Introduction to Impulse Magnetic Field Immunity Testing In the modern era of increasingly complex electronic systems, ensuring the immunity of devices to electromagnetic disturbances has become critical. One of the most challenging forms of electromagnetic interference (EMI) is the impulse magnetic field, which can cause severe malfunction in sensitive electronic equipment. To address this challen...
The IK Vertical Hammer Impact Tester plays a critical role in evaluating the durability and resilience of electrical and electronic equipment subjected to mechanical impacts, as per international standards such as IEC 60068-2-75. The LISUN IK07-10VT model, designed for vertical impact testing, is a robust piece of equipment widely used in product testing to simulate real-world mechanical stresses ...
Abstract In electrical and electronic industries, ensuring the fire safety of materials used in products is a critical part of product testing and certification. The UL 94 Combustion (Fire) Tests for Plastics is a widely accepted standard to evaluate the flammability properties of plastic materials used in electrical appliances, equipment, and their components. This paper discusses the application...
Abstract This paper explores the application of the LISUN SC-015 Dustproof Testing Machine in assessing the physical and performance characteristics of electronic and electrical products, luminaires, electrical cabinets, electrical components, automobiles, motorcycles, and related parts under simulated dusty environmental conditions. By conducting tests for IP5X and IP6X dustproof standards, manuf...
Introduction Haze and turbidity are critical parameters in evaluating the optical clarity and quality of various materials, including glass, plastic, and liquids. These parameters are particularly significant in industries like automotive, construction, packaging, and pharmaceuticals, where transparency and consistency are vital for functionality and aesthetics. This article explores the concepts ...
Abstract: This paper focuses on the electromagnetic compatibility (EMC) testing of power cords and internal connectors in the context of high energy transient interference caused by natural lightning surge induction and large capacity load switching. The LISUN SG61000-5 Surge Generator is introduced as a key tool for conducting such tests. The working principle, specifications, and application sce...
Uncertainty and Errors When measuring physical quantities like length, weight, or time, mistakes can occur during the measuring process, affecting the results. These mistakes are called errors. Errors can be caused by various factors, such as faulty measuring tools, human error in reading measurements, or issues with the measurement system. For example, if a thermometer is malfunctioning and shows...
Abstract: XRF fluorescence, or X-ray fluorescence, is a non-destructive analytical technique used to determine the elemental composition of materials. By analyzing the characteristic wavelengths emitted by different elements when exposed to X-rays, instruments like the LISUN EDX-2A RoHS Testing Equipment provide precise and reliable results. This paper delves into the principles, applications, and...
Due to the various types and appearances of large luminaires, such as LED street lights, floodlights, panel lights, etc., it is difficult to fix the luminaires in a traditional integrating sphere when doing 4π testing. Because there is no test base (platform) to hold so heavy LED outdoor lighting fixtures. LISUN IS-*MA Optical 4π Geometry Integrating Sphere With Holder Base is designed for th...
