What is BS EN 13399 - Storage stability of modified bitumen about?
BS EN 13399 is a European standard on bitumen and bituminous binders that discusses the storage stability of bitumen.
BS EN 13399 specifies a method for measuring the storage stability of modified bitumen at high temperatures.
Who is BS EN 13399 - Storage stability of modified bitumen for?
BS EN 13399 on bitumen and bituminous binders is useful for:
- Manufacturers of bituminous products
- Manufacturers of binders and sealing materials
- Manufacturers and suppliers of thermoplastic polymers
Why should you use BS EN 13399 - Storage stability of modified bitumen?
Modified bitumen and, in particular, polymer-modified bitumen, which consist of mainly bitumen and at least one additional agent, are known to display phase separation under certain conditions.
BS EN 13399 provides the laboratory apparatus requirements and test procedure on modified bitumen to determine storage stability.
Moreover, BS EN 13399 assist you in manufacturing bitumen by ensuring storage stability to evaluate the stability and compatibility of the modifier in the binder at high temperature.
As a result, you can procure high-quality binder bitumen for the structure with excellent water-proofing properties which are widely used for making roofing products along with a range of other household and industrial applications.
What’s changed since the last update?
BS EN 13399:2017 supersedes BS EN 13399:2010. BS EN 13399:2017 includes some technical changes with respect to BS EN 13399:2010. These include:
- Closing the filled tube with forceps is described
- Recovery of the sample by cutting off top and bottom section of the cooled aluminium tube with a knife is introduced
- Melting temperature for the top and bottom parts after the storage is given
- More test methods to indicate separation are included.
