ANSI SCTE 34-2016 pdf download.Test Method for Cored Depth Verification
1. Scope
The purpose of this test method is to determine the cored depth of Trunk, Feeder and Distribution Coaxial cable. The core depth is the internal measured distance between the dielectric foam and the square-cut end of the outer sheath. This test method will define the suggested method for core depth measurement.
2. Compliance Notation
This word or the adjective“required’ means that the item is an absolute requirement of this document. This phrase means that the item is an absolute prohibition of this document. This word means the value specified shall never be used. This word or the adjective“recommended’ means that there may exist valid reasons in particular circumstances to ignore this item, but the full implications should be understood and the case carefully weighted before choosing a different course. This phrase means that there may exist valid reasons in particular circumstances when the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label. This word or the adjective“optional? means that this item is truly optional. One vendor may choose to include the item because a . particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item. Use is permissible for legacy purposes only. Deprecated features may be removed from future versions of this document. Implementations should avoid use of deprecated features.
3. Equipment
3.1. Dial caliper
A Dial Caliper calibrated to read in at least 0.001 inch or 0.03 mm increments, a Mitutoyo 505-626 or equivalent.
3.2. Coring Tool
A Coring Tool for the coaxial cable to be tested.
4. Test Samples
Two-foot sample of the cable to be tested. Both ends should be square-cut and free of burrs or other impediments. If jacketed, and a jacket stripping/coring tool combination is not used, the jacket should be removed a sufficient distance as recommended by the manufacture to not impede the coring tool’s progress.
5. Test Measurement
1. Use the coring tool recommended by the tool manufacturer that corresponds to the cable to be tested. Verify the tool so that it matches the cable sample by the cable size and corresponding part numbers along with the tool part number and manufacturer’s recommendations.
2. Core the cable by following the coring tool manufacturer’s specific directions found on their instruction sheets.
3. Ensure the dial caliper is calibrated, and reads zero in the closed position. Extend the caliper out until it is just longer than the expected core depth as seen in Figure 1. Insert the dial caliper measuring blade inside the cored cable until the blade gently contacts the dielectric and lightly push down until the calipers butt contacts the cable outer sheath. Record this value as core depth. Record three measurements 120 degrees apart and average. The average core depth must meet the connector manufacturer’s specification for core depth.ANSI SCTE 34-2016 pdf download
