EIA-364F Page 4 2 Requirements 2.1 Qualification Qualification sequences and se

12、verity levels shall be invoked by the referencing document. The referencing document shall reference the applicable class and the specific test sequences to be used for product qualification. 2.1.1 Qualification of a connect/socket series may be established by similarity through testing parts repres

13、enting the maximum size or as defined by the qualifying agency. A series includes connectors/sockets and contacts of identical deign, spacing and configuration. 2.1.1.1 Similarity shall be granted for all sizes up to that level to which testing has been performed. Specimens for all sizes for which s

14、imilarity is desired shall be submitted at the time of qualification. 2.1.1.2 Qualified contacts which have the same physical dimensional configuration, base material, plating type and thickness, material thickness in the engagement area except that the termination area has been changed (e.g. crimp,

15、 solder, IDC, etc.) shall be qualified with testing pertinent to the termination technique involved. 2.1.2 Following a connector/socket qualification, the manufacturer shall make no design changes, substitutions, material changes or process changes that affect from, or function, without full or part

16、ial requalification. 2.1 2 1 Requalification may consist of only those tests pertinent to the specific attributes that may be affected by said changes. 2.1.3 To successfully qualify or requalify a connector/socket series, test samples shall meet all the requirements as specified within the specified

17、 test groups. Deviation from the specified requirements may be granted only by the qualifying agency. 2.1.4 To successfully qualify, each specimen shall pass all the test requirements as specified for each test in the sequences indicated. No defects shall be allowed. 3 Qualification procedure 3.1 Te

18、st sequence 3.1.1 The test specimens shall be subjected to the test sequence as shown in figure 1. The test sequence establishes the order of exposure to the environmental conditions, and the subsequent test parameters measured to determine adequate performance for each connector/socket class. 3.1.2

19、 Specific tests may be added or deleted from the recommended sequence, supplemental and/or termination test s contingent on the specific application. EIA-364F Page 5 3.2 Specimen size 3.2.1 The sample size shall be as specified in the referencing document. If not specified, each test group shall con

20、sist of the quantity of the test specimens shown in figure 1. Each specimen consisting of both mated halves with a full complement of contacts and shall include applicable hardware when appropriate. 3.2.2 The referencing document shall specify the number of data points to be monitored for each attri

21、bute. If not specified, 25% of the contact positions/specimen shall be measured but not fewer than 25. If there are fewer than 25 contact positions then all contact positions shall be measured. Additional specimens shall be added in order to obtain 25 data points for those situations when the number

22、 of positions are less than 25. When applicable, the positions measured shall be identified by a specimen identification and position number. All positions to be monitored shall be randomly chosen or as specified. 3.3 Standard atmospheric conditions 3.3.1 Unless otherwise specified, all measurements

23、 shall be made within the following ambient conditions: Temperature: 15 to 35 C, Atmospheric pressure: 650 millimeters of mercury to 800 millimeters of mercury, Relative humidity 20% to 80%. 3.3.2 Special tests may require tighter control of conditions when specified in the test procedure. 3.4 Test

24、specimen The test specimens shall be representative of the manufacturers normal production and shall be selected at random. Each test specimen or part thereof shall be individually identified, such that the marking will not be destroyed throughout the test. 3.5 Test specimen disposition Following co

25、mpletion of the test program, test specimens should be packaged and retained by the testing facility or test sponsor for not less than one year unless otherwise specified in the referencing document. Unit identification and all test report identification shall be included in each package. EIA-364F P

26、age 6 3.6 Test data The results of each test shall be recorded as data.
