This International Standard specifies a method suitable for the reduction of a sample of a solid fertilizer to a smaller quantity such as may be used for analysis or for further reduction after suitable comminution.
By choosing suitable equipment, the method is applicable to the reduction of a sample of any mass above a minimum defined by the size and number of particles. The method can be applied to the division of samples into a number of equally representative sub-samples.
Other reduction devices and methods are described in Annex A but they are not as accurate as the recommended procedure.
This International Standard does not include information on the methods of obtaining the original sample.
