What is BS EN 12593 - Fraass breaking point of bitumen and bituminous binders about ?
BS EN 12593 is the European standard on bituminous binders that discusses the Fraass breaking point at which a film of the bituminous binder of a specified and uniform thickness will break under defined loading conditions.
BS EN 12593 specifies a method for determining the Fraass breaking point which measures the brittleness of bitumen and bituminous binders at low temperatures.
Who is BS EN 12593 - Fraass breaking point of bitumen and bituminous binders for ?
BS EN 12593 on bitumen and bituminous binders is useful for:
- Manufacturers of bituminous products
- Manufacturers of waxes and petroleum products
- Manufacturers of binders and sealing materials
Why should you use BS EN 12593 - Fraass breaking point of bitumen and bituminous binders ?
The Fraass breaking point is the temperature at which the first crack appears in the coating of a thin, flat steel plaque, flexed under descending temperatures.
BS EN 12593 provides the requirements for laboratory apparatus to test samples of the bituminous binder.
BS EN 12593 guides you through the sampling and sample preparation including test plate preparation and coating test plates.
BS EN 12593 specifies the test procedure and test conditions as well as the measurement of binders through manual or semi-automatic apparatus and fully automatic apparatus.
Determination and expression of results of the Fraass breaking point are set out through BS EN 12593.
The repeatability limit and reproducibility limit of the Fraass breaking point are outlined in BS EN 12593.
Overall, BS EN 12593 allows you to manufacture bituminous binders while ensuring bitumen brittleness and evaluating the anti-cracking capabilities of the binder at low temperatures.
Bitumen and bituminous binders can thus be used in construction to examine the consistency, gradation, viscosity, temperature susceptibility, and safety of the building.
What’s changed since the last update?
BS EN 12593:2015 supersedes BS EN 12593:2007. BS EN 12593:2015 includes some technical changes with respect to BS EN 12593:2007. These include:
- The standard has been revised due to a normative reference to mercury thermometers.
- Regarding sample preparation the procedure for press-application of the sample has been deleted, and the maximum sample preparation time of 10 min has been moved from an informative note to the normative text
- The explanation for the determination of Fraass breaking.
