This European Standard specifies a procedure for determining the watertightness of polymer modified bituminous thick coatings for waterproofing (that is the resistance to hydraulic pressure). This is a test procedure for polymer modified bituminous thick coatings intended for use in pressure application, for example, pressured water in soil. A test specimen is subjected to a specified water pressure for at least 24 h against a disk containing four slots of specified form and dimensions. The test specimen is observed to establish whether it remains watertight. The Committee responsible for this standard is NA 005-02-19 AA "Kunststoffmodifizierte Bitumendickbeschichtung zur Bauwerksabdichtung (SpA zu CEN/TC 361)" ("Polymer modified bituminous thick coatings for waterproofing (Mirror Committee of CEN/TC 361)") at DIN.
