What is BS EN 13471 - Thermal expansion coefficient of thermal insulating materials about?
The quality and performance of thermal insulation products are critical when it comes to achieving operational energy efficiency in buildings, as they can effectively minimize heat loss and heat gain, as per the external weather conditions.
BS EN 13471 is a European Standard that discusses thermal insulation products for buildings equipment and industrial installations. The main aim of BS EN 13471 is to provide manufacturers with best industry practices to demonstrate the performance of thermal insulation products, such that they are fit for its intended use.
BS EN 13471 specifies the equipment and procedures for determining the coefficient of linear
thermal expansion. The standard is applicable to thermal insulating products within the temperature range - 196 °C to 850 °C, subject to the possible temperature limitation of the test specimens.
Note: BS EN 13471 shall not be used for products that during the test experience dimensional changes due to the loss of hydration water or which undergo other phase changes.
Who is BS EN 13471 - Thermal expansion coefficient of thermal insulating materials for?
BS EN 13471 on thermal expansion coefficient of thermal insulating materials is useful for:
- Thermal and sound insulating material manufacturers
- Contractors
- Civil engineers
- Consultancies for thermal insulation
- Specifiers and installers
- Quality control and testing personnel
Why should you use BS EN 13471 - Thermal expansion coefficient of thermal insulating materials?
The coefficient of linear thermal expansion is a material property that is indicative of the extent to which a material expands upon heating. Thermal expansion is vital during construction and design to prevent major structural damage.
The changes in a product’s linear dimensions, as its temperature is changed, are measured and
characterised. It shall be done in a continuous way when the full curve over a temperature range is needed or only at two specified temperatures if only a mean coefficient of linear thermal expansion between these temperatures is needed.
In this regard, BS EN 13471 specifies the apparatus requirement, preparation of test specimen and test procedure to determine the coefficient of linear thermal expansion.
Thus, if you are a manufacturer of thermal insulating products for thermal insulation, complying with BS EN 13471 can help demonstrate the performance and credibility of your product, ensuring that they are fit for the purpose.
