5.0 Testing
Test methods are based upon EIA Standard 364.
5.1 General
Visual (Appearance) — EIA-364-18
Purpose
The purpose of this test is to visually examine and dimensionally inspect the connector in order to determine whether
the connector conforms to the applicable specification and detail documents not covered by performance
requirements.
Test Method
The examination shall be made in accordance with EIA-364-18. The visual examination shall include inspection of
the following features as a minimum: workmanship, marking, materi als, finish, stand ards, design and constructi on.
The dimensional inspection shall be a check for compliance with the outline drawings of the detail specification.
5.2 Environmental
High Temperature Aging — EIA-364-17
Purpose
The purpose of this test is to determine the effects on the electrical and mechanical characteristics of the cable
assembly resulting from exposure of the cable assembly to an elevated ambient temperature fo r a specified length of
time.
Test Method
Mated connectors shall be tested in accordance with EIA-364 17.
