Designing protection measures requires explosion characteristics to be determined, namely the maximum explosion pressure and the maximum rate of pressure rise. Safety characteristics of single-phase components (solid, liquid or gas) can be determined according to standards that were developed 40 years ago and are continuously improved. For hybrid mixtures containing a flammable gas and a combustible dust there has been an approach in the 80s but it has never been improved nor applied ever since (ISO 6184-3). A new approach by four German research facilities and the German Institute for standardization (DIN) with the aim of developing a new standard was launched in 2019. In 2022 the key findings led to a first international round robin test with eleven participating facilities from seven countries. The dust component was corn starch and methane was chosen as gas component. In order to strengthen the data foundation before finalizing and publishing the new standard, a second round robin test was initiated with hydrogen as gas component and lycopodium as dust. The paper will summarize the findings and their influence on the new standard.
