Network HC Hardware: 4 quarter of 2008, Trade and Industry Bureau in Chengdu, Chengdu, marketing part of the electrical heating device for monitoring the quality of goods, monitoring of key security-related properties for access to live parts protection, input power and current, operating temperature and electrical leakage current strength, leakage current and electric strength, stability, and mechanical hazards, power connection and external flexible wire, grounding measures 12 projects have been tested. Monitoring results show that the quality heater is not optimistic.

Unqualified project's main issues and reasons:

1. Signs and instructions failed. 15 samples failed the project logo and description, mainly heater failure or warnings on the signs describing incomplete. Logo incomplete, that is, the characteristics of the product itself can not be unmistakably told to users, easily lead to misuse of products and professional service because they do not harm.

2. Input power and current failure. The spot checks, 10 samples of input power and current non-compliance. This project is basically substandard products are less than standard power range, power is not enough as the heater will affect the results, take longer to achieve the purpose of heating, the consumer will consume more electricity, the environmental protection energy saving is also negative. The reason is that an enterprise in order to reduce the production cost of quality used parts for second lowest result.

3. Power connection and external flexible cord failed. The spot checks, 19 samples do not meet standards. The main problems is that the power cord and standard deviation for the nominal cross sectional area of the larger and the lack of equipment between the power cord connector. Sectional area of the power cord is not enough heat will cause large amount of work, affecting the life of the power cord, resulting in decreased wire insulation, easily lead to leakage accident. Connecting line between lack of cord will affect the safety of electrical use.

4. Grounding measures failed. The spot checks in the grounding of 17 products do not meet standards. Ground connection is to prevent the event of insulation failure, it can protect the product easy to touch metal parts will not leak, a solid and reliable ground connection required. If ground is not solid, then the failure occurs when the electrical insulation, can not leak through the ground wire leads, making it easy case charged, causing electric shock. The reason is the manufacturers assembly process is not strictly enforce the rules, the standard factory test fails strictly to the project.

Sum up, the heater products mainly due to some random unqualified manufacturers of quality consciousness, to reduce costs, optional accessory quality second lowest result.

For sampling results, Industry and Commerce has notified the city's stores and all kinds of household appliances appliance electrical products distribution business will be disqualified immediately from shelves and stop selling to protect people's use of safety appliances for heating in winter
