3.5.5 Contact retention. Contacts for classes G, D, M, and N connectors shall be retained in their inserts by a

9-pound (minimum) force. The axial displacement of contacts shall not exceed .012 inch (0.30 mm) while under load

(see 4.5.7).

3.5.6 Dielectric withstanding voltage. Unmated connectors shall show no evidence of breakdown or flashover when

subjected to the test voltages and altitudes specified in tables III and IV. Corona shall not be considered as

breakdown. Testing shall be as specified in 4.5.8.
