After enquiries and votes carried out in accordance with
12、the rules of this Association, this Standard has 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 identic
13、al text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by April 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard:

15、064 1 Scope This standard specifies a method for testing the rupture characteristics of relays and contactors. It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the
16、edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 2349-100, Aerospace series Requirements and test procedures for relays and contactors Part 100: General requirements 1)3 Mounting method The relay or contactor shall be
17、 wired in accordance with EN 2349-100 and the rated contact load. The test sample shall be mounted in still air. 4 Test procedures 4.1 Each operating and resting contact shall be able to connect, conduct and disconnect the loads specified in the product standards. 4.2 During the test, the housing of
18、 the relay or contactor shall be connected to the d.c. earth or the neutral lead of the electrical installation by a fuse with a rating of 5 % of the rated resistive contact current, but not greater than 3 A. 4.3 One sample shall be tested for each load. Operating and normally closed contacts shall
19、be tested separately. For tests with multi-phase a.c. current, the load shall be applied to adjacent contacts. 4.4 The coil of the relay or contactor shall be energized at the rated voltage during the test. 4.5 The contacts shall be monitored during connection, conduction and disconnection. 4.6 A fu
20、nctional defect shall constitute a failure. A voltage drop over 10 % of the open contact voltage shall constitute a failure. Blowing of the fuse shall constitute a failure. 4.7 Test cycle: connection time: (0,2 0,05) s; disconnection time: (30 1) s. Number of test cycles: see product standard. 1) In
21、 preparation at the date of publication of this standard. EN 2349-310:20065 4.8 The temperature increase shall be measured for: plug-in relays, on the case; screw-type connections: on the connector bolt. 5 Test criteria No electrical or mechanical failure; no sticking or seizing of contacts; no blow
22、n fuse; no temperature increase above 75 C.
