Introduction
This vertical horizontal wire flame test device (VW-1) is designed according to UL1581 sect 1080.1~1080.14, and meets the criteria of VW-1(Vertical-specimen) Flame Test. It can be used to test of 1060 products wire and cable FT1 and vertical burning test,1080 VW-1 test, 1061 test, 1090 horizontal test and 1100 horizontal specimen or FT2 test;to assess the flame spreading ability to combustible near by of cable or flexible wire when it caught fire.The whole test is carried out in a sealed test chamber with a volume of 4.32 M3.
Test method: adjust the flame height to placed the specimen at the top of the flame, burning for 15 seconds, extinguished 15 seconds, repeat 5 times,then inspecting the burned situation of the specimen, it can be set the combustion, extinguish and repetition automaticlly.
