17/07/2012 – 23/09/2013 Article 3, Regulation (EU) No 528/2012 Scope: Whole act

1. For the purposes of this Regulation, the following definitions shall apply:

‘nanomaterial’ means a natural or manufactured active substance or non-active substance containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1-100 nm.Fullerenes, graphene flakes and single-wall carbon nanotubes with one or more external dimensions below 1 nm shall be considered as nanomaterials.For the purposes of the definition of nanomaterial, ‘particle’, ‘agglomerate’ and ‘aggregate’ are defined as follows:—‘particle’ means a minute piece of matter with defined physical boundaries,—‘agglomerate’ means a collection of weakly bound particles or aggregates where the resulting external surface area is similar to the sum of the surface areas of the individual components,—‘aggregate’ means a particle comprising strongly bound or fused particles;
