BS EN 14147 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 14147 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 14147 specifies a method to assess the resistance of natural stones to ageing by salt mist.
BS EN 14147 on resistance of natural stones to ageing by salt mist is useful for:
Salt mist testing is very important for assessing the suitability of products intended for outdoor use or for use in cold or wet environments. It is a standardized test method used to check the corrosion resistance of coated samples. The test produces a corrosive attack on the coated samples in order to predict the coating's suitability for use as a protective finish.
In this regard, BS EN 14147 provides the requirements of apparatus and includes the preparation, sampling, dimensioning, washing, drying of the test specimen and test procedures for testing natural stones.
As a result, complying with BS EN 14066 can help demonstrate the performance and durability of natural stones, thus determining whether or not they are fit for purpose in a specific environment.
