Fertilizers. Sampling. Method of checking the performance of mechanical devices for sampling of solid fertilizer moving in bulk (British Standard)
This International Standard specifies a method of checking the performance of mechanical devices for sampling fertilizers moving in bulk by comparison of particle size distribution with that obtained by a reference method.
It is applicable to any form of mechanical sampling device installed at some point in a bulk-handling system, providing that either the fertilizer passes along a conveyor belt, before or after the device, or it is subsequently packed in bags in order that a reference collection can be made.
