Sieve Standards, Polydisperse Particle Standard
Standarder Particle Size Standards

The Polydisperse particle standards formally known as the BCR 'Mirror' standards were made both to assess the performance of the analytical laboratories and to augment a limited supply of the official standards. Although sub-divided, the BCR samples were never certified, which leaves these new polydisperse particle standards as the most comprehensively analysed set of spherical particle size reference standards available.


  • Calibration for any method of particle size analysis
  • Unambiguous primary methods used - microscopy, sieving, sedimentation and the Coulter method


Traceability through NIST, BCR and NPL standards.
