Abstract Salt fog test is a core accelerated environmental detection method to evaluate the corrosion resistance of metal coatings, paint films and complete electronic products. The cavity corrosion resistance, temperature and humidity control accuracy and automatic functions of the salt fog test chamber directly affect the stability of test data. Taking the LISUN YWX/Q-010 salt fog test chamber a...
Abstract Glow wire testing serves as a core fire safety detection method to simulate ignition of surrounding non-metallic materials triggered by overheated components inside electrical and electronic products. The accuracy of test conditions directly determines the effectiveness of flame retardancy evaluation. Taking the LISUN ZRS-3H glow wire tester as the research object, this paper illustrates ...
Abstract: What is hipot testing used for is a frequently raised core question in the electrical manufacturing and testing & certification industry. Hipot testing, also known as dielectric strength test, applies AC/DC high voltage higher than the rated operating voltage to electrical products while monitoring breakdown leakage current. It evaluates the insulation withstand limit of the device u...
Abstract: Lightning-induced overvoltage and transient shocks caused by switching of large-capacity loads on power grids may damage the power and communication ports of electronic equipment. The lightning surge test is a mandatory test item to verify the electromagnetic immunity performance of electrical and electronic products. As core standard equipment for lightning surge test, the LISUN SG61000...
Abstract: For lighting products such as LED lights, plant grow lights, outdoor street lights and floodlights exported overseas and applied in engineering projects, complete spatial light distribution data is essential. As a globally universal standard data carrier for luminaire light distribution, IES testing documents serve as core technical files for lighting simulation, product certification an...
Abstract: With the high-frequency and integrated development of electronic products, conducted and radiated electromagnetic interference generated by switching power supplies, motor drives and other modules continues to intensify. Electromagnetic Compatibility (EMC) has become a mandatory threshold for product launch and export certification. As core instruments to quantify interference and locate...
Abstract Products are continuously subjected to complex climatic stresses such as low temperature, high temperature, high humidity and alternating dry-wet conditions during natural service, storage and transportation, which may easily lead to performance degradation, structural failure and insulation damage. The temperature and humidity chamber can accurately reproduce various extreme and cyclic t...
Abstract Conventional single-function color temperature meters can only display the correlated color temperature of light sources. They fail to fully analyze comprehensive light quality indicators including light source spectrum, color rendering, flicker and blue light hazard, making it difficult to meet high-precision testing requirements in various industries such as LED lighting, display techno...
Abstract Overheating of heating elements such as resistance wires and motor windings during the operation of electrical equipment continuously transfers high temperature and ignites surrounding solid insulating and combustible materials. Such non-flame thermal conduction fire scenarios cannot be evaluated by the needle flame test method, and dedicated hot wire ignition testing is required to quant...
