GB/T 18380.31-2008
AbolishedTest on electric and optical fibre cables under fire conditions - Part 31:Test for vertical flame spread of vertically-mounted bunched wires or cables - Apparatus
电缆和光缆在火焰条件下的燃烧试验 第31部分：垂直安装的成束电线电缆火焰垂直蔓延试验 试验装置
Application Summary AI generated
This standard specifies the design and construction requirements for the test apparatus used to evaluate the vertical flame spread of bunched wires or cables mounted vertically. It is applied in the electrical and optical fibre cable industries to ensure consistent testing conditions for assessing fire propagation in cable bundles. The standard is critical for manufacturers and testing laboratories conducting fire safety certifications for cables used in buildings, tunnels, and industrial installations.
