溢出羽流的热通量和温度几乎随室外火灾 HRR 线性增加。

因此,通过调整总火灾HRR,可以匹配立面热通量、羽流温度和点火高度的值,以便在不同测试之间进行公平比较。

这项独特的数值工作探索了不同标准测试的等效立面火灾场景,可以指导未来的立面防火测试开发和优化。

ISO13785-1中尺寸防火测试标准适用范围

This part of ISO 13785 specifies a screening method for determining the reaction to fire performance of products and construction of facades or claddings when exposed to heat from a simulated external fire with flames impinging directly upon a fa?ade. It is intended for use by producers to reduce the burden of testing in Part 2 of ISO 13782 by eliminating those systems that fail the tests described in this part of ISO 13785.

This test method is applicable only to facades and claddings that are not free standing and that are used as an addition to an existing external wall.

This test method also is only applicable to vertical elements and is not applicable to determining the structural strength of the facade or cladding.

美标NFPA285防火性能测试-铝塑复合板NFPA 285耐火窗洞口燃烧测试 https://www.fire-test.cn/newsinfo/2400648.html

南京睿督协助国内铝复合板厂家成功通过美标NFPA 285耐火窗洞口燃烧测试,具体请咨询158-2729-0669。

幕墙产品的防火性能测试根据美标NFPA285进行测试。

NFPA285测试主要参数为:

1. 起火楼层以上两个房间的着火情况,尤其是第三层;

2. 起火房间沿以上2.5m和5m处的温度是否超过500度

3. 是否造成外墙面的大面积垮塌;

4. 对相邻建筑物的影响(通过温度观察);

5. 起火房间、其他楼层房间、墙面、窗沿等处的温度变化情况。
