scope:
This document applies to the filter part of portable devices for household and similar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and a socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c.
The filtering functions are described in EN 50065-4-1.
This document does not cover phase couplers.
Portable decoupling filters are not used as part of the fixed installation, where EN 50065-4-2 applies.
Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter part are expected to comply with the relevant national standard(s).
Appliance inlets and appliance outlets connected to the filter part are expected to comply with the relevant parts of the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not covered by this document.
This document can be used for portable mains communication devices when no other product standard exists.
This document can be used for other portable mains filters other than those described in EN 50065-4-1 when no other product standard exists.
Filters including batteries are not covered by this document.
