Abstract In environments where electronic and electrical products, automotive components, and lamps operate, dust accumulation and infiltration often lead to performance degradation, functional failures, or shortened service life. The dustproof testing machine, as a core equipment for simulating dust climate conditions, plays a crucial role in verifying product dustproof performance and guiding pr...
Abstract With the increasing complexity of electrical and electronic systems, the reliability of power supply lines and internal connecting cables under transient interference has become a critical concern. Natural lightning-induced surges and high-capacity inductive-capacitive load switching can generate high-energy transient disturbances, which may cause irreversible damage to sensitive componen...
Abstract Salt spray corrosion, as one of the most destructive forms of atmospheric corrosion, poses a severe threat to the durability and reliability of metal materials and their protective coatings in harsh environments such as marine, automotive, and industrial settings. To address the challenges of evaluating corrosion resistance efficiently, salt spray test chambers have become indispensable e...
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...
