TS EN 9133

TS EN 9133 defines a common approach for qualifying aerospace standard parts and is intended to help ensure that these parts meet the requirements of the technical specifications that reference them. It also addresses the need for manufacturers of such parts to operate with a quality management system at least equivalent to EN 9100, linking part qualification with the maturity of the manufacturing organisation.

What counts as an aerospace standard part?

In aerospace practice, a standard part is a defined, repeatable component that is not unique to one design application. Fasteners, washers, rivets, nuts and similar items are typical examples. Qualification for these parts is not only about dimensional conformity; it also depends on traceability, process consistency and the capability of the manufacturer’s quality controls.

Why a uniform qualification method matters

The standard provides a consistent framework so that different technical specifications and supply chains can rely on the same basic qualification logic. In general technical terms, this means the suitability of a part is assessed against the specification that calls it up, while also considering how the part is controlled, produced and verified. That combination is especially important in aerospace, where standard parts are small components but can have a significant effect on assembly integrity and system reliability.

• It covers qualification procedures for aerospace standard parts.
• It is aimed at conformity with the requirements of the calling technical specifications.
• It includes the expectation of a quality management system at least equivalent to EN 9100 for manufacturers.
• It establishes a basic uniform method for qualification.
