After enquiries and vot
12、es 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 ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, e
13、ither by publication of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by April 2007. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/o
14、r CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,

EN 2349-307:20064 1 Scope This standard specifies a method for tes
16、ting the contact voltage drop 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 edition cited applies. For undated references, the late
17、st 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 Test procedures 3.1 The contact voltage drop shall be measured both on normally-open and normally-clos
18、ed contacts. 3.2 For qualification tests of relays or contactors with plug-socket holders, the voltage drop of the plug-socket holder shall be taken into account in accordance with the product standard. 3.3 For testing in the energized state the rated voltage shall be applied to the coil. 3.4 Contac
19、t loading is the rated resistive load for qualification testing. 3.5 The open contact voltage is 6 V d.c. for relays or contactors with ratings of up to 25 A and 28 V d.c. for relays or contactors with ratings over 25 A (d.c. or a.c voltage is acceptable). 3.6 For batch testing the contact load may
20、be below the rated current, but the voltage drop measured shall be projected for the maximum permissible value at rated current. 3.7 The contacts shall not be switched under load, unless otherwise specified in the product standard. 3.8 The measurement shall be taken between 3 s and 10 s after connec
21、tion of the test current. 3.9 The number of measurements shall be as follows: for batch acceptance and acceptance inspection: 1; for qualification testing: 10. 4 Test criteria The contact voltage drop shall not exceed the value specified in the product standard. 1) In preparation at the date of publ
