27、 number and diameter, heat treated together to the same specified condition and produced as one continuous run 3.2 inspection lot quantity of parts from a single production batch of the same part number which completely defines the part 3.3 Surface discontinuities 3.3.1 crack rupture in the material

28、 which may extend in any direction and which may be intercrystalline or transcrystallyne in character 3.3.2 seam longitudinal surface defect in the form of an unwelded open fold in the material 3.3.3 lap surface defect caused by folding over metal fins or sharp corners and then rolling or forging th

29、em into the surface 3.3.4 inclusion non-metallic particles originating from the material making process. They may exist as discrete particles or strings of particles extending longitudinally 3.4 test temperature ambient temperature, unless otherwise specified 3.5 simple random sampling the taking of

30、 n items from a population of N items in such a way that all possible combinations of n items have the same probability of being chosen ISO 3534, see definition 3.6 critical defect defect that according to judgment and experience is likely to result in hazardous or unsafe conditions for individuals

31、using, maintaining, or depending upon the considered product or that is likely to prevent performance of the function of a major end item ISO 3534, see definition 3.7 major defect defect other than critical, that is likely to result in a failure or to reduce materially the usability of the considere

32、d product for its intended purpose ISO 3534, see definition Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 25/03/2010 06:58, Uncontrolled Copy, (c) BSIBS EN 3388:2009EN 3388:2009 (E) 6 3.8 minor defect defect that is not likely to reduce materially the usability of the considered product for

33、 its intended purpose, or that is a departure from established specification having little bearing on the effective use or operation of this product ISO 3534, see definition 3.9 sampling plan plan according to which one or more samples are taken in order to obtain information and possibly to reach a

34、 decision ISO 3534, see definition 3.10 limiting quality (LQ10) in a sampling plan, a quality limit which corresponds to a specified and relatively low probability of acceptance in this case 10 % probability of acceptance; it is the limiting lot quality characteristic that a lot of this quality woul

35、d occur When expressed as a per cent defective, it may be referred to as a lot tolerance per cent defective. ISO 3534, see definition 3.11 acceptable quality limit (AQL) quality limit which in a sampling plan corresponds to a specified but relatively high probability of acceptance It is the maximum

36、per cent defective (or the maximum number of defects per hundred units) that, for purposes of sampling inspection, can be considered satisfactory as a process average.

38、 bolts constituting the batch satisfy the requirements of this standard. 4.1.2 Conditions The acceptance tests are summarized in Table 3. They shall be performed on each batch. Table 1 specifies, the test method and sampling plan to be used for each test. Bolts from the batch to be tested shall be s

39、elected by simple random sampling. Each boIt may be submitted to several tests. The bolts to be subjected to destructive tests may be those on which non-destructive tests have been performed.
