Assessment and Verification of Constancy of Performance (AVCP)

In order to make the CE marking for a construction product, this product has to be subject to a harmonised standard (hEN), or have a valid European Technical Assessment (ETA) available.

From there, the fundamental tasks to make are:

  • Determination of the product-type on the basis of type testing, type calculation, tabulated values or descriptive documentation of the product.
  • Have a factory production control (FPC) system implemented.

The assessment systems to apply to the product or product families, are established in the article 28 and annex V of the regulation, depending on how the product affects to the people end environment security and health.

In the table below, it is shown the tasks involving the manufacturer and the tasks involving the notified body, in order to perform the assessment and verification of constancy of performance.
