The LISUN JL-UL UL Environment Test Equipment Water Spray Head Piping Test is manufactured in strict accordance with a series of international authoritative standards. It can accurately simulate rainy weather conditions and conduct comprehensive tests on the physical properties and other related performances of various products. This paper will conduct an in-depth analysis of the design standards, structural composition, and technical parameters of this equipment, elaborate on its role and application process in product testing, and demonstrate its significant value in ensuring product quality and promoting the standardized development of the industry by combining actual data and diagrams. It aims to provide a reference for product design, improvement, verifi...
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 product design optimization. This paper takes the LISUN SC-015 Dustproof Testing Machine (Sand Dust Chamber) as the research object, systematically elaborates on its application scope, compliance standards, structural design, technical specifications, and test implementation methods. Through detailed analysis of its functional characteristics and practical application value, this paper aims to provide a comprehensive reference for researchers and engineers engaged in product dustproof performance testing and quality control. 1.

Abstract Against the backdrop of the rapid development of the semiconductor industry, the problem of damage to semiconductor devices caused by electrostatic discharge (ESD) has become increasingly prominent. The Human Body Model (HBM) and Machine Model (MM) are the main sources of electrostatic threats faced by semiconductor devices during production, transportation, and use. This article focuses on the LISUN ESD-883D Electrostatic Discharge Simulator (HBM/MM), elaborating in detail on its design principles, compliance with international and domestic standards, equipment features, specifications, and applications in ESD susceptibility testing of semiconductor devices such as LED chips, transistors, and ICs. Through a comprehensive analysis of this equipment, this article demonstrates its important role in ensuring the quality and reliability of semiconductor devices, providing a reference for relevant testing work in the semiconductor industry. Keywords Electrostatic Discharge Simulato...
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 components. This paper focuses on the surge test generator as a core tool for evaluating the surge tolerance of these components, with a specific analysis of the LISUN SG61000-5 Surge Generator. By adhering to international standards such as IEC 61000-4-5, this equipment provides a unified and reliable basis for surge immunity testing. Experimental data from tests on typical power cables and internal connectors are presented to verify the effectiveness of the surge test generator in identifying vulnerability points and guiding product optimization. 1. Introduction Electromagnetic Compatibility (EMC) i...
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 behavior. The experiments were conducted using the LISUN ZRS-3H Glow-wire Test Apparatus, which complies with international standards including IEC 60695-2-10 and UL 746A. Three representative materials—glass fiber-reinforced polycarbonate (PC-GF30), polybutylene terephthalate (PBT-GF30), and polyethylene terephthalate (PET-GF30)—were tested under controlled conditions. Results indicate that PC-GF30 exhibits the highest GWIT (825°C) and GWFI (900°C), followed by PBT-GF30 (GWIT: 725°C; GWFI: 800°C) and PET-GF30 (GWIT: 675°C; GWFI: 750°C). The LISUN ZRS-3H apparatus demonstrated high precision in ...
