Some common factors to check for home appliances quality control：
1.Sign, clear design, there is full name of the manufacturer, product name, type, size, trademarks, date of manufacture or production batch number, electrical schematics
2. Plastic surface is smooth, uniform color, there should be no obvious scars, seams match, shapely, silk screen design, text clarity, power lines fixed retainer in the correct position, the coating should be smooth plating fine, uniform color, should not be there are spots, pinholes, bubbles and paint stripping, surface coating must be smooth and bright.
3. Insulation Resistance Test :When the International Electrotechnical Commission (IEC) standard insulation resistance measurement between live parts and the housing, basic insulation condition of the insulation resistance value of not less than 2MΩ; reinforced insulation condition of the insulation resistance value of not less than 7MΩ;Ⅱclass electrical live parts only between the metal parts and the housing and the only basic insulation and metal parts separated from live parts, insulation resistance value of not less than 2MΩⅢclass basic electrical insulation and isolation of live parts, insulation resistance value of not less than 5MΩ.
4. Leakage Current Test : Household appliances leakage current is the electrical voltage in the role of the test to measure the leakage current for all kinds of household appliances, national standards are also specified leakage current should not exceed the upper limit of the product before it leaves the factory to be tested. When voltage is applied to the test site for household appliances of rated voltage 1.06 times (or 1.1 times), the applied voltage is measured within 5 sec, the test voltage is applied between live parts and appliances with live parts by basic insulation only isolated case and between live parts and live parts by reinforced insulation and isolation housing.
5. Insulation electric strength test:General requirements for provisions, After heating appliances as temperature and humidity tests have to be electric strength test, Electric appliance test only backward heat Line electric strength test. Long-term use of household appliances in the process, not only to withstand the rated voltage, but also to work during the short period of time Higher than the rated working voltage over-voltage action, when over-voltage reaches a certain value, it will cause insulation breakdown, household appliances can not be properly Work, the user may endanger the safety of electric shock. Electric strength test, commonly known as pressure test, which measures the electrical insulation overvoltage Resistant to breakdown under the influence of ability, which is a kind of assessment to ensure that the product is safe and reliable means. Two types of electric strength test: a DC voltage test, the other is the AC power frequency voltage withstand test. Household products generally cross flow frequency voltage withstand test. Electric strength test test site and test voltage in each product standards have made specific instructions and regulations.
