Thermal insulation products are used extensively in the building and construction sector. This European standard dictates the procedure and equipment required to find the flexural properties of insulating materials. These properties are important for discovering the ability of the material to withstand bending stresses, which can occur during transportation or in their final application. The standard allows for the testing of both full size products (Method A) and specialized test specimens (Method B). The required results are maximum bending force, stress, and deflection.
