BS EN 17085:2019 pdf free.Paper and board – Sampling procedures for paper and board for recycling.
BS EN 17085 1 Scope This document specifies a method of obtaining representative samples from a lot of paper and board for recycling for testing to determine whether or not its composition and quality comply with the requirements of EN 643 and/or other specifications. This document also specifies the positioning of probes, when in situ measurements are performed. It defines the sampling procedures which apply when sampling is carried out to resolve compliance issues and commercial disputes between buyer and seller relating to a lot of paper and board for recycling, at any point in the value chain, where those procedures are not defined in the contract between buyer and seller. This document is not specifically intended for routine monitoring of processes or quality, but the procedures described may be used to form the basis of an agreement between supplier and buyer. This document is not applicable if the material is not intended for recycling. The method is not intended for determining the variability within a lot, however, the general sampling principles can be applied. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

EN 643, Paper and board一European list of standard grades of paper and board for recycling.As a precursor to the analysis of loose material, a representative macro-sample shall be extracted from the lot. The material shall be randomized to ensure representative sampling. An example approach would be to tip (discharge) the load onto the floor and mix it with a loading shovel, or similar equipment. This can be achieved by separating a proportion of the material (approximately four times greater than the required sample size) and lifting it up and dropping it back on the floor at least twice using a loading shovel. This will help redistribute unwanted materials that have settled to the bottom of the load. A push wall will help with the mixing process. BS EN 17085 pdf download.
