11、 EIA CE-2.0 Committee on National Connector Standards, and previously published in EIA-364-15B.) 1 Introduction 1.1 Scope This standard establishes a test method to determine the exposed contact (pin or socket) strength for contact sizes 20 and smaller when subjected to a defined bending stress (or

12、moment). 2 Test resources 2.1 Test equipment Test equipment shall consist of a displacement meter and a suitable means of positively securing the exposed contact. 2.1.1 Displacement meter A displacement meter (i.e. dial indicator) having an accuracy of 5% shall be used to measure permanent set. 2.1.

13、2 Mounting fixture A fixture that positively secures the exposed contact, in the area indicated in figure 1, shall be used. 3 Test specimen 3.1 Description A test specimen shall consist of an exposed contact, unless than otherwise specified in the referencing document. 3.2 Preparation The test speci

14、men shall be secured in a suitable mounting fixture as indicated in figure 1, unless otherwise specified in the referencing document. EIA-364-15C Page 2 4 Test procedure 4.1 Test load The test load shall be applied as indicated in figure 1, with the rate of travel of the loading mechanism not exceed

15、ing 25.4 millimeters / minute (1.0 inch / minute). The load shall be maintained for 60 seconds +15 seconds, -0 seconds. 4.2 Permanent set The permanent set shall be the difference between the initial position of the contact before the load is applied, and the final position of the contact after pres

16、cribed load has been removed. The degree of permanent set shall not exceed 0.13 millimeters (0.005 inch) at the 0.8 L load point unless otherwise specified in the referencing document. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Number of speci

17、mens to be tested 5.2 Test specimen description 5.3 Special preparations or conditioning, if required 5.4 Minimum moment required per individual contact size, see figure 1 5.5 Duration of test load application, if other than specified in 4.1 5.6 Maximum permissible permanent set, if other than speci

18、fied in 4.2 6 Test documentation Documentation shall contain the details specified in clause 5, with any exceptions, and the following: 6.1 Title of test 6.2 Specimen description, including fixturing 6.3 Test equipment used, and date of last and next calibration 6.4 Test and procedure 6.5 Values and
