3 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
batch
quantity of finished parts, of the same type and same diameter, produced from the same material
obtained from the same melt, manufactured in the course of the same production cycle, following the
same manufacturing route and having undergone all the relevant heat treatments and surface
treatments
Minimum tensile strength of the material at ambient temperature.
Maximum test temperature of the parts.
Published by: ASTM National (US) American Society for Testing and Materials http://www.astm.org.
3.2
inspection lot
quantity of parts from a single production batch with 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
transcrystalline in character
3.3.2
seam
open surface defect
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
inclusions
non-metallic particles originating from the material manufacturing process
Note 1 to entry: These particles may be isolated or arranged in strings.
3.4
test temperature
ambient temperature unless otherwise specified
3.5
simple random sampling
taking of n items from a population of N items in such a way that all possible combinations of n items
have the same probability of being chosen
3.6
critical defect
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
3.7
major defect
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
3.8
minor defect
defect that is not likely to reduce materially the usability 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
3.9
sampling plan
plan according to which one or more samples are taken in order to obtain information and possibly to
reach a decision
3.10
Limiting Quality
LQ
quality limit which, in a sampling plan, corresponds to a specified 10 % probability of acceptance
3.11
Acceptance Quality Limit
AQL
quality limit which, in a sampling plan, corresponds to a specified but relatively high probability of
acceptance
Note 1 to entry: 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.
3.12
finished bolt
bolt ready for use, inclusive of any possible treatments and/or surface coatings, as specified in the
product standard or definition document
3.13
definition document
document specifying all the requirements for finished bolts
4 Quality assurance
4.1 Qualification
The manufacturer’s operations shall be an approved production organisation for aerospace products
and shall demonstrate that it has implemented and is able to maintain a quality management system
(e. g. according to EN 9100 or an equivalent aerospace accepted and established quality management
system).
The qualification procedure for aerospace standard products (e.g. according to EN 9133 or an
equivalent aerospace accepted and established qualification procedure) shall be used and documented
according to the specified tests if not otherwise agreed between customer and supplier.
The product qualification shall be performed to the process as defined in e. g. EN 9133 to achieve a
qualification approval from the controlling Certification Authority (CA).
Qualification inspections and tests (requirements, methods, numbers of bolts) are specified in Table 1.
They shall be carried out on:
— each type and diameter of bolt;
— 25 bolts selected from a single inspection lot by simple random sampling.
The test programme may possibly be reduced, or the qualification of a bolt be granted without
inspection or testing. Any such decision shall be based on the results obtained on similar types and
diameters of bolts provided that the design and manufacturing conditions are identical.
Table 2 indicates the allocation of bolt samples for the inspections and tests.
4.2 Acceptance
4.2.1 Purpose
The purpose of acceptance inspections and 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 inspections and tests (requirements, methods, numbers of bolts) are specified in Table 1;
they shall be carried out on each batch. Bolts from the batch to be tested shall be selected by simple
random sampling.
Each bolt may be submitted to several inspections or tests.
If a more stringent inspection is deemed necessary, all or part of the qualification inspections and tests
may be performed during the acceptance inspection and testing. In this case, the number of bolts
submitted to these inspections and tests is the same as that submitted for qualification inspection and
tests.
4.2.3 Responsibility
Acceptance inspections and tests shall be carried out by the manufacturer, or under his responsibility.
4.2.4 Inspection and test report
A test report showing actual numerical values shall be provided if specified in the purchase order.
