EN 13303:2009 – Bitumen and bituminous binders – Determination of the loss in mass after heating of industrial bitumen
1 Scope
This European Standard specifies a method for the determination of the loss in mass of industrial bitumen after heating. The method is used to detect volatile components.
NOTE The users of the method are encouraged to gather comparative information on binders using this standard,EN 13303 and EN 12607-2 [1] at 163 °C to facilitate the withdrawal of EN 13303 at the next systematic review.
WARNING — The use of this standard may involve hazardous materials, operations and equipment.
This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

3 Terms and definitions
For the purposes of this document, the following term and definition applies.
3.1
loss on heating
ratio in between the loss in mass after heating a sample and its initial mass, expressed as a percentage of the latter
4 Principle
A weighed sample is heated for a specified time at a specified temperature and is re-weighed at the conclusion of the heating period.
5 Apparatus
5.1 Oven, electrically heated and conforming to the performance requirements for ovens ventilated by natural convection and for operating temperatures up to 180 °C.
The oven shall be rectangular with minimum interior dimensions of 330 mm in each direction. The oven shall have in front a tightly fitting hinged door, which shall provide a clear opening, substantially the same as the interior height and width of the oven. The door may contain a window with dimensions of at least 100 mm x 100 mm, and with two sheets of glass separated by an air space, through which a vertical thermometer (5.3) located as specified in 7.8, may be read without opening the door, or the oven may be provided with an inner glass door through which the thermometer may be observed on opening the outer door momentarily.
