PPS 9.55, Issue 1 - Qualification of Crimp Tools
     Summary of Changes:

This is a new PPS raised to specify the procedure and requirements for qualification of crimp tools used for crimp termination of copper and/or aluminum wire at electrical terminal lugs, splices and/or contacts.

This PPS is based in part upon information specified separately in PPS 9.01, PPS 9.09, PPS 9.19, PPS 9.20, PPS 9.35 and PPS 9.36, however changes and additions have also been made, summarized as follows.

Added authorization for qualification of crimp tools according to BAPS 145-029 or BAPS 145-260.

Added new sub-section 3.1 and para. 3.1.1, to ensure correct usage of reference specifications.

Created new sub-sections 3.2, 3.3 and 3.4 to identify document references. o Added new para. 4.1.1, to prevent inappropriate material substitution.

Added requirements to use calibrated tensile testing machines and scale force indicators.

Added requirement that tensile testing must be performed at a BAERD GEN-018 approved facility.

Added clarification of the maximum acceptable interval between crimping tool qualifications.

Added clarification that for the purposes of this PPS there is no difference between initial qualification of crimp tools and re-qualification of crimp tools.

Clarified instructions regarding make-up of test samples and which test samples are required for tool qualification.

For test samples comprising of terminal lugs crimped to copper wire according to PPS 9.01 or splices crimped to copper wire according to PPS 9.09, the tensile strength requirements for tin and silver coated copper wire have been so identified, and tensile strength requirements for nickel coated copper wire have been added.

For test samples comprising of M39029 contacts crimped to copper wire according to PPS 9.19, PPS 9.20 and PPS 9.36, replaced minimum tensile strength requirements based upon contact wire barrel size with minimum tensile strength requirements based on wire size.

This revision notice lists brief summaries of technical changes introduced for each of the revised PPS's. Please note that these summaries are not detailed and are intended only to assist in alerting users to changes which may affect them; refer to the applicable PPS for authorized, detailed procedure and requirements.
