What is BS EN 15863– Characterization of waste about?  
BS EN 15863 is applicable for determining the leaching behaviour of monolithic wastes under dynamic conditions. The test is performed under fixed experimental conditions in BS EN 15863.
NOTE 1 If, in order to comply with the requirements of regular shape, the test portion is prepared by cutting or coring, then new surfaces are exposed which can lead to change(s) in leaching properties. On the other hand if the test portion is prepared by moulding, the surface will be dependent to the type of mould and the conditions of storage. If the intention is to evaluate the behaviour of the material core, the specimen needs to be stored without any contact with air to avoid carbonation.
NOTE 2 For monolithic waste materials with a saturated hydraulic conductivity higher than 10−8 m/s water is likely to percolate through the monolith rather than flow around. In such cases relating the release to the geometric surface can lead to misinterpretation. A percolation test is more appropriate then (e.g. CEN/TS 14405).
This procedure may not be applicable to materials reacting with the leachant, leading for example to excessive gas emission or an excessive heat release.
Who is BS EN 15863– Characterization of waste for? 
BS EN 15863 on water quality is relevant to: 
- Chemical Engineer 
- Researchers and scientists 
- Microbiologists 
- Any entity responsible for disposing waste  
Why should you use BS EN 15863– Characterization of waste? 
Leaching is the loss of soluble substances and colloids from the top layers of soil through percolation. 
BS EN 15863 specifies a dynamic leaching test for monolithic waste materials, to determine key parameters to address the leaching behaviour of monolithic waste materials.
BS EN 15863 has been developed to determine the release of mainly inorganic constituents from wastes.
BS EN 15863 does not take into account the particular characteristics of organic constituents, nor the consequences of microbiological processes in organic degradable wastes.
BS EN 15863 specifies test methods for characterizing leaching behaviour of inorganic and non-volatile organic substances from granular waste materials under standardized conditions. 
BS EN 15863 benefits occupational biologists and researchers in understanding the leaching behaviour of inorganic and non-volatile organic substances from granular waste materials. 
You can determine the leaching behaviour of waste from granular waste by applying BS EN 15863, which can lead to better decomposition of waste and help protect the environment.
