This document specifies methods for the determination of a quantity of soil improvers and growing media in bulk and in packages. This method is designed with an appropriate precision level so that it can be used to validate any quantity determination made.
This document is applicable to material in any form, reconstituted if necessary, but not to plugs, blocks and slabs sold as such by dimension; for these, see EN 15761.
This document is not applicable for material with more than 10 % (V/V) of particles greater than 60 mm in size; for these, see EN 15238.
The requirements of this document might differ from the national legal requirements for the determination of the products concerned.
Material which has become excessively wet and which cannot be easily broken down into a flowable material will not be suitable for the determination of quantity and might not give a representative result. However, because of the diverse nature and bulk density of these materials, it is not possible to quantify what is ‘excessive’.
This document is intended to be used by manufacturers, buyers and enforcement agencies in verifying claims made for these products.
