26、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 them into the surface 3.3.4 inclusion non-metallic particles originating from the material making process. They may exist as discrete particles or strings

28、inition 3.6 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 ISO 3534,

29、see definition 3.7 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 ISO 3534, see definition EN 3302:20076 3.8 minor defect a defect that is not likely to reduce materially the us

30、ability 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 ISO 3534, see definition 3.9 sampling plan a plan according to which one or more samples are taken in order to obt

31、ain information and possibly to reach a 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 charact

32、eristic that a lot of this quality would 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 acceptance quality limit (AQL) a quality limit which in a sampling plan corresponds to a specified but relatively high pr

33、obability 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. ISO 3534, see definition 3.12 finished bolt a bolt ready for use, inclusive of any possibl

35、y assurance 4.1 Qualification 4.1.1 Purpose The purpose of qualification tests is to ensure that the bolt design and bolt manufacturing conditions allow the bolt to comply with the requirements of this standard. EN 3302:20077 4.1.2 Conditions The qualification tests summarized in Table 3 shall be pe

36、rformed on each type and diameter of bolt. Proposed changes in manufacturing source or procedure shall be subject to the requirements of EN 9133. 25 bolts selected from a single inspection lot by simple random sampling shall be subjected to the qualification tests. The number of bolts to be subjecte

37、d to each test as well as the method(s) to be used is specified in Table 1. The tests to be applied to each bolt are shown in Table 4. The test programme may possibly be reduced, this decision will be based on the comparison of results obtained from parts of similar design, size and manufacturing co

38、nditions. All or part of these tests may also be performed for production acceptance, when a reinforced inspection seems to be necessary, or to survey bolts that have not proved satisfactory in use. In that case, the sample to be subjected to these tests is the same as that used for production accep

39、tance tests. 4.1.3 Qualification test requirements and procedures The qualification test requirements and procedures shall be to the requirements of EN 9133. 4.1.4 Qualified manufacturers A list of qualified manufacturers for specific standard parts is listed in TR 3040-1. 4.2 Acceptance 4.2.1 Purpo

40、se The purpose of acceptance tests is to check, as simply as possible, by a method representative of actual use conditions, with the uncertainty inherent to statistical sampling, that the bolts constituting the batch satisfy the requirements of this standard. 4.2.2 Conditions Acceptance tests are su

41、mmarized 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 selected by simple random sampling. Each bolt may be submitted to several tests. The bolts to be subjected to destruct

42、ive tests may be those on which non-destructive tests have been performed. 4.3 Quality system certification 4.3.1 Purpose The purpose of quality system certification is to ensure that the manufacturer has demonstrated the acceptability of his quality system and his ability for continuing production

43、of parts to this standard, to the required limit of quality. EN 3302:20078 4.3.2 Requirements and procedure The requirements and procedures for quality system certification shall be to the requirements of ISO 9000 and EN 9100. 4.4 Responsibility for inspection and tests The manufacturer is responsib

44、le for the performance of all inspection and test requirements as specified herein. Each manufacturer will use their own or exceptionally, any other facilities approved in accordance with 4.1 and 4.2 for the implementation of these inspection and test requirements. 4.5 Inspection and test report A t

45、est report showing actual numerical values shall be provided at the purchasers option as part of the terms of the purchase order. 5 Technical requirements and test methods Table 1 Technical requirements and test methods Clause Characteristic Requirement Inspection and test method Q/A aSample size 5.
