The contact area between the two wires shall be a minimum of three wraps (not twists) of each wire around the other.
Acceptable - Class 1,2,3
• Interlocking of two wire strands into a smooth joined section
for a minimum of three wraps of each conductor.
• No conductive strands piercing the insulation.
• Insulation covers splice and overlaps wire insulation a minimum
of one wire diameter (not shown).
Process Indicator - Class 2,3
• Wire bulges the insulation but does not pierce it.
Defect - Class 1,2,3
• There are sharp points or projections.
• Conductor strands pierce the insulation.
• Wire splice area is exposed.
• Insulation does not overlap wire splice area for a minimum of
one wire diameter.
• Less than three wraps of each conductor.
