Determining the dustiness of powders - comparison measurements with one of the reference test methods according to EN 15051

The dustiness of powders can be determined in a variety of ways. Two methods and the equipment they require are described as "reference test methods" in the European standard EN 15051 "Workplace atmosphere - Measuring the dustiness of bulk goods". Comparison measurements of dusting behaviour were performed on twelve powder substances using one of the above-named reference test methods and another method not named in the standard. According to DIN EN 15051 correlation functions were derived from the measurement results in order to enable comparison of the results of the two methods. The quality criteria for comparison that were named in the standard were exceeded in the present tests to such an extent that an equivalency of the two test methods is not given according to the standard.
