WCCAP is working for the BLUE ANGEL – the German ecolabel

The Blue Angel has been the ecolabel of the German federal government for more than 40 years. It is awarded to environmentally friendly products and services. No other label in the non-food sector covers such a wide range of products and services.
 
The aim of the environmental label is to provide private customers, large institutional consumers and public institutions with reliable guidance for environmentally conscious purchasing. If there is a specific demand for environmentally friendly products, it promotes ecological product innovations and reduces the burden on the environment. The Blue Angel stands for independent, transparent and ambitious labelling.
  
Since recently, the BLUE ANGEL is available for stoves. The aim of the ecolabel in this sector is to encourage innovation and promote new developments in the design of stoves for the improvement of air quality.
 
To be certified with the Blue Angel, the stoves are subjected to an expanded test process that reflects the real emissions from burning wood. On this basis, stricter limits for pollutant emissions including the mass of the particulate matter have been defined. Furthermore, the Blue Angel for stoves calls, for the first time, for the introduction of a particle count limit for wood-burning stoves in order to protect human health.
  
Several test centers are already equipped with the appropriate devices for testing the criteria (primarily the number of particles), but there are no comparative measurements between the individual centers in order to obtain an overview of the scatter of the results under comparable conditions yet. This is where the WCCAP comes in. Within a round robin test, the instruments of the test centers come to the WCCAP to determine their performance, to check them against each other and to bring them to the same measurement level. In a next step, these quality assured instruments were used to determine the particulate matter emissions simultaneously at the same exhaust stack. The results of these tests are then used to validate the new method.
