Introduction
This vertical horizontal wire flame test equipment (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.
Main advantages
1, The cabinet is assist with upper and lower two sections, it would be easy to move into test room;
2, Touch-screen control system, convenient for operation;
3, 6 test program for selection;
4, Burner angle can be moved automatically.
