For class 1 terminals a

37、nd conductor splices, it shall be possible to perform the reshaping operation by means of a crimping tool or crimping dies conforming to the applicable AS or MS specification sheet. For class 2 terminals and conductor splices, it shall be possible to perform this reshaping operation by means of tool

38、ing detailed on the manufacturers control drawings. Terminals and conductor splices shall exhibit no evidence of fracturing or spalling as a result of the reshaping operation. Wire insertion shall be facilitated by bell mouth or chamfer of wire barrel. There shall be no protruding sharp edges of the
