This test is typically used as a process control test to ensure that the measured diameter of a manufactured wire/cable is within the range provided in the wire/cable specification. The wire/cable is measured in multiple locations and the average diameter is reported. For non-uniform cables, such as twisted pairs, measurements are made both for the minimum and maximum diameter.
This test is often included as part of post-environmental exposure testing (e.g. fluid immersion testing) to determine if there has been any insulation expansion or shrinkage.
Our Process
1
Perform visual examination of the specimens. Record any observed defects.
2
Use calibrated calipers to measure the specimen at three or more locations. At each location, two measurements should be made with a 90Degree rotation between the two measurements.
3
Record the minimum and maximum diameters recorded the average diameter.
