4 Framework and structure
4.1 General

Where necessary the technical specification may be subdivided into several parts (e.g. EN XXXX-001,

EN XXXX-002, etc., where Part 001 is always the general part).

In such cases all general requirements should be incorporated in Part 001 (general part) and the specific

requirements in Part 002 onwards (specific parts). Annex A gives modified rules for the preparation of

technical specifications containing more than one part.

Published as ASD-STAN Technical Report at the date of publication of this document (see www.asd-stan.org).

EXAMPLE
4 Requirements
4.1 General requirements
(Add additional definitions, if necessary.)

4.1.1 Manufacturing schedule (complete with non-metallic material family if required)

The product shall be manufactured to fulfil the requirements of the relevant material standard and this

technical specification. In accordance with EN 9133, the manufacturer shall define the raw material,

processes and inspection requirements in a manufacturing schedule. Once approved, any

modifications to the manufacturing schedule shall be in accordance with EN 9133.
4.1.2 Traceability

All products shall be traceable to the raw material batches at all stages of manufacture and delivery.

Similarly, each raw material batch shall be traceable to all products at all stages of manufacture and

delivery.
4.1.3 Freedom from defects

All products shall be free from defects not complying with the requirements of the material standard

or order and this technical specification, or which may be prejudicial to the subsequent manufacture

and/or use of the products. (Add additional information if necessary.)
4.1.4 Health, safety and environment

It is the responsibility of the supplier to establish satisfactory health, safety and environmental

information to ensure conformity with any European, national or local laws/regulations.

The safety data sheet shall be available and shall be provided prior to qualification testing.

4.1.5 Dimensions

Dimensions and tolerances shall conform to the requirements of the order or drawing.

(Add additional information if necessary.)
4.1.6 Title as appropriate

Add any other relevant general requirements, with suitable subclause headings, as necessary (e.g. general

processing requirements).
Continue subclause numbering as required.
4.2 Technical requirements

The product shall satisfy the requirements of the relevant material standard and/or the order.

4.2.1 Required testing

Unless otherwise specified in the material standard, the test method and the test frequency for

screening, qualification testing and release testing are given in Annex A.

(Add any relevant general technical requirements as necessary using text and/or tables as desired.)

5.6.1 Test samples

It is essential that samples are identified with respect to the product and the batch from which they are

taken, therefore the first statement below is mandatory. It may also be necessary to impose requirements

on the condition of the samples prior to testing. Therefore one or more of the subsequent statements

shall be used as appropriate. Additional statements may be made as required.
EXAMPLE
4.2.2 Test samples

− Samples and associated test pieces shall be marked in such manner that their identity and orientation

(when appropriate) with respect to the product and the batch is maintained in a traceable manner.

− Samples taken from fully finished products (condition of use) shall not be further processed.

− Samples representing products in a condition other than the condition of use shall be processed in

accordance with the material standard before testing.
− Samples shall be tested in the as-supplied condition.
− Samples shall be tested in the fully cured condition.
4.2.3 Storage life/shelf life

The (material family) shall maintain all of its physical, chemical and mechanical properties within the

specification requirements for the period of time specified in the material standard, when stored under

the specified conditions.
(Insert subclause title) shall start from the date of manufacture.
4.2.4 Shoplife/work life/pot life/application time/out time

The product shall meet the physical, chemical and mechanical properties of the material standard for

a period of time known as the (insert subclause title) during shoplife/work life/pot life/application

time/out time under normal shop conditions.
These requirements will be met throughout the (insert subclause title).
4.2.5 Title as appropriate
Add any other relevant technical requirement
