Abstract In modern industrial production, accurate color detection and consistent color control are crucial links affecting product quality. With the continuous upgrading of industrial intelligence, portable color detection equipment has become the preferred tool in various fields due to its flexibility and efficiency. The LISUN HSCD-860 handheld spectrophotometer, independently developed by LISUN...
Abstract: Leakage current serves as a core metric for evaluating the integrity of insulation systems and electric shock protection in electrical equipment. Throughout a product’s lifecycle, whether in precision electronic devices or high-power household appliances, abnormal fluctuations in leakage current often indicate potential safety hazards. This paper aims to conduct an in-depth analysi...
Abstract: In the global conformity certification of consumer electronics, household appliances, and lighting equipment, preventing human contact with hazardous live parts represents the core requirement of safety design. The articulated test finger, serving as a standardized detection tool that simulates human finger contact behavior, is crucial for verifying the effectiveness of enclosure protect...
Abstract: In electronic engineering and environmental reliability evaluation systems, the Ingress Protection (IP) rating is an internationally recognized standard for measuring products’ defense capabilities against solid foreign object intrusion. The dust test machine, as the core experimental platform for verifying IP5X (dust-protected) and IP6X (dust-tight) ratings, derives its technical ...
Abstract: In modern industrial manufacturing and quality assurance frameworks, ensuring reliable environmental adaptability for electrical and electronic equipment is a prerequisite for accessing global markets. As the internationally accepted criterion for evaluating enclosure protection ratings (IP codes), the IEC 60529:2013 standard provides a rigorous technical framework for IPX5 (water jet) a...
Abstract: In the optical characterization of transparent and translucent materials, optical scattering phenomena serve as core metrics for evaluating material clarity and purity. However, confusion frequently arises between the concepts of “turbidity” and “haze” across industrial and academic communities. This paper aims to provide an in-depth analysis from the dual perspec...
Abstract: Under high-current fault conditions, the insulating materials in electrical and electronic equipment often face fire risks initiated by arcing. High Current Arc Ignition (HAI), as a core metric for evaluating the arc resistance of materials, has criteria whose accuracy directly impacts the electrical safety design of products. This article aims to provide an in-depth analysis of the ques...
Abstract: Withstand voltage testing, also known as high insulation strength testing, is a core method for evaluating the safety of electrical equipment, electronic instruments, and insulating materials. By applying a voltage higher than the rated operating voltage of the equipment, the withstand voltage test aims to verify whether the insulation system possesses sufficient electrical strength to w...
