ANSI EIA 00364-007B-1998 pdf download Contact Axial Concentricity Test Procedure for Electrical Connectors
1 Introduction
1.1 Scope
This standard establishes a test method to determine the straightness of contacts by measuring a total indicator reading (TIR) value. Axial concentricity can be measured after crimping to determine axial deformation.
2 Test resources
2.1 Equipment
2.1.1 Ground precision chuck
2.1.2 Dial gauge indicator, 0.013 millimeter (0.0005 inch) increments with a 2.4 millimeter (0.09 inch) diameter tip, spring loaded.
2.1.3 Stand (for holding chuck and indicator in proper position).
2.1.4 An equivalent optical gauge may be substituted for the dial indicator.
2.2 Calibration
“Run out” of the chuck shall be less than 0.013 millimeter (0.0005 inch) when measured on a steel gauge pin (approximately 1.6 millimeter (0.06 inch) diameter) 13 millimeter (0.5 inch) away from the chuck face.
3 Test specimen
3.1 Description
A test specimen shall consist of a contact and conductor crimped together with the specified tool.
Contacts should be checked initially to determine conformance to the applicable drawings.
4 Test procedure
4.1 Chuck the contact in the area shown in figure 1.
4.2 Position the dial indicator to the measurement points shown in figure 1.
4.3 Turn the chuck through 360 degrees and record the difference between the maximum and minimum value on each measurement point; this is the TIR.
5 Details to be specified
The following detail shall be specified in the referencing document:
5.1 Wire type and size and crimping tool to be used
5.2 Maximum allowable deformation (TIR)
