32、whose function is to control the movement of water and water vapour through a wall, floor or roof NOTE They may have different permeabilities to water vapour depending on the specific use. In composite sheets the bitumen is the functional component. 3.3 carrier material incorporated into or onto the

33、 factory-made waterproofing sheet to ensure its stability and/or mechanical resistance 3.4 backing material incorporated onto the factory-made sheet without a permanent mechanical function 3.5 manufacturers limiting value, MLV value stated by the manufacturer to be met during testing. The manufactur

34、ers limiting value can be a minimum or a maximum value according to statements made under product characteristics of this document 3.6 manufacturers declared value, MDV value declared by the manufacturer accompanied by a declared tolerance 3.7 reinforced bitumen sheet factory made flexible layer of

35、bitumen, with internal or external incorporation of one or more carriers, supplied in roll form ready for use as a waterproofing sheet 3.8 oxidized bitumen straight run petroleum bitumen or a fluxed bitumen which has been hardened and rendered less temperature susceptible by blowing with air at high
