43、 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. 4.1.2 Conditions The qualification tests summarized in Table 3 shall be performed on each
44、 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 subjected to each test
45、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 conditions. All o
46、r 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 acceptance tests. 4.
47、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 Purpose The purpose
48、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 summarized in Tab
49、le 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 destructive tests may be those on which non-destructive tests have been performed.
