Abstract: The burst tester is a high-precision device core to the field of electromagnetic compatibility (EMC) immunity testing. Its core value is to simulate high-frequency burst interference encountered by electrical and electronic equipment in actual working conditions, evaluate equipment immunity performance, and serve as a key testing tool to ensure stable operation in complex electromagnetic...
Abstract: Safety testing of electrical products is a critical step to ensure product quality and operational safety. Traditional testing methods require multiple separate instruments, leading to cumbersome processes and low efficiency. The LS9956 Automatic Electrical Safety Tester developed by LISUN is an integrated electrical safety inspection system that realizes the one‑stop integration of fi...
Abstract: As core equipment for material weatherability testing, the Xenon Lamp Accelerated Aging Chamber adopts “natural environment simulation + accelerated aging” as its core design principle. Through the cooperation of full-spectrum xenon arc lamps and multi-environment control modules, it accurately simulates and accelerates the natural outdoor aging process of materials. Taking the LISUN...
Abstract IEC 60529 IPX3/IPX4 Testing establishes the definitive methodology for evaluating enclosure protection against sprayed water in luminaire applications. This comprehensive analysis examines five critical engineering parameters governing the oscillating tube test apparatus configuration, including spray nozzle geometry, water flow rates, rotational kinematics, and sample mounting protocols....
Abstract To address the fundamental question of what is temperature calibrator, this study examines the critical role of precision thermal sources in modern metrology, specifically focusing on infrared thermometer verification systems. Temperature calibrators serve as reference standards that enable traceable measurements linking field instruments to international temperature scales. This paper pr...
Abstract How does an XRF analyzer work? This fundamental question addresses the core mechanism behind one of the most reliable non-destructive testing methodologies in modern materials science. X-ray fluorescence (XRF) spectrometry enables rapid, in-situ elemental analysis through the interaction of primary X-ray excitation with atomic electron shells, producing characteristic secondary emissions ...
Abstract Hipot tester technologies represent critical instrumentation for verifying dielectric integrity across electrical manufacturing sectors. This study systematically examines the technical principles, compliance frameworks, and engineering design requirements of AC/DC withstand voltage testing equipment capable of delivering up to 5kV output. Through analysis of IEC 61010-1, UL 506, and GB 7...
In 2026, the Bureau of Indian Standards (BIS) completed and issued the revised standard IS 16102-2:2026 for the operational performance of outdoor LED lighting equipment. As a core mandatory standard for India’s outdoor LED lighting sector, this update further refines technical requirements and improves test specifications on the original basis. It aims to enhance the reliability, safety, and ad...
On February 24, 2026, the Bureau of Indian Standards (BIS) officially released the revised safety standard for self-ballasted LED lamps for general lighting, IS 16102-1:2026, which replaces the 2012 version. It specifies that the transition period for the old and new standards will last until August 2, 2026, after which the old standard will be formally abolished. As the core mandatory safety stan...
