EN 13304:2009 – Bitumen and bituminous binders – Framework for specification of oxidised bitumens
1 Scope
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.

3 Properties and test methods
The specification of oxidised bitumens shall be made according to the rules given in Table 1:
4 Typical grades
Typical grades for oxidised bitumens are:
85/25; 85/40; 95/25; 95/35; 100/40; 105/35; 110/30; 115/15.
EXAMPLE 85/25 means that the ring and ball softening point of the product is between 80 °C and 90 °C and penetration between 20 x 0,1 mm and 30 x 0,1 mm.
NOTE This list does not imply that all grades are available in all countries, neither is it intended to be comprehensive or limiting. Other grades may be supplied in accordance with the local practices and by agreement between client and supplier.
