IEC 60335-1:2010 deals with the safety of electrical appliances for household and similar purposes.
Table1 shows the comparison of requirement between IEC60335-1 and IEC60950-1 in terms of safety.
|#||Safety standard||IEC60950-1||IEC60335-1 200V||IEC60335-1 100V|
|Over voltage category||Ⅱ||Ⅱ||Ⅱ|
|Input - Output||3,000||2.4･U+2400||2,000|
|Input - FG||1,500||1.2･U+950||1,000|
|Output - FG||(500)||-||-|
|Portable class I appliances||-||0.75mA||0.75mA|
|Stationary class I motor-operated appliances||-||3.5mA||3.5mA|
|5||Maximum temperature (Wire)||Type A||Less than 90℃||-||-|
|Type E||Less than 105℃||-||-|
|Type B||Less than 110℃||-||-|
|6||Temperature increasing (Wire)||Type A||-||Less than 65deg||Less than 65deg|
|Type E||-||Less than 80deg||Less than 80deg|
|Type B||-||Less than 85deg||Less than 85deg|
*1:(U) Maximum working voltage
*2:(Basic isolation/Reinforced isolation)
*3:Listed voltage means working voltage.
*4:Listed voltage means working voltage in IEC60950-1, and rated input voltage in IEC60335.
Required creepage in IEC60335-1 is more strict than IEC60950-1 in some part.
In IEC60950-1, type of wire is categorized by the absolute maximum temperature. In IEC60335-1, type of wire is categorized by the temperature increasing against temperature at 25ºC ambient temperature.
2pcs of Y1 grade grounding capacitors shall be used in series to comply with IEC60335-1.
The creepage and temperature of wire are different depending on the product.
