Wrap Test Specimens
N/A In the selection of MIL-W-5086/2 wire specimens for the wrap test, each sample length from which a specimen is to be taken shall first be subjected to the dye inspection described under the wrap test procedure of MIL-W-5086, in order to detect glass fiber protrusions, if present, which permit dye penetration into the underlying braid. Specimens for the wrap test shall be cut only from those portions of each sample length which are free of such glass fiber protrusions. |
- 1 Voltage rating at sea level
- 2 Also for bend tests after immersion.
- 3 The maximum shrinkage permitted for PVC insulation is .060 inch. Sizes 8 through 0000 gauge wire is permitted to have the braided polyamide outer jacket and glass braid insulation layers shrink .125 inch maximum.
