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