EN 13305:2009 – Bitumen and bituminous binders – Framework for specification of hard industrial bitumens

1 Scope
This European Standard provides a framework for the specification of hard industrial bitumens used mainly in flooring, varnishes, mineral rubber, roofing and mastic.
Within Europe several types of hard industrial bitumen are used, and dependent upon 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 hard industrial bitumen products are graded by the limits of the ring and ball softening point values,expressed as multiples of 5, and are characterised by an H in front of the values.

3 Properties and test methods
Hard industrial bitumens are specified according to the limits of softening point values. The specification of hard industrial bitumens with stated values shall be made according to the rules given in Table 1:
4 Typical grades
Typical grades for hard industrial bitumen are:
H 80/90;
H 85/95;
H 90/100;
H 100/110;
H 155/165.
EXAMPLE H 85/95 means that the softening point of the product is between 85 °C and 95 °C.
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.
