Xiangjie: UL, and IEC standards for small household electrical appliances in general differences
At present, production
Kitchen small appliances
Chia Tai exported to Europe and the United States, exports need to meet IEC, UL and other standards to overseas markets. Small kitchen appliances but the UL and IEC standards have not been coordinated, the work needs to be done to coordinate some complex differences between the standards. Meanwhile, UL standards are continuously updated to minimize the barriers between the future coordination of standards.
UL and IEC standards for comparison
IEC standards for small appliances mainly composed of two parts: IEC60335-1 standards for household and similar purposes
Electrical
Products
Security
General requirements put forward, and IEC60335-1 standard supporting the use of still IEC60335-2 Standard. IEC60335-2 Standard is the standard IEC60335-1 supplement were developed for all types of home appliances. Kitchen small appliances Total 4 IEC60335-2 family of standards, that is, IEC60335-2-9, IEC60335-2-13, IEC60335-2-14 and IEC60335-2-15. IEC60335-2-9 that "grill, roast
Bread
Machines and similar portable cooking equipment, specific requirements, "also applies to waffle machine, bread maker, oven,
Grills
, Baking trays and other similar small household electrical appliances; IEC60335-2-13 that is "hot frying pan, frying pans and similar product-specific requirements"; IEC60335-2-15 that "the specific requirements of the liquid heating products" for
Coffee
Pot,
Electric kettle
, Cooking pots, yogurt machine, egg machines and other similar small appliances; IEC60335-2-14 that "kitchen

The special requirements of goods, "applied to food

, Sharpening device, centrifugal
Juicer
And other small household electrical appliances.
In the U.S. market, the four types of products were applicable product standards: UL1026 "home electricity
Cooker
And
Food
Processing product standards "), UL1083" home electric skillet and frying pan-type product standards ", UL1082" home electric coffee maker and brewing products standards "and UL982" Standard for household electric food processor. "
Technical differences
(1) leakage current
Test
Measuring leakage current of devices in UL and IEC standards as described in seemingly different. But in fact, the measurement operation the difference was not large, but
Measuring instruments
Requirements vary.
Leakage current measurement instrument type UL1026, UL1082, UL1083 and UL982 standards are clearly defined. General market supply leakage current
Tester
For "perception" leakage current, usually meet the basic requirements of UL standards. However, these standards did not consider at this stage and non-sinusoidal high frequency leakage current. When the need to consider high-frequency and non-sinusoidal leakage current, the measuring instrument will be necessary to meet the UL101 standard "equipment leakage current standard" requirements.
The past, the leakage current value is the milliamp (mA) units. Now, in keeping with the latest version of "American Electric leakage current national standards-ANS
IC
101-1992 "requirement, expressed as a unit with MIU. MIU measuring instrument can be designated to read out the figures. Numerically, MIU only low-frequency consistent with mA. High frequency, the flow through the instrument of mA values are much larger than the display value of MIU. Therefore, the measurement should not use MIU mA leakage current is measured in units.
IEC60335 standard is IEC60990 standard creepage requirements based on the provisions, and its leakage test should be on any of its up to 1MHz frequency of the peak current to respond. UL product standards in
Test Equipment
And IEC standards are inconsistent.
(2) Dielectric strength test
For the nominal voltage 120V products, in addition to electric knife outside, UL standard insulation withstand voltage test of the test voltage is usually 1000V, time for 1 minute.
