This random inspection focused on 10 items, including anti electric shock protection, structural requirements, moisture resistance, insulation resistance and electrical strength, temperature rise, fluorescent lamp load test, mechanical strength, heat resistance, creepage distance, electrical clearance and sealant penetration distance, as well as the resistance to abnormal heat, fire, and electrical tracing of insulation materials This spot check covered large, medium, small, and micro enterprises, with a total of 8, 11, 40, and 108 enterprises sampled. Spot checks have found quality issues in the products of two micro enterprises, Shijiazhuang Xinnai Electrical Appliances Co., Ltd. and Wenzhou Longyang Electrical Appliances Co., Ltd. Among them, two unqualified items were detected for the concealed rocker type dual circuit switch with public access line produced by Shijiazhuang Xinnai Electric Appliance Co., Ltd., namely the creepage distance, electrical gap, and sealant penetration distance, as well as the heat resistance project. The unqualified problem is manifested in the indentation diameter greater than 2mm during the 125 ℃ heat resistance test; When the sample contacts are separated, the electrical gap between the separated live parts is less than 3mm. After analysis by the technical organization, the main reasons for product quality issues are: firstly, the internal structural design of the product is unreasonable, resulting in the electrical gap between the live parts assembled on the switch product not meeting the standard requirements; The second reason is that recycled materials may be used in the raw materials of the plastic parts of the product, resulting in substandard heat resistance performance. The creepage distance, electrical gap, and sealant penetration distance of the concealed rocker type dual control switch produced by Wenzhou Longyang Electrical Appliance Co., Ltd. are not qualified, as shown in the electrical gap between the separated live parts when the sample contacts are separated being less than 3mm. After analysis by technical institutions, the main reason for product quality issues is that the components used by the enterprise did not meet the requirements of the design drawings, resulting in the electrical gap between the live parts assembled on the switch product not meeting the standard requirements
