Particle size standards

Quote

(NIST) traceable particle size standards enable laboratories to validate or calibrate their particle sizing instruments or methods in order to comply with ISO, GMP, GLP and other international standards. They are traceable to certified reference materials from international standard organisations through an unbroken chain of measurement leading back to the standard meter.
