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.

*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.
