What is BS EN 17199-5 - vortex shaker method for NOAA about ?
Airborne NOAA and other respirable particles released during handling and transportation of bulk materials is an important consideration for workers’ exposure.  BS EN 17199 discusses workplace exposure to respirable particles. 
BS EN 171995 is the fourth part of the multi-series on workplace exposure, and describes the vortex shaker method for measuring and characterizing the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions.
BS EN 171995 is applicable to the testing of a wide range of bulk materials including nanomaterials in powder form.
Note: BS EN 171995 is not applicable to millimetre-sized granules or pellets containing nano-objects in either unbound, bound uncoated and coated forms.

Why should you use BS EN 17199-5 - vortex shaker method for NOAA ?
BS EN 17199-5 specifies the selection of instruments and devices and the procedures for calculating and presenting the results of the dustiness testing using the vortex shaker method for NOAA. BS EN 17199-5 also gives guidelines on the evaluation and reporting of the data.
- The methodology described in BS EN 17199-5 enables:
- The measurement of the respirable dustiness mass fraction
- The measurement of the number-based dustiness index of respirable particles in the particle size range from about 10 nm to about 1 µm
- The measurement of the number-based emission rate of respirable particles in the particle size range from about 10 nm to about 1 µm
- The measurement of the number-based particle size distribution of the released respirable aerosol in the particle size range from about 10 nm to 10 µm
- The collection of released airborne particles in the respirable fraction for subsequent observations and analysis by electron microscopy
BS EN 17199-5 contributes towards the safety of those handling materials containing NOAA by specifying the dustiness measurements and characterization of those materials. BS EN 17199-5 enables businesses that use bulk materials containing NOAA to assess the controls and precautions required for handling and working with the materials. BS EN 17199-5 lets manufacturers that use NOAA materials, assess the effects of pre-treatments.
BS EN 17199-5 is useful for addressing the dustiness released by bulk materials (including nanomaterials) during agitation. BS EN 17199-5 is applicable to the testing of a wide range of bulk materials, including nanomaterials in powder form. BS EN 17199-5 specifies the design and operation of the vortex shaker test method, which helps differentiate between useful and harmful particles.
