The allocation of tests corresponding to the requirements of this standard is as follows: 4.1 Qualification. 4.1-1 Purpose- The purpose of
35、 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 summarised in table 3 shall be performed on each type and diameter of bolt. Proposed changes in manufa
36、cturing source or procedure shall be subject to the requirements of EN3041 - 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 as well as the method(s) ta be used are specified in t
37、able 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 obtained from parts of similar design, size and manufacturing conditions- All or part of these tests may also be performed for pro
38、duction 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. 4.1.3 Qualification test requirements and procedures.
39、 The qualification test. requirements and procedures shall be to the requirements of EN3042. 4-1.4 Qualified manufact.urers- A list of qualified manufacturers for specific standard parts is listed in CN/TR3040.

41、inty inherant to statistical sampling, that the bolts constituting the batch satisfy the requirements of this standard. 4.2.2 Conditions. Acceptance tests are summarised in table 3. They chal1 be performed on each batch. Table i specifies- the test method and sampling plan to be irsed for each test.
42、 Bolts from the batch to be tested shall be selected by simple random sampling. Each bolt may be submitted ta several tests. The bolts t.o 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 o
43、f quality system certification is to ensure that the manufacturer has demonstrated the acceptability of his quality system 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 qual
44、-ity system certification shall be to the requirements of SO9UQ2 and EN339- 4-4 Responsibilitv for inspection and tests. The manufacturer is responsible for the performance of all inspection and test requirements as specified herein. Each manufacturer will use their own or exceptionally. any other f
