The allocation of te
31、sts corresponding to the requirements of this standard is as follows: 4.1 Qualification. 4.1.1 4.1.2 4.1.3 4.1.4 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. Conditions
32、. The qualification tests summarised in table 3 shall be performed on each type and diameter of bolt. Proposed changes in manufacturing soiirce ar procedure shall be subject to the requirements of EN3041. - 25 bolts selected from a single inspection lot by simple random sampling shall be subjected t
33、o the qualification tests. The number of bolts to be subjected t.o each test as well as the method(s1 to be used are specified in table i- The tests to be applied t.o each bolt are shown in table 4. The test programme may possibly be reduced, this decision will be based on the comparison of results
34、obtained from parts of similar design, size and manufacturing conditions. 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 subjec
35、ted to these tests is the same as that used for production acceptance tests. Qualification test requirements and procedures. The qualification test requirements and procedures shall be to the requirements of EN3042. Qualified manufacturers. A list of qualified manufacturers for specific standard par
36、ts is listed in CN/TR3040. AECMA PREN2582 87 10L232L 0003584 L W EN2582 Page 7 4.2 Acceptance. 4.2.1 Purpose. The purpose of acceptance tests is to check, as simply as possible, by a method representative of actual use conditions, with the uncertainty inherant to statistical sampling, that the bolts
37、 constituting the batch satisfy the requirements of this standard. 4.2.2 Conditions. Acceptance tests are summarised in table 3. They shall be performed on each batch. Table I specifies, the test method and sampling plan to be used for each test. Bolts from the batch to be tested shall be selected b
38、y 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 - 4.3 Quality system certification. 4 - 3 - 1 Purpose - The purpose of quality system certification is to ensure that
39、the manufacturer has demonstrated the acceptability of his quality syst.em and his ability for continuing production of parts to this standard to the required level of quality- 4.3.2 Requirements and procedure. The requirements and procedures for quality system certification shall be to the requirem
40、ents of IS09002 and EN3039. 4.4 Responsibility for inspection and tests. The manufacturer is responsible far the performance of all inspection and test requirements as specified herein. Each manufacturer will use their own or exceptionalIy, any other facilities approved in accordance with 4.1 and 4.
