Direct answer

Systems 1+ and 1 involve a notified product certification body under the relevant AVCP framework. Factory assessment and continuing surveillance support the product certification output; System 1+ additionally includes the prescribed audit-testing task. Neither route transfers the manufacturer's daily production responsibility.

Decision and evidence

Confirm the body's product and task scope. Link product assessment, FPC records, surveillance findings and the performance declaration to the same supplied product.

Technical basis

For construction products, the harmonised specification or ETA and intended use determine AVCP 1+, 1, 2+, 3 or 4. The number is a division of tasks, not a quality grade.

Practical questions

How should marking be assessed after a critical surveillance finding?

Consider performance and certificate effects under the procedure and body's decision. Identify affected scope from production and dispatch records. Complete corrections and notifications and follow mark-use restrictions. Closing a findings form alone may not explain product consequences.

Can a different intended use of the same product involve another system?

Review use and declared characteristics under the relevant framework. Different performance needs may affect task allocation. A general product name does not determine every application. Declarations, tests and body scope should reflect the route required for the intended use.
