DEFRA tests for Great Britain
In Great Britain because of the DEFRA (Department for Environment, Food & Rural Affairs) there have been established smoke control areas. In order to be allowed to operate there solid fuel fireplaces, separate emission requirements have been established with reference to solids (particles) in the flue gas. The test methods are listed in the application pack ”Appliance Exemption from section 21 of the Clean Air Act 1993“. The tests in our body will be acknowledged by the Ricardo-AEA´s smoke control team.
