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.

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
with 4.2 for the implementation of these inspection and test requirements.
4.4 Inspection and test report
A test report showing actual numerical values shall be provided at the purchaser’s option as part of the
terms of the purchase order.
