MIL-PRF-49462C

3.23 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or

environmentally preferable materials should be used to the maximum extent possible provided that the

material meets or exceeds the operational and maintenance requirements, and promotes economically

advantages life cycles costs.

3.24 Workmanship. Resistors shall be processed in such a manner as to be uniform in quality and

shall be free from any defects that will affect life, serviceability, or appearance.

4. VERIFICATION

4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:

a. Qualification inspection (see 4.4).

b. Conformance inspection (see 4.6).

c. Periodic inspection (see 4.7).

4.2 Test equipment and inspection facilities. The supplier shall establish and maintain a calibration

system in accordance with NCSL Z540-1, ISO 10012-1, or equivalent system as approved by the

qualifying activity.

4.3 Inspection conditions and precautions.

4.3.1 Conditions. Unless otherwise specified herein, all inspections shall be performed in accordance

with the test conditions specified in the "GENERAL REQUIREMENT" of MIL-STD-202.

4.3.2 Precautions. Adequate precautions shall be taken during tests to prevent condensation of

moisture on resistors, except during the moisture resistance tests, and thermal shock tests. Precaution

shall also be taken to prevent damage by heat when soldering resistor leads to terminals.

4.4 Qualification inspection. Qualification inspection shall be performed at a laboratory acceptable to

the Government (see 6.3) on sample units produced with equipment and procedures normally used in

production.

4.4.1 Sample. The number of sample units comprising a sample of resistors to be submitted for

qualification inspection shall be as specified in the appendix A to this specification. The sample size shall

be taken at random from a production run and shall be produced with equipment and procedures

normally used in production. The sample unit shall have been subjected to and passed the requirements

of group A inspection (see 4.6.2). Qualification shall not be granted if group A inspection requirements

are not met.
