use of special tools within the specified temperature range.
Workmanship. Connectors shall be uniform in quality and shall be free from burrs,
scratches, cracks, voids, chips, blisters, pin holes, sharp edges, and other defects that
will adversely affect life or serviceability.
Interchangeability. The connector shall be capable of mating with any appropriately
constituted male connector of the same population without degradation in performance.
