Furniture – Assessment of the ignitability of mattresses and upholstered bed bases – Part 2: Ignition source match flame equivalent./ EN 597-2 家具 - 床垫和软床具燃烧性能评定第2部分点火源:火柴等同火焰
名词解析:
渐进式闷烧:
放热氧化,不伴随有燃烧,即自蔓延,独立于火源,可能伴随也可能不伴随白炽
测试原理:
EN 597-1:
要求床垫,床具或床垫衬垫一个完整朝上表面遭受点燃香烟的阴燃处理,所有不同特征的区域都要进行测试。
EN 597-2:
要求床垫,床具或床垫衬垫一个完整朝上表面遭受火柴等同火焰气体火焰的明火燃烧处理,所有不同特征的区域都要进行测试。
火焰:
在气态状态下燃烧并发出光的火焰
可燃性:
一种材料、产品或部件被点燃以燃烧或逐渐阴燃的容易程度
软体家具定义:
软体家具主要指的是以海绵、织物为主体的家具。软体家私的制造工艺主要依靠手工工艺,主工序包括钉内架、打底布、粘海绵、裁、车外套到最后的扪工工序。例如沙发、床等家具。软体家私属于家私中的一种,包含了休闲布艺、真皮、仿皮、皮加布类的沙发、软床。
