Published By | Publication Date | Number of Pages |
BSI | 2024 | 42 |
This document specifies methods for sampling of soil improvers and growing media for subsequent determination of quality and quantity. It outlines the principles to be taken into consideration when taking the sample and ensuring an adequate quantity is available for testing. This document applies to material in solid form (including pre-shaped growing media) and liquid form. This document is intended to be used by manufacturers, buyers and enforcement agencies in verifying claims made for these materials. It is not intended that it should necessarily be used for the purpose of manufacturing control. The requirements of this document can differ from the national legal requirements for the declaration of the material concerned.
