Additional information

In October 2011 the EU commission published a recommendation (2011/696/EU) on the definition of nanomaterials.  Standardised and certified methodologies (which are essential for accurate material characterisation, comparison and categorisation) to accompany this recommendation are now in development.  From the results of analysis by the non-standardised methods currently available, it is conceivable that the substance subject to registration could be considered as falling within the boundaries of the nanomaterial definition.
