EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 993-9 testing. This European Standard specifies a method for determining yield in compression of dense and insulating shaped refractory products, which is the deformation of a refractory product subjected to a constant load under isothermal conditions.
A test piece is subjected to a constant load and then heated to a certain temperature under certain conditions. The deformation of the test piece is recorded and the percent change evaluated as a function of time.
EN 993-9 is a standard that specifies the method for determining creep in the compression of densely shaped refractory products. Creep is a measure of the deformation of a material over time under a constant load and is an important consideration for refractory products used in high temperature applications.
The test method involves subjecting a test sample of refractory product to a constant compressive load at a specified temperature for a specified period of time. The deformation of the specimen is measured at regular intervals during testing and this data is used to calculate compression creep.
The standard provides detailed instructions on the preparation of test specimens, test equipment, and test procedure. The temperature and load range covered by the standard are determined according to the intended use of the refractory product.
This standard is used by manufacturers of densely shaped refractory products to ensure that their products meet the required creep resistance specifications. It is also used by testing laboratories to provide independent verification of product creep resistance properties.
Creep in compression testing is important for refractory products used in high temperature applications such as furnaces and kilns because it demonstrates the product's ability to withstand prolonged loading at high temperatures without significant deformation. This information is critical in ensuring the safety and efficiency of these high temperature processes.
