What is BS EN 14793 - Stationary source emissions about ?
BS EN 14793 specifies a procedure to demonstrate the equivalence of an alternative method (AM) with the reference method (RM) or the standard reference method (SRM), both implemented to determine the same measurand.
A reference method has been defined and validated in BS EN 14793 and only considers the case of linear quantitative methods.
BS EN 14793 applies to manual and automated methods and has been drawn up for laboratories working in air quality measurements and consequently, an example taken from this sector are presented in Annex A.
Who is BS EN 14793 - Stationary source emissions for ?
BS EN 14793 on stationary waste emissions is relevant to:
- Product Engineers
- Chemical Engineers
- Manufacturers and industries using furnaces and gas towers
- Researchers and scientists
Why should you use BS EN 14793 - Stationary source emissions ?
BS EN 14793 provides the statistical tools and different criteria to evaluate the alternative method. This does not release the body performing the equivalence testing from bearing technical and analytical judgement on the evaluation of the different criteria.
BS EN 14793 helps in determining the performance characteristics of the alternative method and calculation of the expanded uncertainty, where appropriate. It also allows checking of compliance with the maximum expanded uncertainty allowed for the reference method.
BS EN 14793 checks for repeatability and lack of systematic deviation of the alternative method in the field or on a recognized test bench in comparison with the reference method for the type of matrix defined in the field of equivalence.
Overall, BS EN 14793 specifies the demonstration of equivalence of an alternative method with the reference method, which will provide more methods for stationary source emissions based on sampling flue gases released to the atmosphere from ducts.
