BS EN 1159 is a European Standard that discusses thermophysical properties of ceramic composites.
BS EN 1159-2 is the second part of the series that describes the laser flash method for the determination of thermal diffusivity of ceramic matrix composites with continuous fibre reinforcement.
The experimental conditions are such that the material behaves in a homogeneous manner for each of its axes of anisotropy and that the heat transfer occurs only by thermal conduction.
The method mentioned in BS EN 1159-2 is applicable to materials that are physically and chemically stable during the measurement and covers the range of temperature between 100 K and 2 800 K. BS EN 1159-2 is suitable for the measurement of thermal diffusivity values.
BS EN 1159-2 on thermal diffusivity of ceramic composites is useful for:
Advanced technical ceramics have a multitude of valuable properties that make them useful in various industries for several important applications. Their thermophysical properties such as thermal diffusivity are an important consideration when it comes to determining whether the materials play a positive role in the performance of the end-application.
Determining the thermal diffusivity of ceramics is vital as it tells us how quickly heat is transferred to the cooler end.
BS EN 1159-2 provides best industry guidance on determining thermal diffusivity of ceramic composites to demonstrate whether your materials are capable of withstanding unsteady-state heat transfer situations. This can ultimately indicate if your materials exhibit adequate thermal conductivity and heat capacity as required for the optimal performance of the end-application.
Thus, adopting test methods in compliance with BS EN 1159-2 can be beneficial for quality control purposes and to ensure your materials are fit for purpose.
