New Quality Audit Standards
Dec 20 2005
The new batch of standards was commissioned from independent specialist company Whitehouse Scientific (Chester, UK) who designed and produced a new high-capacity spinning riffler specifically for the task. Starting with a master batch of 1000kg of glass beads with a size distribution from 13 to 130 microns, Whitehouse successfully split this bulk material through various riffling stages, into final lots of 2.5g and 0.25g single shot bottles.
The standard deviation obtained from a comprehensive series of bottle-to-bottle particle size measurements was 0.2 to 0.3%. This means that the particle size distribution obtained from one bottle to another is equal to that obtained from repeat measurements of a single well-dispersed sample.
