Licensed Copy: Wang Bin, na, Mon May 08 02:43:05 BST 2006, Uncontrolled Copy, (c) BSIEN 2591-212:2005 4 1 Scope This standard 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 termina
20、ted with a cable. The purpose of the test is to ensure that the complete assembly shall have a continuous 360 shielding capability 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 docum
21、ent. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

22、3c : Shielding effectiveness of connectors and accessories (IEC 60512-23-3:2000) 3 Preparation of specimens Specimens shall be 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
23、EN 60512-23-3. 6 Requirements The surface transfer impedance, expressed in m , or converted to shielding effectiveness expressed 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, outsi
24、de diameter of cable screen and construction of cable, if fitted; The frequency range over which the measurements were carried out; Any limitations on the effective frequency range of the test due to resonances.
