In the event of a conflict between the text
43、 of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS 3.1 Acceptable Quality Level (AOL). When a continuous series of l
44、ots is considered, the AQL is the quality level which, for the purposes of sampling inspection, is the limit of a satisfactory process average (see 4.3.1). 3.2 Classification of defects. A classification of defects is the enumeration of possible defects of the unit of product classified according to
45、 their seriousness. 3.3 Critical defect. A critical defect is a defect which reduce materially the usability of the product for its intended purposes and resulted in failure of the system or equipment or both system and equipment. . 4 Provided by IHSNot for ResaleNo reproduction or networking permit

A defect is any nonconformance of the unit of product with specified requirements. 3.5 Imperfect thread. The runout thread on externally threaded parts is incomplete and less than one pitch in length,
47、causing abrupt change in cross sectional area. 3.6 Inspection. Inspection is the process of measuring, examining, testing, or otherwise comparing the unit of product with the requirements. 3.7 Leg length. The length of the port, male or female, measured from the end of the part to the center of the
48、body vertically or horizontally. 3.8 Maior defect. A major defect is a defect, other than critical, that will have effect on usability that is likely to result in failure if used, or it will reduce materially the usability of the unit of product for its intended purpose. 3.9 Minor defect. A minor de
49、fect is a defect other than major, essentially no effect on usability, that is not likely to reduce materially the usability of the unit of product for its intended purpose, or having little bearing on the effective use or operation of the unit. 3.10 Not measurement sensitive document.
