The granite production process


Production controls

Like any building product, natural stone requires certain controls to ensure its qualities.
These controls are the responsibility of the product manufacturer and are linked to obtaining the mandatory EC Mark.

Since 2003, manufacturers of natural stone products are required to perform a number of production controls, linked to obtaining the EC MARK required for the movement of stone building products in the EU.
To do so, the manufacturer must implement a systematic Factory Production Control (FPC), consisting, in summarized form, of:

  • Performing a series of laboratory tests to find out the physical-mechanical properties of the material. 
  • Controlling production in terms of size.
Production controls are described in two documents to be provided by the manufacturer to the client: a Declaration of conformity of the product with the standard and a Label identifying the EC Mark.
