Acoustic Vibration Analysis

The laboratory uses hi-tech equipment and its staff consists of technicians with the qualification of Technical Expert in Acoustics who take part in many working groups of the UNI acoustic commission.

The acoustics vibration testing closely follows the standards recommended by the main international standards bodies like UNI, EN, ISO, DIN, NF, BSI and ASTM.

The Laboratory appears on the list of notified bodies by the European Commission that are authorised to perform initial type testing for CE marking for the purposes of the Regulation (EU) No 305/2011 (CPR) and it is accredited by ACCREDIA, according to the UNI CEI EN ISO/IEC 17025 “General requirements for the competence of testing and calibration laboratories”, for laboratory tests regarding airborne and impact sound insulation, sound absorption and power sound.
