Abstract Overload faults of resistors and power components inside electrical and electronic equipment will generate high‑temperature heat sources. High temperature contacting surrounding plastic insulating parts may bring fire‑ignition safety risks. The IEC 60695‑2‑10 Glow Wire Test Method is a general fire‑hazard test standard formulated by the International Electrotechnical Commission....
Abstract High‑amplitude, short‑duration voltage spike transient interferences will be generated during load switching and relay on‑off of aircraft power busbars. These interferences couple into airborne electronic equipment through AC/DC power input ports and may result in component damage, program abnormality and communication interruption. As a critical EMC test item for airworthiness veri...
Abstract: With the rapid development of new‑energy, rail‑transport, communication and medical‑electronics industries, an increasing number of devices adopt DC power supply mode. Transient voltage dips, short interruptions, voltage rise and fluctuations at DC power ports may cause device reboot, data loss, control‑logic disorder and even hardware damage. IEC 61000‑4‑29 and its correspon...
Abstract During actual operation of public power grids, power quality disturbances such as voltage dips, short interruptions and gradual voltage variations may occur due to line faults, start‑stop of large‑scale equipment and switching operations. Such grid anomalies can directly cause shutdown, data loss, functional disorder, restart or even hardware damage of electrical and electronic produc...
Abstract In the actual operating environment of electrical and electronic equipment, spatial radio‑frequency electromagnetic fields couple through power cables and various signal cables to generate conducted disturbance signals, which may result in abnormal operation, functional failure or even hardware damage of equipment. IEC 61000‑4‑6 and its Chinese equivalent standard GB/T 17626.6‑201...
Abstract Electrostatic discharge (ESD) represents a critical safety hazard for electric and electronic detonators used in civil explosive applications. Improper electrostatic exposure may trigger accidental initiation, functional damage or timing deviation of electro‑explosive devices (EEDs). With the release of revised EN 13763‑13:2025 standard, significant updates have been introduced for ...
Abstract: With the continuous tightening of global environmental regulations, the export of electrical and electronic products requires hazardous substance screening, alloy composition identification and coating thickness measurement. The x ray fluorescence machine has become an important device for industrial quality inspection due to its advantages of non-destructive testing, rapid measurement ...
Abstract: Salt mist corrosion is a major cause of failure for metallic materials and coatings in coastal and industrial environments. The salt mist test chamber can artificially replicate a saline atomized environment to conduct accelerated corrosion tests, providing an important experimental method for evaluating material protection performance. Taking the LISUN YWX/Q‑010 salt mist test chambe...
Abstract: During the operation of electrical and electronic equipment, faults such as circuit short‑circuit and aging overheating of components can easily generate tiny flames, which may ignite surrounding insulating plastics, housing materials and become a major cause of electrical fires. The needle flame test apparatus evaluates the flame‑resistance performance of product components and ins...
