# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the manufacture of glass (notified under document C(2012) 865) (Text with EEA relevance) (2012/134/EU), Division: Conversion to reference oxygen concentration

Extent: E+W+S+N.I.

The formula for calculating the emissions concentration at a reference oxygen level (see Table 1) is shown below.
E R = 21 – O R 21 – O M × E M
Where:
ER (mg/Nm3) emissions concentration corrected to the reference oxygen level OR
OR (vol %) reference oxygen level
EM (mg/Nm3) emissions concentration referred to the measured oxygen level OM
OM (vol %) measured oxygen level.
