TS EN ISO/IEC 17050-1

TS EN ISO/IEC 17050-1 addresses the general requirements for a supplier’s declaration of conformity and focuses on how conformity with specified requirements is stated for an object. The standard provides a common framework for the declaration itself rather than for the object’s design or performance requirements.

What a supplier’s declaration is used for

In conformity assessment, a supplier’s declaration is a first-party statement: the supplier declares that the object meets identified requirements. In general technical practice, this type of declaration is supported by records, test evidence, inspection data, or other objective information so that customers and other interested parties can understand the basis of the claim. It is especially relevant where a clear, direct statement of conformity is needed in purchasing, contracting, or supply-chain communication.

Objects covered by the standard

• products
• processes
• management systems
• persons
• bodies

The standard is sector-neutral, so it is not limited to one industry or technology area. Its value lies in creating a consistent structure and terminology for the declaration, helping distinguish the act of declaring conformity from the technical evaluation used to reach that conclusion. In practice, that distinction matters because the declaration should clearly identify the applicable requirements and the object to which they apply.

As a current TS EN ISO/IEC 17050-1 edition, this document is useful for anyone who needs a disciplined, internationally recognized way to present a supplier’s conformity statement. It supports clarity, traceability, and comparability in conformity assessment without turning the document into a product-specific test method.
