Conclusion
All subject test specimens, connector components,
materials, accessories and contacts covered by this
report satisfied and/or exceeded the specified
requirement.
The successful completion of the qualification pro-
gram as reported herein, demonstrates the capa-
bilities of the subject ITT Cannon DPK series
connectors to comply with stringent verification
qualification requirements in accordance with
MIL-C-83733. On the basis of testing, the DPK
connector series was granted full OPl status to
MIL-C-83733.
