Regulations
Standards and regulations define the type and frequency of lab tests required to characterise the aggregates produced in terms of performance, thus dividing them into geometric, physical, chemical, durability and environmental test.
Based on the applicable standards, the aggregates manufacturer will:
- 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)”
- 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.
The Ministerial Decree enforced on April 24th, 2007 and of November 16th, 2009 defines the required features to be declared for aggregates marketed in Italy and the CE marking with +2 certification level became mandatory for aggregates used in structural works. Furthermore, the enactment of Ministerial Decree of 14/01/2008 and subsequent amendments confirmed the +2 certification level as mandatory for aggregates used for structural concrete production since July 1st, 2009. A third certification body is therefore required to perform the preliminary check and to monitor production process control.
As to recycled aggregates, more specifically, the Ministerial Decree 203/2003 requires public administrations to use at least 30% recycled materials for road and environmental works and fillings in general out of the total material amount.
The Circular letter No. 5205 of 15/07/2005 issued by the Ministry of Environment states the performance-related features of recycled aggregates, depending on the possible use, to be tested at least every 3,000 cubic metre.
The Ministerial Decree No. 186 of 05/04/2006 states – under point 7.1.4 – that the features of secondary raw materials for buildings (both public and private) must be compliant with Annex C of the Circular Letter of the Ministry of Environment, Land and Sea No. 5205 of July 15th, 2005.
The Resolution of the Provincial Council No. 1333 of June 24th, 2011 “Guidelines and technical standards for the production of recycled aggregates” has more precisely defined the use of these materials for the province of Trento.
With the Resolutions of the Provincial Council No. 1030 of September 27th, 2016 and 398 of April 11th, 2017 the province of Bolzano has also provided engineers, designers and companies with clear provisions on the use of recycled aggregates.

Our services
We have a UNI EN ISO 9001 certified test lab that can perform all tests required by harmonised standards for aggregates and by the main tender specifications.
The lab is equipped with all of the necessary resources to collect samples directly, in compliance with the UNI EN 932-1 standard. Test reports are sent within 30 days after collecting the samples, except for cases where other specific tests are required.
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.
