scope:

This standard applies to fixed capacitors for radio interference suppression intended for appartus and machines to be connected to a supply with a nominal voltage not exceeding 500 V d.c. or a.c. (r.m.s.) between conductors or 250 V d.c. or a.c. (r.m.s.) between any one conductor and earth and a frequency not exceeding 100 Hz. Capacitors for specical environmental conditions (e.g. dripproof, splahs-proof etc.) have to fulfil additional requirements. Combinations of two or more capacitors within one enclosure are also included in the scope of this standard. This standard does not necessarily apply in its entirety to capacitor/resistor combinations, or to capacitors intended for use on motor vehicles, in aircraft of for marine applications. Individual recommendations for capacitors/resistor combinations, and capacitor for these other applications wil indicate non-applicable clauses and extra requirements.
