When production is resumed after one year of suspension; When the factory inspection result is significantly different from the last type inspection; The national quality supervision agency or the superior inspection agency requires the inspection of this item 6.2.3 Sampling method:
- Destructive type inspection: Randomly sample three sections from three rolls of cable, each section is 5m long Non-destructive type inspection: Randomly sample three rolls, and the length of each roll section is not less than 100m. Type inspection

Appendix A
(Appendix of the standard)
Sheath sliding force test
This test method is applicable to the test of filled water-blocking seismic cables. Sample selection
Cut four sections of 600mm long samples from qualified cable products. A3 Sample preparation
Remove 100mm of sheath from one end of the 600mm long sample without damaging the cable core. Measure another 100mm of sheath from the end where the sheath is stripped and keep it, and peel off all the other sheaths. Prepare a 3-5mm steel plate (or other metal material of appropriate strength) and drill a hole on it. The diameter of the hole allows the cable core to pass freely, but the expansion sheath stays around the hole on the plate. A4 Sample treatment
Put the sample in a 50℃12 environment for 1h before testing, and then test it immediately. Test method
Immediately fix the treated sample on the stretching machine and stretch it at a speed of 50mm/min until the sheath slides 100in. Record the maximum load obtained.1.1 The surface of the cable sheath has continuous markings of the manufacturer's name and model, and the markings are clear and easy to identify.
