 China Quality News Network News provisions under the "Product Quality Law of the People's Republic of China", the product quality supervision and spot checks, the Guangdong Provincial Bureau of ac dc power supply Quality and Technical Supervision of electric bicycles, cell phone chargers, mobile phone batteries, power adapter (with an uninterruptible power supply ), badminton, massage equipment, treadmills, skates, knives, scissors, satellite positioning vehicle traveling data recorder, GPS navigator, casual wear, home textile products (including bedding), RMB detectors, computers, color TV,usb to power adapter 20 kinds of products the special supervision of the Tablet PC, set-top boxes, LED lights and light controller, video surveillance and Protection (variable speed ball machine). 


 

The sample of 40 batches of Shenzhen, Huizhou, Dongguan, Switching Power Adapter Zhongshan and other 37 enterprises in the production of power adapter (including uninterruptible power supply), test failed seven batches of substandard products found was 17.5%. 

 

The sampling based on GB 4943-2001 the safety of information technology equipment, GB 8898-2001 "Audio, video and similar electronic apparatus - Safety requirements" switching mode power supply GB 4943.1-2011 "information technology equipment", GB 8898-2011 "audio , video and similar electronic apparatus - Safety requirements "GB 9254-2008" information technology equipment Radio disturbance characteristics - Limits and measurement methods, GB 13837-2003 "Sound and television broadcast receivers and associated equipment - Radio disturbance characteristics - Limits and methods of measurement ", switching mode power adapter GB / T 14715-1993" Information technology equipment uninterruptible power supply for general technical conditions "and by the filing of corporate standards or products expressly technical requirements, markings and instructions of the information technology and telecommunications terminal products with the power adapter components ( line plug size and torque), electric shock and energy hazards, electrical insulation, electrical clearance / creepage distances and insulation penetration distance, wiring / connection, resistant to abnormal heat, touch current and protective conductor current and electric strength, power supply terminal conduction disturbance voltage, to radiation disturbance field strength of 11 projects have been tested, audio and video equipment with a power adapter marking and instructions for use, the risk of electric shock against electric shock structure requirements, under normal operating conditions, clearances and creepage distance, insulation resistance and dielectric strength, terminals, electrical connections and fixed machinery, power supply terminal conduction disturbance voltage disturbance power nine projects have been tested. 

 

The spot checks found that 7 batches of product failure, related to the components (line plug size and torque), markings and instructions, wiring / connection resistance, abnormal heat, power terminal disturbance voltage projects.
