BS 8434-2 Methods of test for assessment of the fire integrity of electric cables-Part 2: Test for unprotected small cables for use in emergency circuits - BS EN 50200 with a 930 °C flame and with water spray

BS 8434-2电缆防火完整性评估的测试方法，第2部分：应急电路中使用的无防护型小电缆的测试，BS EN 50200火焰温度为930°C和水雾

 

 

BS 8434-2该标准规定了一种用于小型无保护电缆的测试方法，其中BS EN 50200的要求被修改为使用(930+40)'C的火焰温度和水雾的应用。使用此方法证明符合BS 5839-1要求。

 

Scope:

This British Standard specifies a method of test to be used for small unprotected cables where the requirements of BS EN 50200 are modified to use a flame temperature of (930+40)'C and the application of water spray. Compliance with the requirements of BS 5839-1:2002, 26.2e) may be demonstrated using this method.
