3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
production batch
quantity of finished parts fabricated by the same process from a single material cast (single heat of alloy),
having the same basic part number and diameter, heat treated together to the same specified condition and
produced as one continuous run
3.2
inspection lot
quantity of parts from a single production batch of the same part number which completely defines the part
3.3 Surface discontinuities
3.3.1
crack
rupture in the material which may extend in any direction and which may be intercrystalline or
transcrystallyne in character
3.3.2
seam
longitudinal surface defect in the form of an unwelded open fold in the material

lap
surface defect caused by folding over metal fins or sharp corners and then rolling or forging them into the
surface

have the same probability of being chosen
[SOURCE: ISO 3534, see definition]
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

4 Certification and quality 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 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 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 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 acceptance
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 Purpose
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 summarized 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 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 the manufacturer has demonstrated the
acceptability of his quality system and his ability for continuing production of parts to this standard, to the
required limit of quality.
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.
