Many construction products are of major importance to construction works. Therefore, it may be necessary to subject certain construction products to an independent third party assessment and/or verification.
However, not all construction products need the same form of assessment and/or verification. Not all the same construction products have the same signification for construction works.
Third-party assessments and manufacturers' tasks are therefore categorised into various systems, known as systems for assessment and verification of the constancy of performance of construction products (hereafter the AVCP-systems). There are five systems which describe manufacturers' tasks, and what tasks are to be carried out by a third party.
An overview of these AVCP systems can be found in "related links" on the right.
