What is BS EN 12372 - Flexural strength of natural stone under concentrated load about?
BS EN 12372 is a European Standard that covers natural stone testing methods used for both internal and external surfaces of constructions. The main aim of BS EN 12372 is to offer manufacturers the best industry practices for demonstrating the effectiveness of natural stones for structures, not only for enhancing aesthetics but also for thermal insulation and protection against extreme weather conditions.
BS EN 12372 specifies a test method for the determination of flexural strength under a concentrated load for natural stone. Both an identification and a technological product testing procedure are included.
Who is BS EN 12372 - Flexural strength of natural stone under concentrated load for?
BS EN 12372 on the flexural strength of natural stone under concentrated load is useful for:
- Contractors
- Civil engineers
- Builders and architects
- Interior designers
- Stone specialists
- Geoscientists
Why should you use BS EN 12372 - Flexural strength of natural stone under concentrated load?
The flexural strength test under concentrated load is applied to assess the mechanical resistance of stone and it is well correlated with the petrographic properties of the stone. Flexural testing is used to determine the flex or bending properties of a material.
The principle of the flexural strength test method as mentioned in BS EN 12372 is to place a test specimen on two rollers and progressively load the specimen in the middle. The breaking load is measured, and the flexural strength is calculated.
In this regard, BS EN 12372 provides the apparatus requirements, test sampling and preparation as well as the test procedure to evaluate the flexural strength of natural stone.
As a result, complying with BS EN 12372 can help demonstrate the performance and durability of natural stones, thus determining whether or not they are fit for purpose in a specific environment.
