This protocol was developed and subsequently tested in 2012-2015 by Nordic test and research institutes, with Danish Technological Institute (DTI) as project manager. This protocol describes a potential standardized procedure for measurements of BC (Black Carbon) in terms of both EC (Elemental Carbon) and OC (Organic Carbon) from residential wood burning stoves. Such a standardized test can then be used for voluntary eco-labeling of wood stoves, and by manufacturers interested in testing and developing extremely low-emission, low-black carbon, “climate-friendly” stoves. This testing protocol is part of a project supported by the Nordic Council of Ministers and the Climate and Clean Air Coalition (CCAC), and implemented by the International Cryosphere Climate Initiative (ICCI).
