A.3.3 Sample submission. Contact Qualifying Activity (Defense Supply Center, Columbus, Attn:
DSCC-VQP, P. O. Box 3990, Columbus, OH 43218-3990, vqp.chief@dla.mil) for submission instructions
for intermateability and interoperability test samples.
A.3.4 Sample disposition. Test samples submitted shall be retained by the Government as
standards for use during future intermateability and interoperability testing. For the purpose of
maintaining test standard integrity and security of vendors to certain types of product exposure, test
standards will not be loaned outside the Government test lab.
A.4 QUALIFICATION INSPECTIONS.
A.4.1 Intermateability. All combinations of fully populated connectors from all manufacturers shall
be mated and tested for insertion loss in accordance with 4.8.1. Results shall not exceed the
requirements of 3.10.1.
A.4.2 Interoperability. All interchangeable components (backshells, termini and other components
as applicable) shall be removed from both qualified and submitted connector plugs and receptacles. At
random, interchangeable components shall be inserted into and shall fully populate submitted connector
examples based on test variations for one certified device and one candidate device. As additional
devices are certified, the amount of test variations will increase in order to test the candidate device to
each certified device. If multiple qualified termini exist, all sources will be used at random during test. At
random, connector assemblies shall be mated and insertion loss shall be measured in accord with 4.8.1.
Results shall not exceed the requirements of 3.10.1.
