Flammability Testing Equipment for Fire hazard testing

The IEC60112 specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The IEC60695 series, under the general title fire hazard testing. This series of standards that make available standardized test flames covering a range of powers for the use of all product committees needing such test flames. A needle flame is described in IEC 60695-11-5, a 500 W flame is described in IEC 60695-11-3,a 50 W flame is described in IEC 60695-11-4, and a 1 kW flame is described in IEC 60695-11-2. IEC 60695 also gives recommendations with regard to the glow-wire test apparatus. We have produced many models for the fire hazard testing. Including Tracking test equipment, Glow Wire test equipment, Horizontal and Vertical test equipment, Needle Flame test equipment.

Helium Leak Testing Equipment For Condenser And Evaporator

The Helium Leak Detection System is specially designed for leak test Condenser, Evaporator, Automobile radiator, Engine cooler, switch gears, and it is the most efficient industrial-scale Automatic Leak Testing Equipments for Heat Exchangers in Market. The system is able to run the following tests: Leak detection with pressure decay method to find Gross Leaks. Helium test with mass spectrometer to find Fine leaks. Features: PLC control, touch screen display All automatic leak testing with over all leak test Non operator dependent Back ground suppression technology, ensure precise testing Automatic digital pass/Fail indication. Ensure operation reliability The chamber helium leak test system proposed has the totally automatic cycle with manual load and unload of the tested piece. The Test Cycle can be described in the following way: Manual load of the tested piece in the Test Chamber. Closure of the Chamber. Evacuation of the Chamber to a value of vacuum suitable for Leak Test with Mass Spectrometer. During the evacuation of the Chamber, the system will run the following Tests on the tested piece: Pressure decay to reveal Gross Leaks; Tested piece evacuation; Reaching a vacuum value suitable for transfer, that is to put the mass spectrometer in communication with the Test Chamber. Reading of background, which is the residual Helium in the Test Chamber. Pressurization of tested piece with Helium. Leak test with Mass Spectrometer. Ventilation of the Test Chamber (return to atmospheric pressure), Helium Recovery from tested piece. Opening of the Chamber Manual unloads of tested piece.

Sniffer Type Helium Leak Detection System for Air conditioner heat exchanger

The Systems manufactured by HeJin use Helium as tracing gas for detecting leaks. This test allows measuring the defined the leak position on the component/test piece. In this case the Test piece to Be Tested is connected to the helium filling joint. Then the Test piece are pressurised with helium. Tracing gas come out from test piece through leaks and is detected and measured by sniffer connected to Helium Mass Spectrometer. The system proposed has a totally automatic cycle with manual load and unload of the Test pieces. The Test Cycle can be described in the following way: Manual connect the test piece to the helium filling joint. Pressurization of test pieces with nitrogen. Pressure decay to reveal gross leaks; Pressure discharge and test pieces evacuation; Pressurization of test pieces with helium. Manual leak test with sniffer detector. Helium recovery from test pieces. Manual unload the test piece.
