There is a problem with the accessories that will cause the entire electric tool to be returned

Recently, the inspection and quarantine bureau of Zhangzhou found in the retrospective investigation of returned goods that the export quality of an electric tool exporting enterprise in the area was not in conformity with the standard requirements for the accessories of the rechargeable electric drill, and the flame retardancy of the insulation material of the charging stand and the battery pack fixed live parts was poor, resulting in the The entire cabinet of the batch of products was returned for repair.

It is understood that this enterprise is a foreign trade enterprise that mainly produces rechargeable electric tools. Its annual export volume is nearly 15 million yuan. The trading countries are mainly EU. Although the person in charge of the company attaches great importance to the quality of finished products, even a rechargeable electric tool testing laboratory has been set up in the company to strengthen the design review. However, this time it neglects to attach importance to the quality of accessories.

The outlets of rechargeable electric tools are generally package-based. In addition to the power tool itself, adapters, battery packs, and charging stations are also included. According to the standards, in addition to the IEC 60745 system, the electric tools exported to the European Union must be compliant with the IEC 60335 standard system, as part of the charger kit, charging stand, and battery pack (when charging, forming a loop). IEC 60335-1:2001+A1:2004+A2:2006, paragraph 30.2.3 clearly states that: when it is an unattended device during work, the insulating material part supporting the connector that carries more than 0.2 A during normal operation shall pass through at least 850 degree glow wire test. However, because the company did not understand the standard requirements of accessories, it ignored the quality control of the charging seat and the battery pack fixed charged parts materials, because the insulating material did not pass the glow wire test, the flame retardant characteristics did not meet the standards and led to customer requests for return repair, to The company has brought greater losses. After the inspection and quarantine authorities understand the situation, they will promptly instruct the company to analyze the standards of the accessories and explain the quality requirements of the importing country for key components (such as the IEC 60335 standard system, packaging requirements for battery packs and other dangerous goods). At the same time, enterprises are reminded to strengthen the quality control of the production of accessories and to prevent the recurrence of such problems from the production process and process.

This is a typical example of a finished product return due to an incomplete fitting. The hidden dangers of flame-retardant performance of insulating materials for charging seats and battery packs with fixed live parts are relatively common in small and medium-sized power tools. Exporters of a large number of electric tools in Ningbo area do not understand the relevant standard requirements for key accessories. For this reason, the inspection and quarantine department reminds export enterprises of electric tools that they should firmly establish themselves as the first person responsible for product quality, strengthen the collection, sorting, and learning of relevant standards for key accessories and strengthen the quality control of accessories. At the same time, SMEs with relatively weak technological capabilities should rely on inspection and quarantine technical forces to collect relevant standards and strengthen internal control to ensure product quality and safety.
