Abstract In the context of global market integration and harmonized technical standards, product safety and environmental durability have evolved from competitive advantages into fundamental requirements for market access. The IEC 60529:2013 standard, published by the International Electrotechnical Commission, is globally recognized for defining Ingress Protection (IP) ratings, providing a system...
Abstract Transient overvoltages and overcurrents caused by lightning strikes and grid switching operations are critical factors threatening the reliability of electrical and electronic equipment. The impulse voltage tester (also referred to as a surge generator) is a core electromagnetic compatibility (EMC) test instrument for simulating such high-energy transient interference and evaluating the ...
Abstract As a key equipment in industrial production, scientific research and testing fields, color measurement instruments directly affect product quality control and R&D efficiency with their measurement accuracy, stability and convenience. Taking the HSCD-860 Handheld Spectrophotometer (High-Precision Reflection) launched by LISUN GROUP as the research object, this paper systematically anal...
Abstract In the system of industrial product R&D, production quality inspection, and compliance certification, the environmental adaptability and reliability of materials and products are core indicators determining their market competitiveness and service life. As a key equipment for accurately simulating complex natural environments, climate chambers can accelerate the assessment of product ...
Abstract In lighting quality assessment, display device calibration, and various light source R&D, color temperature, as a core parameter describing the chromatic characteristics of a light source, is crucial for accurate measurement. The traditional colorimeter offers limited functionality, whereas modern optical measurement technology integrates its capabilities into more powerful portable ...
Abstract How to Perform the Salt Spray Test? This is a core technical question in evaluating the corrosion resistance of metallic materials, coatings, electronic components, and various industrial products. The salt spray test is a standardized test method that uses a sodium chloride solution to simulate marine or salt-laden atmospheric environments, accelerating corrosion to assess a product̵...
Abstract How to do ball pressure test? The Ball Pressure Test is a core safety assessment procedure used to evaluate the thermal deformation resistance of non-metallic components (e.g., insulating materials, enclosures, support parts) in electrical and electronic equipment. It is widely applied in quality control and safety certification for products such as plugs and sockets, luminaires, switches...
Abstract What is the burning test? The burning test, or flame retardance performance test, is the core collective term for a series of standardized experimental methods that scientifically evaluate a material’s reaction characteristics, fire hazard, and safety level under simulated, specific ignition source conditions. For industries such as automotive, rail transportation, aerospace, and co...
Abstract Waterproof performance is a critical determinant of product reliability and lifespan across numerous fields, including consumer electronics, outdoor lighting, household appliances, and automotive components. Within the IP (Ingress Protection) rating system defined by the International Electrotechnical Commission standard IEC 60529 (equivalent to GB/T 4208), IPX1 and IPX2 serve as the foun...
