Testing corrosion resistance is an essential demand in marine hardware, industrial hardware, metal surface finishes, connector housing, electro-plated parts, valves and in coated automotive hardware. In such applications, the corrosion process does not have an immediate effect; it develops slowly by a combination of atmospheric moisture, ionic contaminants and oxygen. In long periods of time under...
One of the most expensive and disruptive faults that have occurred in electrical systems is the insulation failure. Regardless of the application and the utility transformers, switchgear assemblies, rotating motors, GIS panels, surge arrestors or distribution relays, irrespective whether the dielectric systems have failed, this is reporting directly to extended outages, fire hazards, damaged equip...
Environmental sealing is increasingly important in the manufacture of electrical, mechanical, automotive, and outdoor industrial products in order to be functional and safe. Since dust is a major pollutant during the field deployment in the harsh conditions of desert, mining, roadside installation, textile processing or agricultural zones, it is important to ensure that equipment can withstand exp...
Professional lighting evaluation requires correct measurement of luminous distribution and beam shape, light intensity distribution, uniformity and directional output. In current illumination systems, total lumens are no longer a significant consideration and rather accurate angular distribution of light is used to establish compliance, visual comfort, energy efficiency and harmonious beam in prac...
In November 2025, a severe fire in Tai Po, Hong Kong, filled people’s hearts with profound sorrow. Amid the roaring flames, textiles inside the building, such as curtains, carpets and decorative fabrics, burned rapidly. The toxic smoke released and the fast-spreading blaze not only narrowed the escape routes but also posed immense challenges to the rescue operations. This tragedy serves as a...
The high rate of development of solid-state lighting has generated the demand of precise and dependable luminous flux measurements. To develop energy-saving LED systems, the optical output, color stability, heating impacts and reality lumen depreciation have to be evaluated accurately. The most common method of this measure is one found on an integrating sphere which is an optical enclosure that i...
Abstract Accurately assessing the quality of electronic capacitors is fundamental to ensuring the reliability and performance of electronic devices. This article systematically details the critical parameters, technical principles, and methodologies involved in how to measure capacitance and, by extension, overall capacitor quality. It provides an in-depth introduction to the series of capacitor m...
The ingress protection testing has been significantly changed in the past 10 years with the push of industries among outdoor-rated electronics, sealed industrial controls, marine-rated automation, and battery-powered equipment. The IPX5 level is one of the commonest waterproof levels that are very practical in real-life applications in consumer electronics, lighting, outdoor power equipment, wall-...
Abstract With the rapid development of new-energy technologies, the battery—being the core component of energy storage—has attracted increasing attention for its performance verification techniques. Among them, the Battery Tester serves as the key instrument for battery inspection and plays an irreplaceable role in quality control, maintenance and R&D. Taking the LISUN LS5562 Battery Teste...
