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...
Abstract:With the acceleration of global industrialization, the ability of electronic, automotive, and lighting equipment to withstand extreme climatic conditions has become a core measure of product quality. The IEC 60529:2013 standard, globally recognized as the benchmark for evaluating Ingress Protection (IP Code) ratings, strictly defines the test conditions for IPX5 (water jets) and IPX6 (pow...
Abstract Salt spray corrosion is one of the main environmental factors leading to the failure of metal materials and various industrial products. The global economic loss caused by salt spray corrosion reaches hundreds of billions of US dollars every year. As a core testing equipment for simulating salt spray corrosion environments, the salt fog test machine can quickly evaluate the corrosion resi...
Abstract As an efficient and accurate element analysis equipment, the metal XRF analyzer plays a crucial role in industrial testing, environmental monitoring and other fields relying on its unique working principle. Taking the LISUN EDX-2A energy dispersive X-ray fluorescence spectrometer as the research object, this paper elaborates in detail the core principle of the metal XRF analyzer for deter...
Abstract How to perform a leakage current test? This is a core technical question that must be answered when assessing the safety performance of various electrical products such as household appliances, lighting equipment, and medical instruments. Leakage current testing, or touch current testing, aims to quantitatively evaluate the current intensity that could potentially flow through a human bod...
Abstract What does an RF current probe measure? This is a fundamental question concerning a core technique in Electromagnetic Compatibility (EMC) testing. An RF current probe is a non-contact sensor specifically designed to measure radio-frequency interference currents, particularly common-mode interference currents, flowing in wires or cables, typically within the frequency range of 9 kHz to 300 ...
