4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are
classified as follows:
a. Qualification inspection (see 4.2).
b. Conformance inspection (see 4.3).
4.2 Qualification inspection. Qualification inspection shall consist of the examinations
and tests specified in the applicable specification sheet. The specification sheets also list the
order in which the tests shall be conducted. If a test is not listed in the test table(s) of the
specification sheet, then it is not required for the connector. The samples shall be representative
of the items intended to be supplied under this specification. The samples shall not be produced
with the use of any equipment or procedure not normally used in production of the battery.
Three connectors shall be furnished for inspection. In addition, two samples each of all metal
parts that have been plated shall also be furnished for inspection. The plated parts shall have
been treated and processed as they would be for fabrication of finished connectors. All samples
shall be marked with identifying information in accordance with 3.10.2. A qualification sample
that fails any of the examinations or tests specified herein shall be cause for the qualifying
activity to refuse to conduct additional testing until the defects revealed by the inspection have
been corrected.
4.3 Conformance inspection. Conformance inspection shall consist of the examinations
and tests specified in the applicable specification sheet. The specification sheets also list the
order in which the tests shall be conducted. If a test is not listed in the test table(s) of the
specification sheet, then it is not required for the connector. Connectors produced under this
specification shall successfully complete conformance inspection. Units shall be formed into
inspection lots (see 6.10.2 and 6.10.3). The sample size for conformance inspection shall be as
shown in table IV. Connectors produced under this specification shall be identical in every
respect to the qualification sample tested and found satisfactory, except for changes previously
approved by the Government. Any unapproved changes from the qualification sample shall
constitute cause for rejection.
4.4 Inspection conditions. Unless otherwise specified in the description of the test, all
inspections shall be performed in accordance with the following test conditions.
4.4.1 Temperature and storage conditions. Connectors, components, and materials that
will undergo testing shall be temperature-stabilized for not less than 2 hours before electrical
tests are initiated. During the entire period in the environmental chamber, elevate the connector
by not less than 0.75 inch from the floor of the chamber for full air circulation. Unless otherwise
specified in the description of the test, room temperature shall be 25° ± 5° C (77° ± 9° F), high
temperature shall be 71° ± 2° C (160° ± 3.6° F) and low temperature shall be -85° ± 1.1° C
