Plastic Combustibility Tester, UL 94, ASTM D 5048, ASTM D 3801, ASTM D 4804, ASTM D 4986, ISO 10351,ISO 1210, ISO 9772,3, IEC 707
UL 94 measures the combustion properties (after flame, after glow) by burner (H-5025 UL tirrill burner) when test sample combusts in chamber's internal volume of 0.864㎥ and is installed internal light to observe the specimen's properties and has ventilating opening with emission fan to remove the combustion gas.
FESTEC's UL 94-AVH has auto specimen moving system for protecting user from hazardous gas and auto burner moving system for meeting the whole test standards. This auto burner moving system has a goniometer, so it can change the angle of flame to the specimen (0˚, 20˚, 30˚, 45˚, 90˚).
Control box and remote controller  help user to handle this eqipment or check after flame time and after glow time during testing and are able to adjust the angle.
