BS EN 1367-5 is a European standard for testing the thermal and weathering properties of aggregates. The main aim of the BS EN 1367 series is to ensure increased durability and service life of aggregates used for construction purposes.
BS EN 1367-5 is a fifth part of the multi-series that specifies methods for the determination of resistance to thermal shock of aggregates, subject to heating and drying in the production of hot bituminous mixtures.
BS EN 1367-5 on aggregates resistance to thermal shock is useful for:
Thermal shock resistance refers to the aggregate’s ability to withstand extreme and rapid changes in temperature. Temperature fluctuations cause thermal stresses that result in damage to surfaces, and affects performance.
BS EN 1367-5 describes the reference method used for type testing and in case of a dispute. For the purpose of type testing and in case of a dispute only the reference method should be used. For other purposes, in particular factory production control, other methods may be used provided that an appropriate working relationship with the reference method has been established. BS EN 1367-5 provides guidance on apparatus, sampling, procedure, calculation, and expression of results for analyzing thermal shock failures.
If you are a manufacturer or supplier of aggregates, adhering to BS EN 1367-5 can assist you in demonstrating the performance and credibility of your product, ensuring that it is fit for purpose.
