What is BS EN 16457– Characterization of waste about?  
BS EN 16457 specifies requirements for a waste testing programme regarding mainly objectives, planning and report with the intent to ensure reliable and comparable results when using the reference methods that have been developed and/or adopted by CEN/TC 292.
The planning and report aspects of BS EN 16457 are applicable to any waste testing programme dedicated to the determination of one or several parameters.
They are also applicable to all testing steps for each parameter from sampling up to reporting whether these steps are taking place in the field (e.g. sampling) or in the laboratory (e.g. analysis-quantification).
BS EN 16457 does not address aspects of safety for activities in the field and inside laboratory.
NOTE The term planning a testing programme is used here with the general meaning of organizing a testing programme and being in accordance with the terms testing plan, sampling plan, laboratory plan used in the present European Standard.
Who is BS EN 16457– Characterization of waste for? 
BS EN 16457 on water quality is relevant to: 
- Chemical Engineer 
- Researchers and scientists 
- Microbiologists 
- Any entity responsible for disposing waste  
Why should you use BS EN 16457– Characterization of waste? 
BS EN 16457 is widely used by waste testing parties such as plant operators, testing institutes, accrediting bodies, as well as industries and regulators to address waste testing in their contracts.
BS EN 16457 provides requirements on the programme, objective, plan and report for the execution of a waste testing programme.
BS EN 16457 helps in determining different parameters in a waste sample and for each parameter different testing steps of a different nature need to be coordinated and performed.
BS EN 16457 benefits occupational biologists and researchers in preparing framework for the preparation and application of testing programmes from waste materials. 
You can determine different parameters and behaviour of waste from granular waste by applying BS EN 16457, which can lead to better decomposition of waste and help protect the environment.
