BS EN 14243 series discusses materials obtained from the end-of-life tyres. BS EN 14243-1 is the first part of a series of documents and an international standard for materials obtained from end-of-life tyres. BS EN 14243-1 specifies the general definitions of materials that help in categorizing the materials obtained from the end-of-life tyres by defining them according to their dimensions.
BS EN 14243-1 provides general definitions for sample collection and preparation of a representative sample based on a sampling plan for the purpose of determining dimensions and impurities.
BS EN 14243-1 on materials obtained from end-of-life tyres is useful for:
When a tyre is no longer safe or efficient to reuse, even if re-treaded, it is referred to as an "end-of-life tyre", that is waste and must be collected and recovered in specific factories, as well as for material recycling.
BS EN 14243-1 is useful in determining the characteristics of end-of-life tyres which helps in identifying and differentiating the items of a given population. The extraction of material in a single operation can be done by using a sampling device. The probabilistic sampling mentioned in BS EN 14243-1 helps in conducting the sample with the help of statistical principles of sampling.
The sieving is helpful in characterizing the materials which can be distributed in particle size by using the dimensions specified in BS EN 14243-1. The size reduction of end-of-life tyres done at different stages of the treatment processes is differentiated according to their dimensions.
BS EN 14243-1 classifies the sample collection and helps in preparing the sampling plan which helps in determining the dimensions and impurities of the material used in end-of-life tyres.
