9 / 19 page MIL-PRF-19500/116L 9 4. VERIFICATION 4.1 Classification of inspections. The inspection requirements specified herein are classified as follows: a. Qualification inspection (see 4.2). b. Screening (see 4.3). c. Conformance inspection (see 4.4). 4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500 and as specified herein. 4.2.1 Group E inspection. Group E inspection shall be in accordance with MIL-PRF-19500 and table II herein. 4.3 Screening (JAN, JANTX, and JANTXV levels only). Screening shall be in accordance with table IV of MIL-PRF-19500 and as specified herein. The following measurements shall be made in accordance with table I herein. Devices that exceed the limits of table I herein shall not be acceptable. Screen (see table IV Measurement of MIL-PRF-19500) JAN level JANTX and JANTXV levels 3a Temperature cycling in accordance with MIL-PRF-19500 TX level.
