The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN

14、 50065-4-7 on 2004-12-01. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2006-02-01 latest date by which the national standards conflicting with the EN have to be withdrawn (

15、dow) 2007-12-01 This safety standard EN 50065-4-7 has no frequency dependent content. It was originally conceived as a safety document within the EN 50065 set of standards, which have a frequency of 3 kHz to 148,5 kHz. When the scope of SC205A was extended to 30 MHz, SC 205A agreed that the scope of

16、 the published safety standard, EN 50065-4-2, Low voltage decoupling filters - Safety requirements, should be amended to include the band 1,6 MHz to 30 MHz in order to cover the additional set of standards for 1,6 MHz to 30 MHz. This required no technical changes to the body of the document. In addi

17、tion, it was agreed that Part 4-7, Portable low voltage decoupling filters - Safety requirements, should also cover both frequency ranges. For this reason the title of this part of EN 50065 covers the extended frequency ranges 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz. When certifying or making decla

18、ration of conformity to the Low Voltage Directive 73/23/EEC in order to CE mark the device it is important to state that the CE marking is only valid for the filter parts of the product. The plug parts and socket-outlets parts are not covered by the Low Voltage Directive and shall therefore comply w

19、ith the relevant national standards.

32、ug or an appliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple) 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. to neutral o

33、perating in the frequency range 3 kHz to 148,5 kHz and from 1,6 MHz to 30 MHz. The filtering functions are described in EN 50065-4-1. This standard does not cover phase couplers. Portable decoupling filters shall not be used as part of the fixed installation, where EN 50065-4-2 applies. Plugs and so

34、cket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter part shall comply with the relevant national standard(s). Appliance inlets and appliance outlets connected to the filter part shall comply with the relevant parts of the EN 60320 series. Appliance inlet

35、s and appliance outlets integrated with the filter parts are not covered by this standard. This standard can be used for portable mains communication devices when no other product standard exists. This standard can be used for other portable mains filters other than those described in EN 50065-4-1 w

36、hen no other product standard exists. Filters including batteries are not covered by this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
