It is imperative for Acoustic Barriers to be tested not only for Noise Abutment Properties but as well as Physical Properties as poor physical properties would make them a Safety Hazard on Road Side Installations, it is for this reason that the European Union mandates testing to both:
EN-1793 - Acoustic Properties
EN-1794- Physical Properties
as a mandatory requirement to be placed in the European Union. The EN-1793 and EN-1794 standards have been adopted by many countries outside the European Union as well.
The PANACOR Systems are CE Certified and comply with the standards set out in EN-1793 and EN-1794.
