CE marking and Declaration of Performance for precast
Published:
Short answer: When accepting structural precast elements, read the product's Declaration of Performance (DoP) alongside the CE marking. Compare the declared values with the project specification through the relevant harmonised standard (EN 13369 together with product standards such as EN 1168 or EN 13225). If an item reads 'NPD' and the project requires it, write it into the contract. On site, the element code on the delivery note, shop drawing and declaration must match.
Which standard covers which product
EN 13369 sets the common rules for precast concrete products; hollowcore slabs fall under EN 1168 and linear structural elements under EN 13225. The document attached to an offer must reference the same standard as the element being ordered.
What to check in the declaration
Concrete compressive strength class, load-bearing capacity, fire resistance (REI), dimensional tolerance and durability class are the core declared items. Where an item reads 'NPD' (no performance determined) and the project requires it, that property must be written into the contract separately.
Factory production control
For structural elements under harmonised standards the manufacturer operates a factory production control (FPC) system subject to notified body surveillance. Test records and batch compressive test results should be available on request.
Document control on site
The element code on the delivery note, the code on the shop drawing and the product type in the declaration must match. Checking this three-way match is the first step at acceptance.
