Workplace exposure. Measurement of dustiness of bulk materials that contain or release respirable NOAA or other respirable particles - Rotating drum methodWhat is BS EN 171992 Rotating drum method for dustiness about? Airborne NOAA and other respirable particles released during handling and transportation of bulk materials is an important consideration for workers exposure. BS EN 171992 is the second part of the workplace exposure to respirable particles multi series. BS EN 171992 discusses the rotating drum method for measuring exposure. BS EN 171992 specifies the selection of instruments and devices

BS EN 50470‑1 also applies to operation indicator(s) and test output(s)

then for control purposes it can be sufficient to determine the water flow capacity at two loads and both gradients
