133 Introduction

134 When certifying or making declaration of conformity to the Low Voltage Directive 2014/35/EU in order to

135 CE mark the device it is important to state that the CE marking is only valid for the filter parts of the

136 product. The plug parts and socket-outlets parts are not covered by the Low Voltage Directive and are

137 therefore expected to comply with the relevant national standards.

138 1 Scope

139 This document applies to the filter part of portable devices for household and similar uses (hereafter

140 referred to as portable decoupling filters) consisting of the filter part, a plug or an appliance inlet or a

141 provision for connection by terminals or with a non-rewirable cord and a socket-outlet or an appliance

142 outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for

143 nominal voltages not exceeding 250 V a.c.
144 The filtering functions are described in EN 50065-4-1.
145 This document does not cover phase couplers.

146 Portable decoupling filters are not used as part of the fixed installation, where EN 50065-4-2 applies.

147 Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter

148 part are expected to comply with the relevant national standard(s).

149 Appliance inlets and appliance outlets connected to the filter part are expected to comply with the relevant

150 parts of the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not

151 covered by this document.

152 This document can be used for portable mains communication devices when no other product standard

153 exists.

154 This document can be used for other portable mains filters other than those described in EN 50065-4-1

155 when no other product standard exists.
156 Filters including batteries are not covered by this document.
