After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This European Standard shall be given
15、 the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2006, and conflicting national standards shall be withdrawn at the latest by April 2006. Attention is drawn to the possibility that some of the elements of this document may be th

EN 2591-212:2005 4 1 Scope This standa
18、rd specifies methods for measuring the surface transfer impedance and shielding effectiveness up to 1 GHz of a connector, or a connector fitted with an accessory and terminated with a cable. The purpose of the test is to ensure that the complete assembly shall have a continuous 360 shielding capabil
19、ity throughout its length. This test is based on EN 60512-23-3. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced documen
20、t (including any amendments) applies.

21、prepared in accordance with EN 60512-23-3. 4 Apparatus The apparatus shall be in accordance with EN 60512-23-3. 5 Procedure The test shall be carried out in accordance with EN 60512-23-3. 6 Requirements The surface transfer impedance, expressed in m , or converted to shielding effectiveness expresse
22、d in dB, shall not exceed the values specified in the product standard. 7 Details to be specified The following details shall be specified: Surface transfer impedance, outside diameter of cable screen and construction of cable, if fitted; The frequency range over which the measurements were carried
23、out; Any limitations on the effective frequency range of the test due to resonances. blankBS EN 2591-212:2005 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for preparing British Standards.
