CPR (Retention (EU) No 305/2011-CPR) is a new building products regulation issued by the European Union on March 9, 2011, replacing the old Building Products Directive (89/106/EEC-CPD) and notifying that CPR will enter the mandatory enforcement phase in July 2013. The new regulations will make the procedures and technical language for building products entering the EU market more transparent, rigorous, and precise, ensuring that EU users (architects, engineers, construction personnel) choose the most suitable products for the intended use of building projects.
