Under the provisions of the Construction Products Directive (89/106/EEC), Member States retained the competence to establish performance requirements for construction products, but only on condition that they did not impede the free movement of CE-marked products.
Ehitusmaterjalide direktiivi (89/106/EMÜ) kohaselt on liikmesriikide pädevuses kehtestada nõuded, millele ehitusmaterjalid peavad vastama, aga seda üksnes juhul, kui need ei takista CE-vastavusmärgisega kaupade vaba liikumist.
