The radiant flooring panel apparatus consists of a radiant panel, a flooring sample holder, and a control unit. The radiant panel is a flat, rectangular panel that is heated by an electric element. The flooring sample holder is a metal frame that holds the flooring sample in place above the radiant panel. The control unit is used to control the temperature of the radiant panel and to measure the critical radiant flux and smoke production rate of the flooring material.
This machine is suitable for the flammability test of various wire and cable insulation coating materials, printed circuit board materials, IC insulators and other organic materials. During the test, the test piece is placed on the top of the flame, burned for 15 seconds, extinguished for 15 seconds, repeated After 5 times, the test piece is incinerated, and the burning, extinguishing time and repetition times can be set, and the operation can be performed automatically.
Textile flammability is not a simple function, where the 'burning behaviour' of the material can be predicted under all circumstances. The subject is complex; and has resulted in the development of a wide spectrum of test methods, some of which are specific to particular end-uses.
The Single Wires & Cables Vertical Flammability Tester is an essential tool for testing the flammability of wires and cables. The International Electrotechnical Commission (IEC) has set the standard for this test, which is IEC60332. The purpose of this test is to ensure that the wires and cables used in electrical and electronic equipment meet certain fire safety standards.
The horizontal combustion tester is applicable to the measurement of relative combustion rate, flame retardance and horizontal combustion performance of various textile fabrics, clothing, tents, etc., especially automotive interior fabrics.
