Abstract Dust intrusion is a major threat to the reliability and service life of products in industries such as electronics, electrical engineering, and automotive manufacturing. The sand dust test chamber serves as a critical tool to simulate dusty environmental conditions, evaluate product dustproof performance, and verify compliance with industry standards. This paper focuses on the LISUN SC-010 Sand Dust Test Chamber, a representative device designed for testing the physical and functional performance of electronic and electrical products, lamps, electrical cabinets, electrical components, and automotive/motorcycle parts under simulated dust climates. It elaborates on the chamber’s compliance with IP5X and IP6X dustproof rating standards (per IEC 60529), technical specifications, test procedures, and practical applications. By analyzing test data and case studies, this paper confirms that the LISUN SC-010 Sand Dust Test Chamber provides accurate, repeatable results, supporting prod...
Abstract The flammability test for plastics is a fundamental assessment in material science and product safety, particularly for components used in electrical and electronic appliances. Among various testing methods, the glow-wire test stands out for its ability to simulate thermal stresses caused by overheated or glowing parts in equipment. This paper explores the glow-wire test as a physical thermal flammability test for plastics, detailing its principles, procedures, and applications. The focus is on the LISUN ZRS-3H Glow-Wire Test Apparatus, an instrument designed to evaluate the ignition susceptibility, ignition temperature, flammability, and flammability index of plastic materials. The discussion includes experimental data and comparative analysis to underscore the test’s relevance in ensuring compliance with international safety standards. Glow wire tester Introduction Plastics are ubiquitous in modern industries, especially in lighting devices, electronics, and household applia...
Abstract With the rapid development of electronic and electrical systems, especially in the aerospace and military fields, the demand for reliable Electromagnetic Compatibility (EMC) testing equipment has become increasingly urgent. Voltage spike, as a typical electromagnetic interference (EMI) signal, can easily cause malfunctions or even permanent damage to sensitive electronic devices. The 600V Voltage Spike Generator, represented by the LISUN DO160-S17 model, is a core device designed to simulate such voltage spike interference and verify the EMC performance of Equipment Under Test (EUT). This paper takes the LISUN DO160-S17 600V Voltage Spike Generator as the research object, systematically introduces its working principle, detailed technical parameters, structural design characteristics, and practical application scenarios in compliance with international standards such as RTCA DO-160 Section 17 and MIL3-DO-160-S17. Through the analysis of its performance indicators and test proc...
Abstract In the modern electronic landscape, electromagnetic compatibility (EMC) has emerged as a critical factor ensuring the reliable operation of electronic devices in diverse electromagnetic environments. Damped oscillatory magnetic field immunity testing, guided by the IEC 61000-4-10 standard, plays a vital role in evaluating a device’s ability to withstand damped oscillatory magnetic field disturbances. This paper focuses on the LISUN DOMF61000-10 Damped Oscillatory Magnetic Field Immunity Tester, a specialized equipment designed for conducting IEC 61000-4-10 Oscillatory Immunity Testing. It provides a detailed examination of the tester’s design, specifications, working principle, and application scenarios. By analyzing the key parameters and performance indicators of the DOMF61000-10, this paper aims to demonstrate its significance in meeting the requirements of IEC 61000-4-10 Oscillatory Immunity Testing and ensuring the EMC performance of electronic products. 1.

Abstract With the rapid development of industrial electronics and power systems, electromagnetic compatibility (EMC) has become a critical criterion for ensuring the stable operation of electrical and electronic equipment. Damped oscillatory wave interference, a common electromagnetic disturbance in power grids and industrial environments, can cause malfunctions or even damage to sensitive equipment. The IEC 61000-4-18 Slow and Fast Damped Oscillatory Wave standard specifies the testing and measurement techniques for evaluating equipment immunity to such interference. This paper takes the LISUN DOW61000-18 series Damped Oscillatory Wave Immunity Tester as a case study, systematically analyzing the technical background of the IEC 61000-4-18 standard (including slow and fast damped oscillatory wave requirements), the design principles of damped oscillatory wave generators, and the technical specifications and application scenarios of the LISUN DOW61000-18 series. Through detailed paramet...
