3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
batches
quantity of finished rivets, manufactured using the same process, from a single material cast (single heat
of alloy), having the same standard number, diameter and length code, heat treated together to the same
specified condition and produced as one continuous run
3.2
rivet wire sample
length of wire, sampled at each end of the coil used for the manufacture of rivets of the batch
Note 1 to entry: The rivet wire samples undergo the same heat treatments as the rivets of the batch, at the same
time.

2 Published by: Society of Automotive Engineers (SAE), available at: https://www.sae.org/.
3.3
rivet sample
rivet sampled at random from the batch
3.4
crack
rupture in the material, which may extend in any direction and which may be intercrystalline or
transcrystalline in character
3.5
seam
longitudinal open surface defect
3.6
lap
surface defect caused by folding over metal fins or sharp corners and then forming them into the surface
3.7
cold shut
doubling over of metal, this may occur during the cold heading operation
3.8
double ring
the discontinuity is wide but shallow and open to the surface at both ends of the discontinuity
3.9
pit
small cavity in a metal surface caused by non-uniform electro deposition or by corrosion
3.10
inclusion
non-metallic particles originating from the aluminium alloy making process
Note 1 to entry: They can exist as discrete particles or strings of particles extending in a longitudinal direction.
3.11
material separation
any loss of material from preformed head induced by installation of the rivet
3.12
defect
non-fulfilment of a requirement related to an intended or specified use
3.13
major defect
defect that is likely to result in a failure or to reduce materially the usability of the considered product for
its intended purpose
3.14
minor defect
defect that is not likely to reduce materially the usability of the considered product for its intended
purpose, or that represents a departure from established specification having little bearing on the
effective use or operation of this product
3.15
hydrogen porosity (high temperature oxidation)
racks and fixtures used shall be constructed to preclude entrapment of water
Note 1 to entry: Ammonium fluorborate or equivalent can be used in air furnace as necessary.
3.16
blistering
defect in the metal on or near the surface, resulting from expansion of gas or entrapped lubricant from
forging process in a sub-surface zone
3.17
eutectic melting
mixture of different phases with eutectic composition, which melts below the solidus temperature of the
alloy
Note 1 to entry: Eutectic melting is characterised by small rosettes in the microstructure or by outlined grain
boundaries, particularly at triple intersections. It can occur when raw material is not homogenized or worked
properly
3.18
intergranular corrosion
selective corrosion attack along grain boundaries or closely adjacent regions without appreciable attack
of the grains
3.19
sampling plan
plan according to which one or more samples are taken from a batch in order to do acceptance tests to
demonstrate conformity of the batch
3.20
acceptable quality level
AQL
maximum percent defective (or the maximum number of defects per hundred units) that, for purposes of
sampling inspection, can be considered satisfactory as a process average
Note 1 to entry: Variant: quality level, which in a sampling plan corresponds to a specified but relatively high
probability of acceptance.
4 Quality assurance
4.1 General
4.1.1 Approval of manufacturers
The manufacturer’s operations shall be an approved production organization 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 purpose of these procedures is to ensure that a manufacturer has a quality management system in
place and is capable of continuous production of solid rivets complying with the specified quality
requirements.
The Certification Authorities, or their appointed representative, who may be the prime contractor, shall
grant the approval of the manufacturer.
4.1.2 Acceptance of solid rivets
The purpose of acceptance inspection and tests of a solid rivet is to check, as simply as possible, using a
method which is inexpensive but the most representative of the actual conditions of use, with the
uncertainty inherent in statistical sampling, that the solid rivets satisfy the requirements of this
document.
Acceptance inspections and tests shall be carried out by the manufacturer, or under his responsibility.
The manufacturer is responsible for the quality of the solid rivets manufactured to this specification and
adherence to this specification.
4.2 Acceptance inspection and test conditions
Acceptance inspections and tests (requirements, methods, numbers of solid rivets) are specified in
Table 1. They shall be carried out on each batch. Solid rivets shall be selected from the batch to be tested
by random sampling.
Each solid rivet may be submitted to several inspections or tests, provided that none of its characteristics
has been altered during any of these inspections or tests.
The solid rivets to be subjected to destructive inspections or tests may be those on which non-destructive
inspections or tests have been carried out.
In this case, the attribute(s), which caused the rejection, shall be verified using a sample of twice the
normal size with the same AQL.
On demand of procurement quality department the sampling can be increased from normal control to
reinforced
