4. VERIFICATION

4.1 Sampling and inspection. Sampling and inspection shall be in accordance with MIL-PRF-23648.

4.2 Terminal strength.

4.2.1 Direct load. Direct load shall be applied gradually until the load reaches 1.0 pound.

4.3 Solderability. The solderability test is applicable to this specification except the steam aging

requirement shall be 60 minutes +5 minutes, -0 minutes.

4.4 Resistance to soldering heat. The resistance to soldering heat test is applicable to this

specification.

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the

contract or order (see 6.2). When actual packaging of material is to be performed by DoD personnel,
