What is BS EN 15445 – RDM for industrial emissions about?  
BS EN 15445 specifies a Reverse Dispersion Modelling (RDM) method to qualify the fugitive emission rates of diffuse fine and coarse dust sources of industrial plants or areas. The application needs calculations using a dispersion model, and the definition of a sampling experimental set-up taking into account field data such as number, height and width of diffuse dust sources, sampling distances, and meteorological information.
The RDM method does not allow quantification in absolute figures of the dust emission rates because of an undetermined accuracy depending on various site conditions, but it is a tool which enables each industrial plant to identify its dust sources that emit the most, and then to implement actions reducing their importance by self-control and related improvement process as part of environmental management.
In this framework, the RDM method should not be used to control or verify any compliance with air quality threshold global values which might be contained in an operating permit, or to carry out a comparison between different plants belonging to the same industrial sector.
Who is BS EN 15445 - RDM for industrial emissions for? 
BS EN 15445 on ‘RDM for industrial emissions’ is relevant to any organization that releases emissions during production. EN 15445 is useful for: 
- The manufacturing industry
- The chemical industry
- Factory managers
- Quality control/testing personnel
- Regulatory bodies
- Environmental management divisions
- Environmental health authorities
- Health and safety bodies
Why should you use BS EN 15445 – RDM for industrial emissions?  
Exposure to diffuse fine and coarse dust sources from industrial emissions affects the health of personnel as well as others in the vicinity. Using RDM helps to assess these emissions.
BS EN 15445 guides you with aspects of the RDM technique such as:
- Measurement equipment
- Dispersion model
- Procedure
- Calculations
- Precision
