European foreword
This document (prEN 3043:2022) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 3043:2008.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
1 Scope
This document specifies the technical and quality assurance requirements for externally threaded
fasteners in material FE-PA92HT (A286) of tensile strength class 900 MPa at room temperature,
maximum test temperature of material 650 °C.
The externally threaded fasteners specified here may be manufactured by machining from bar or by
forging at the manufacturer’s option, if forged there is no requirement for control of grain flow.
Primarily for aerospace applications it is applicable to such externally threaded fasteners when
referenced on the product standard or drawing.

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

Published as ASD-STAN Standard at the date of publication of this standard by AeroSpace and Defence
Industries Association of Europe – Standardization (ASD-STAN) (www.asd-stan.org)
3.2
inspection lot
consists of parts from a single production batch of the same part number which completely defines the
part
3.3
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
longitudinal surface defect in the form of an unwelded open fold in the material
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
inclusion
non-metallic particles originating from the material making process, which may exist as discrete particles
or strings of particles extending longitudinally
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
[SOURCE: ISO 3534-2:2006, 1.3.4 – modified]
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
[SOURCE: ISO 9152:1998, 3.12 – modified]
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
[SOURCE: ISO 9152:1998, 3.13 – modified]
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

3.10
limiting quality LQ
in a sampling plan, a quality level which corresponds to a specified and relatively low probability of
acceptance — in this case 10 % probability of acceptance. It is the limiting lot quality characteristic that
a lot of this quality would occur
Note 1 to entry: When expressed as a per cent defective, it may be referred to as a lot tolerance per cent defective.
[SOURCE: ISO 9152:1998, 3.15 – modified]
3.11
acceptable quality level
quality level 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.
[SOURCE: ISO 9152:1998, 3.16 – modified]
3.12
finished part
part ready for use, inclusive of any possible treatments and/or surface coatings, as specified in the
dimensional standard or drawing
4 Certification and quality assurance
4.1 Acceptance
4.1.1 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.
4.1.2 Conditions
Acceptance tests are summarised in Table 2. 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.
4.2 Quality system certification
4.2.1 Purpose
The purpose of quality system certification is to ensure that the manufacturer has demonstrated the
acceptability of their quality system and their ability for continuing production of parts according to this
standard, to the required level of quality.
4.2.2 Requirements and procedure, quality management system
The requirements and procedures for quality system certification shall be according to the requirements
of EN 9100.
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.
4.3 Responsibility 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 facilities approved in accordance
