11、CKETS (From EIA Standards Proposal No. 5109, formulated under the cognizance EIA CE-2.0 Committee on National Connector Standards, and previously published in EIA-364-18A.) 1 Introduction 1.1 Scope This standard establishes guidelines for visual and dimensional inspection of electrical connectors an

12、d sockets prior to, during, and after other test procedures. 1.2 Object The object of this test procedure is to detail standard methods for visual examination and dimensional inspection of test specimens in order to determine if the test specimens exhibit obvious defects that would affect test resul

13、ts or if a test has exposed obvious physical defects. It is not intended to substitute for full first article inspections, process capability studies and the requirements specified in the referencing document. 2 Test resources 2.1 Equipment 2.1.1 Visual examination shall be performed by the unaided

14、eye, corrected to normal vision. The use of magnification, polarized light, or other indications are not permitted, unless otherwise specified in the referencing document. 2.1.2 When specified, dimensional inspection shall be performed using suitable measuring tools and measuring equipment having an

15、 accuracy of at least one-third the tolerance for the variable to be measured. EIA/ECA-364-18B Page 2 3 Test specimen 3.1 Description A test specimen shall consist of a plug, a receptacle, or a mated plug and receptacle, or socket as specified in the referencing document. 3.2 Preparation The test sp

16、ecimen shall be examined as is. No additional preparation shall be performed, unless otherwise specified in the referencing document. 4 Test procedure 4.1 Visual examination 4.1.1 The initial examination is generally performed as a first step in a test program. It is intended to establish the genera

17、l condition of the lot of test specimens. Representative samples from the lots of specimens shall be randomly selected for the initial examination. If any part of the examination compromised the specimen, it shall not be used in subsequent tests. 4.1.2 Visual inspection such as workmanship, marking,

18、 finish, etc. shall be as specified in the referencing document. 4.2 Dimensional inspection When specified dimensional inspection shall be performed. Representative samples from the lots of specimens shall be randomly selected for the dimensional inspection. When required, a drawing shall be include

19、d in the referencing document and the dimensions to be inspected shall be indicated. 5 Details to be specified The following details shall be specified in the referencing document: 5.1 Number of specimens to be tested 5.2 Applicable standards and drawings 5.3 Special inspection conditions 5.4 Specif

20、ic visual workmanship, finish and marking requirements that need to be inspected EIA/ECA-364-18B Page 3 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 if appli
