The flammability test usually refer to needle flame test chamber , horizontal vertical flame test and glow wire test . And glow wire test is carried out by heating circuit, no need to be ignited by gas. For needle flame test chamber , the methane with purity of not less than 98%.  Is used. For IP Test Spary Nozzle  of V - 0, V - 1 or V - 2, 5VA, 5VB class material, the gas is methane, over 98%  purity. For flammability test of HF - 1, 2 - HF or H B F class foam material, the gas is methane, with not less than 98%  purity and 37+ 1MJ/m3 calorific value . For single cable vertical flame test conform to IEC60332, propane and air mixed gas is applied. For horizontal vertical flame test, should use methane not less than 98%  purity.

LED  lamp has various shapes, for example the fluorescent lamp tube type LED , same as ordinary fluorescent lamp , power module and a light emitting diode are sealed inside fluorescent tube shaped transparent polymer shell which also provide fire and electric shock prevention . According to the requirements of UL standards, the shell material of energy-saving lamp shall reach at least V - 1 flame resistance level  which is determined by UL94 Burning  Glow wire test apparatus Zhilitong Electromechanical Co., Ltd supply UL94 Burning Tester  ZLT- UL94  which can carry out the test flame power 50W and 500W combustion test

According to IEC 61643 clause 6.2.9, insulating materials necessary to retain live parts in their position shall be composed of non-tracking materials, or they shall have sufficiently diementioned. Testing is in accordance with IEC 60112, solution A with a test voltage 175 V. Zhilitong Electromechanical Co., Ltd manufactures   textile testing equipment   ZLT-LDQ1, which is meeting with IEC 60112 standard and can proforma tracking test with test voltage range 0-600 V.

According to IEC 62115 clause 19.2 , for electric toys , parts of non-metallic material are subjected to the glow wire test apparatus of IEC 60695-2-11 , which is carried out at 550°C But , parts of insulating material supporting connections carrying a current exceeding 3A and having a working voltage exceeding 12V, and parts of insulating material within a distance of 3 mm of such connection, are subject to the glow wire test apparatus  of IEC 60695-2-11 at a temperature of 650°C  . The glow wire test apparatus ZLT-GTR made by Zhilitong Electromechanical Co., ltd, can perform glow wire test at temperature 5 50 °C , 650 °C, 750 °C and  850 °C.

According to IEC 60669 clause 20, switches ,boxes and screwed glands of switches that have an IP code higher than IP0 shall have adequate mechanical strength so as to withstand the stresses imposed during installation and use. Compliance is checked by the following test: For all types of switches and their dedicated box , are subject to   IP Test Spary Nozzle   with striking elements mass 150±1g  Zhilitong Electromechanical Co., Ltd provides   I K Pendulum Impact Tester  ZLT-BC3  which can provide both high impact energy and low impact energy from 2J up to 50J .
