Concern Hardware & Electrical Industry 2008 Top Ten contest, click to enter>>>>
Network HC Hardware: four quarter of 2008, Trade and Sector Bureau in Chengdu, Chengdu, marketing and advertising component of the electrical heating device for monitoring the good quality of goods, monitoring of crucial security-associated properties for access to reside components protection, input power and existing, operating temperature and electrical leakage current strength, leakage current and electric strength, stability, and mechanical hazards, energy connection and external versatile wire, grounding measures 12 projects have been tested. Monitoring results show that the good quality heater is not optimistic.
Unqualified project’s major problems and reasons:
1. Signs and guidelines failed. 15 samples failed the project logo and description, primarily heater failure or warnings on the indicators describing incomplete. Logo incomplete, that is, the traits of the solution itself can not be unmistakably told to customers, simply lead to misuse of items and professional service due to the fact they do not harm.
2. Input power and current failure. The spot checks, ten samples of input energy and present non-compliance. This project is fundamentally substandard products are much less than standard power range, energy is not enough as the heater will influence the results, take longer to attain the goal of heating, the customer will consume more electricity, the environmental protection energy saving is also adverse. The purpose is that an enterprise in order to lessen the production expense of high quality employed components for second lowest result.
3. Power connection and external versatile cord failed. The spot checks, 19 samples do not meet requirements. The principal problems is that the power cord and standard deviation for the nominal cross sectional region of the bigger and the lack of gear amongst the energy cord connector. Sectional area of the energy cord is not enough heat will result in massive quantity of work, affecting the life of the power cord, resulting in decreased wire insulation, easily lead to leakage accident. Connecting line among lack of cord will impact the security of electrical use.
4. Grounding measures failed. The spot checks in the grounding of 17 goods do not meet standards. Ground connection is to prevent the event of insulation failure, it can safeguard the solution effortless to touch metal parts will not leak, a solid and dependable ground connection essential. If ground is not strong, then the failure happens when the electrical insulation, can not leak through the ground wire leads, making it effortless case charged, causing electric shock. The reason is the manufacturers assembly method is not strictly enforce the guidelines, the normal factory test fails strictly to the project.
Sum up, the heater products mainly due to some random unqualified manufacturers of top quality consciousness, to decrease expenses, optional accessory top quality second lowest result.
For sampling final results, Industry and Commerce has notified the city’s shops and all sorts of household appliances appliance electrical products distribution company will be disqualified immediately from shelves and stop promoting to defend people’s use of security appliances for heating in winter
