21、hall apply. The thickness of sheath shall comply with the specified values given in Part 10, Table I, column 6. The requirement of sub-clause 5.5.3 of Part 1 shall apply. Slight deformation of the cord, created by the coil forming process, is acceptable provided that the thicknesses of the insulatio
22、n and sheath meet the requirements. Markinq The original marking, if any, on the pre-coiled cord may be affected by the coiling process, but this is acceptable provided that traceability is not impaired. The inclusion of the Common Marking (4HARo) as part of any original marking is not to be taken a
