5. Safety Approval for Power Line Filter

1. Why Be Concerned With Safety Agency Requirements?

All components in the AC power system, including power line filters, must be safe from potential fire and shock hazard. The standards set by the various safety agencies, such as UL, CSA and VDE provide guidelines to assist the designer in specifying safe and reliable components. Components which carry the compliance symbols from these agencies have been designed and manufactured to comply with these standards.

2. International standard for EMI filter

1）IEC939-1:Complete filter units for radio interference suppression. Part 1: Generic specification 2）IEC939-2:Complete filter units for radio interference suppression.Part 2: Sectional specification. Selection of methods of test and general requirements 3）UL1283:Standard for Electromagnetic Interference Filters 4）CSA C22.2 No.8:Electromagnetic Interference (EMI) Filters 5）CISPR－17:Methods of measurement of the suppression characteristics of passive radio interference filters        and suppression components 6）UL1414:Standard for Capacitors and Suppressors for Radio and TelevisionType Appliances 7）IEC335－1:Standard for Safety of Household and Similar Electrical Appliances. Part 1:General Requirements 8）EN60939: Complete filter units for radio interference suppression 9）EN60384-14:Fixed capacitors for use in electronic equipment.
