BS EN ISO 11771:2010 Air quality — Determination of time-averaged mass emissions and emission factors — General approach (ISO 11771:2010)

BS EN ISO 11771 is an International Standard which describes the measurement procedures necessary to determine the mass emission of substances from stationary sources.

Empirically generated data are necessary to determine the uncertainty that can be associated with a stated result and to enable the verification of emission measurement reports.

BS EN ISO 11771 also describes the measurement procedures necessary to determine emission factors. An emission factor is a value that relates the quantity of a pollutant released with an activity associated with the release of that pollutant. Emission factors are useful when the operational conditions and time period for which they are representative is known.

Emission factors are used to calculate and report mass emissions. These mass emissions can be used for:

  • Emission trading;
  • Compiling polluting release and transfer registers;
  • Air quality modelling;
  • Air quality management;
  • Compliance with national emission limits.
  • Developing site-specific emission estimates;
  • Developing control strategies;
  • Risk assessments;
  • Deciding appropriate permit limits.
