Inspection requirements spec
36、ified herein are classified as follows: a. First article inspections (see 4.4). b . Quality conformance inspections (see 4.5). 4.2 Tesi. - equipment. All test equipment utilized by the contractor or performance ofthe inspections specified herein shall be calibrated and maintained in accordance with
37、MIL-STD-45662. 4.2. i Standard test equipment. The contractor shall provide and main tain inspection and test equipment of sufficient quality and quantity to permit the performance of the required tests and measurements, under the conditions and to the accuracies specified herein. Unless otherwise s
38、pecified herein, the magnitude of any error introduced by the test equipment shall not exceed 10 percent of the allowable tolerance of the requirement being measured. All test equipment shall be calibrated and maintained as specified in 4.2. 4.2.2 Special test equipment and circuits. When special te
39、st equip- ment and circuits, other than as specified herein, are devised or commercially -available equipment is employed, all test equipment, circuits, and methods shall meet the requirements of 4.2.1 and are subject to approval by the procuring activity, 4.2.3 Gages.
