permanently marked on the adapter, nozzle, pressure cap, and dust cap in accordance with
MIL-STD-130.
3.9 Workmanship. Fittings shall be free from burrs and tool marks. All sealing surfaces shall be
smooth.
4. VERIFICATION
4.1 Classification of inspection. The inspection requirements specified herein are classified as
follows:
a. Qualification inspection (see 4.3).
b. Conformance inspection (see 4.4).
4.2 Inspection conditions. Unless otherwise specified, all inspections shall be performed in
accordance with the test conditions specified in 4.7.1, 4.7.2, 4.7.3, 4.7.4, 4.7.5, 4.7.6, 4.7.7, 4.7.8, 4.7.9,
