This document is applicable to the sampling of solid fertilizers and liming materials that have a uniform composition and have no tendency to segregate.
NOTE 1 The term product is used throughout the body of this document and is understood to include fertilizers, liming materials and inhibitors unless otherwise indicated.
NOTE 2 Manufacturers, importers and sellers can choose to use this method to obtain samples of other products or blends as well as long as both parties to a transaction agree. The build-up of a static heap often leads to granulometric segregation, which makes the collection of a truly representative sample of many products and blends unlikely.
NOTE 3 It is the responsibility of manufacturers, importers and sellers, however, to ensure they supply a product that complies with its label declaration at the moment of delivery and fulfils the expectations of the end user at the moment of application.
NOTE 4 A method of obtaining a screening sample from a static heap can be found in Annex B.
