BS EN 14227-4:2013 is a standard that specifies the requirements for siliceous and calcareous fly ash used in hydraulically bound mixtures for various applications, such as roads and airfields. The standard focuses on fly ash that is produced through the combustion of pulverised coal or lignite in energy generating plants.

The purpose of this standard is to provide guidelines for the classification and characterization of fly ash, ensuring its suitability for use in hydraulically bound mixtures. It establishes requirements for various physical and chemical properties of fly ash, including composition, fineness, loss on ignition, and sulfate content, among others. The standard also specifies testing methods for the determination of these properties.
