描述
UL94 Horizontal-Vertical FlammabilityTester 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 behavior 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 after flame/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 ISO 845. Then do not apply to materials that shrink away from the applied flame without ignition; ISO 9773 should be used for thin flexible materials. And 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.
Standards:
UL94: Test for Flammability of Plastic Materials forParts in Devices and Appliances
GB / T2408: Plastic – Determination of burningcharacteristic – Horizontal and Vertical Test
ISO9722: Cellular plastics — Determination ofhorizontal burning characteristics of small specimenssubjected to a small flame
ASTM D4986: Standard Test Method for HorizontalBurning Characteristics of Cellular PolymericMaterials
IEC60695-11
Features:
Horizontal and vertical flammability chamber is composed by the test part and control part, using the integrateddesign, to facilitate the installation at the scene and debug. The shell of the test chamber and the important partsare all manufactured by stainless steel, resistant cigarettes and gas corrosion. The automatic degree of controlsystem is high. Has automatic ignition, the products which were tested in both vertical and horizontal orientationhas the function automatically follow flame in the cross of the test. Time and temperature figures show, so thatthe observation and records is facilitate and the use of it is stable and reliable.
