NBN EN 13304:2009

This European Standard provides a framework for the specification of oxidised bitumens used mainly in
roofing, waterproofing, adhesives and thermal and phonic insulations.
Within Europe several types of oxidised bitumens are used and, dependent on climatic conditions, type of
building construction and traditional practices, different grades may be used for the same purpose. The
framework given in this European standard provides a basis for quality agreements to be established between
supplier and client.
The oxidised bitumen products are graded by a combination of the values of ring and ball softening point, and
penetration at 25 °C, expressed as multiples of 5.
