Qualiy conformance inspection (see 4.4). 4.2 Classification of characteristics. The characteristics ver

30、ified by the tests and examination herein are classified as critical, major, or minor in accordance with DOD-STD-2 1 O 1. Tests and examinations that veri+, criticai charac6stics are identified by the symbol (C) and major characteristics by the symbol (M). The number following the classification sym

31、bol indicates the serial number of test or examhation. Tests and examinations which are not annotated with a classification code are classified minor. 4.3 First article inspection. First article inspection shall be performed after award of contract and prior to production by a facility designated in

32、 the contract (see 6.2). A first article sample acceptable for environmental and function testing shall be considered as a sample which has met the requirements of 3.2 through 3.4.2.3 and 3.7.
