Abstract Glow wire flammability testing is a critical evaluation method for assessing the fire safety of polymeric materials used in lighting devices, electronic products, and household appliances. This study aims to systematically investigate the glow wire flammability performance of common engineering plastics, focusing on ignition temperature (GWIT), flammability index (GWFI), and combustion be...
Abstract Fire and flammability testing plays a critical role in ensuring the safety of electrical equipment and combustible materials, as small flames resulting from internal faults can trigger catastrophic fire hazards. The LISUN ZY-3 Needle Flame Test Apparatus is a specialized instrument designed to simulate such fault-induced small flames and evaluate ignition risks. This paper elaborates on t...
Abstract Conducted radio frequency (RF) immunity testing is a critical component of electromagnetic compatibility (EMC) compliance, ensuring electronic equipment operates reliably in RF-polluted environments. This paper focuses on the CDNE for Conducted RF Immunity test, with a specific analysis of the LISUN CDNE-M316 Coupling and Decoupling Network. The CDNE-M316, designed to meet CISPR 15:2018 a...
Abstract With the widespread application of DC-powered electronic and electrical equipment in fields such as industrial control, automotive electronics, and renewable energy systems, the stability and reliability of these devices under abnormal power supply conditions have become crucial. Voltage dips and short interruptions at the DC power input port are common electromagnetic disturbance scenari...
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...
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 f...
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 equipme...
Abstract This paper focuses on the significance of ISTA and ASTM Drop Test Machines for packages, with a particular emphasis on the LISUN DT-60KG Automatic Double – Arms Drop Test Machine. It elaborates on how these machines measure the impact that packages endure during transportation and handling processes, such as drops. By conducting relevant tests, the impact strength of packages can...
Abstract Alloy analysis is critical in industries such as manufacturing, automotive, aerospace, and waste metal recycling, as it ensures material quality, safety compliance, and resource efficiency. Traditional alloy analysis methods (e.g., laboratory-based atomic absorption spectroscopy or inductively coupled plasma mass spectrometry) are limited by their bulkiness, high cost, and requirement for...
