The glow wire test is a physical experiment. The purpose is to test the stability of electronic and electrical products at work. The glow-wire tester heats the heating wire of the specified material (￠4 Ni80/Cr20) and shape with a large current to the test temperature (550 ℃ ~ 960 ℃) for 1min, and then burns the test sample vertically with the specified pressure (1.0N) for 30s. Determine the...

IK ratings are defined as IKXX, where “XX“ is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against external mechanical impacts. The different IK ratings relate to the ability of an enclosure to resist impact energy levels measured in joules (J). IEC62262 specifies how the enclosure must be mounted for testing, the atmospheric con...
1. The mechanism of EFT Immunity Measurement and its impact on electronic products The EFT immunity tester is a transient disturbance generated at the disconnection due to the insulation breakdown of the switch contact gap or the contact bounce when the inductive load (such as relay, contactor, etc.) is disconnected. When the inductive load is repeatedly switched on and off for many times, the pul...

What is the goniophotometer？ The goniophotometer is the main measuring equipment for the light distribution performance test of lamps, which can be used to measure the spatial light intensity distribution, total light flux and lamp efficiency of lamps or light sources. The goniophotometer system consists of precision turntable and control system, spectrum analysis system, standard lamp, alignmen...
Origin and development of integrating sphere: The use of integrating sphere in measuring luminous flux can be traced back to 1890, and now it has become a widely used instrument in many aspects. The integrating sphere can be used to test the luminous flux, color temperature, light efficiency and other parameters of the light source. It is an indispensable instrument in the measurement of radiance,...
