CE marking: natural stone products

In January 2013 the update of the three framework standards that regulate the product qualification for Natural Stone Slabs, Cubes and Curbs came into force for External Flooring.

We list below the harmonized standards of reference for the sector of natural stones and agglomerated stone products, divided according to the intended use. In blue are highlighted the natural stone products that require the intervention of the Notified Body to obtain the CE marking.

The procedure that the manufacturer must follow to affix the CE mark to its natural stone product varies according to the type of product itself and its destination of use.

The standards define both the type of chemical, physical and mechanical tests to be performed and their recurrence over time - both necessary requirements to certify the conformity of natural stone products. 

In general, the Manufacturer is required to:

Certimac’s experts CE - CPR marking work alongside manufacturers of natural stone products throughout the certification process, helping them to simplify the process of compliance with national and international standards and building codes, providing time-efficient, cost-effective and regulatory compliant testing and certification.

In particular, in its role as Notified Body - n. 2685 CPR (EU) 305/2011 for the issue of Test and Classification Certificates, Certimac carries out all the third party tasks assigned to it in the process of assessing and verifying the performance requirements and constancy of performance and for which it has been notified by the Ministries in charge, determining the characteristics or performance of construction materials or products in accordance with the requirements of current regulations.

Certimac carries out the analyzes and laboratory tests necessary for the Evaluation and Verification of Constancy of Performance - VVCP - and for the issue of certificates of constancy of performance.

Modular tiles in natural stone (UNI EN 12057) and slabs for cladding in natural stone (UNI EN 1469) are among the products classified with the VVCP 3 system. In these cases the product must be tested by a Notified Body (notified laboratory).

In its role as Notified Body for products classified with the VVCP 3 system out of thirty harmonized standards, Certimac operates as a Notified Test Laboratory with the task of measuring, examining, verifying and certifying the characteristics or performance of natural stone products.

For natural stone products that fall within the VVCP 4, Certimac can collaborate with the Manufacturer for the execution of the initial type tests and controls of the production process in the factory for the CE marking pursuant to CPR (EU) 305/2011.
