Natural stones and stone agglomerates
Mandatory CE marking with level 4 certification (manufacturer’s self-declaration) for stone products in general, first introduced in 2003 for some products (outdoor floors) was completed in 2006 for the remaining stone products (indoor floors, wall coatings, etc.) to include the whole commercial range of stone materials such as porphyry, granite, marble and limestone.
CE marking was made mandatory at a later stage also for stone agglomerates for floors (since January 2010) and wall coatings (since August 2015).

Regulations
Standards define both the type and frequency of lab tests to determine chemical, physical and mechanical parameters required for product compliance.
Based on the applicable regulations, manufacturers of natural stone or agglomerates shall:
- Supply a well documented monitoring system for the production process in compliance with the applicable harmonised standards; such documents are defined as “Factory Production Control (FPC) documents”
- Carry out preliminary tests and plan a regular monitoring plan;
- Classify and declare – based on the test results – product features in compliance with the standards.
Our services
We have a UNI EN ISO 9001 certified test lab that can perform all tests required by harmonised standard for natural stones and stone aggregates and by the main tender specifications.
Samples are usually provided by the client according to the number and size required for every test type.
A customised software application makes it possible to keep the cycle and the results monitored thanks to a database to perform statistic checks, also providing updates to the required CE documents, which will be sent for free as a PDF file in case at least a complete test cycle is ordered. The PDF file can be reproduced or directly transferred to corporate transport documents.
Our technical staff can provide you with all of the necessary documents for the CE marking, material technical sheets as well as information on all specific standards for the sector and assist you during testing and for any claims.
We do also perform lab and building-site tests to determine slip-wear resistance in compliance with the British Ceramic Research Association Ltd. (B.C.R.A.) Rep. CEC.6/81 method, also known as “Tortus Test”. The Ministerial Decree 13/89 on removing architectural barriers also provides for this method – under paragraph 8.2.2 – based on which the law defines an objective value in order to assess whether a surface is safe in terms of “slipping risk”.
Find the list of tests carried out on natural stones either directly or through associated bodies.

Carrying out lab tests means – for the manufacturer – preparing samples in the required amount and size for every single test.
Samples must be prepared with the right finishing required for the individual tests, with parallel surfaces and perpendicular faces (planarity +/- 0,1 mm).
