After enquiries and votes carried out in accordance with the rules of this Association, this Standard has

12、received the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June

13、2008, and conflicting national standards shall be withdrawn at the latest by June 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights

EN 2591-226:20074 1 Scope This standard specifies a test method to determine no sustained Corona discharge on a mated pair of connectors. It

16、shall be use together with EN 2591-100. 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 document (including any amendme

No grease or similar compound shall be used in or on the test item. After the sample is purged of air, the 50 Hz voltage

21、shall be slowly increase until the detector operated at a sensitivity of five picocoulombs level or less. The latter Voltage value is being the Corona level of the connector under test.
