Assembly for mechanical tests.17

1) Minimum tensile strength of the material at ambient temperature. 2) Published as AECMA Prestandard at the date of publication of this standard.

3.2.1 crack rupture in the material which may extend in any direction and which may be intercrystalline or transcrystalline in character 3.2.2 seam open surface defect 3.2.3 lap surface defect caused by folding over metal fins or sharp corners and then compressing them into the surface 3.3 test temperature ambient temperature, unless otherwise specified 3.4 simple random sampling the taking of 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
3.5 critical defect a defect that, according to judgement and experience, is likely to result in hazardous or unsafe conditions for individuals using, maintaining, or depending upon the considered product, or that is likely to prevent performance of the function of a major end item 3.6 major defect a defect other than critical, that is likely to result in a failure or to reduce materially the usability of the considered product for its intended purpose
3.7 minor defect a defect that is not likely to reduce materially the usability of the considered product for its intended purpose, or that is a departure from established specification having little bearing on the effective use or operation of this product 3.8 sampling plan a plan according to which one or more samples are taken in order to obtain information and possibly to reach a decision
3.9 limiting quality in a sampling plan, the quality limit which corresponds to the specified 10 % probability of acceptance 3.10 acceptable quality limit (AQL) a quality limit which in a sampling plan corresponds to a specified but relatively high probability of acceptance It is the maximum 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.
