UL 94 Horizontal and Vertical Flammability Tester with Flame 50W and 500W
Introduction:
The Horizontal-Vertical Flame Tester is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator. It screening procedure for comparing the relative burning behaviour specimens made from plastic and other non-metallic materials ,exposed to a flame ignition source of 50W or 500W nominal power. These test methods determine the linear burning rate and the afterflame/afterglow times,as well as the damaged length of specimens.They are applicable to solid and cellular materials that have an apparent density of not less than 250kg/m3,determined in accordance with ISO845.Then do not apply to materials that shrink away from the applied flame without ignitiong;ISO9773 should be used for thin flexible materials. And it's the combustion test device of plastic materials represented by UL-94. It can perform each test of HB, V0 to V2, 5V and VTM, HBF.
Instrument:
The product adopts the integrating intake ignition system with the combustion delay only 0.1 second so as to ensure the sufficient burning time of the gas; based on the black background and multifunctional flame gauge, the flame adjustment work becomes simple and easy; the whole box body with a large observation window is made of the stainless steel; the imported high-precision digital-display instrument has an artistic shape; it integrates a number of the advantages of the similar products at home and abroad, so it features the stable performance and easy operation. The instrument is designed to conform to the most commonly used standards in the market.
