BS EN ISO 11465:2025

This standard BS EN ISO 11465:2025 Sludge and solid environmental matrices. Determination of dry residue or water content and calculation of the dry matter fraction on a mass basis is classified in these ICS categories:

• 13.080.20 Physical properties of soils

This document specifies methods for the calculation of the dry matter fraction of sludge, sludge products, treated biowaste, soil and waste for which the results of performed analysis are calculated to the dry matter basis. Depending on the nature and origin of the sample, the calculation is based on a determination of the dry residue (method A) or a determination of the water content (methods A and B). It applies to samples containing more than 1 % (mass fraction) of dry residue or more than 1 % (mass fraction) of water. Method A applies to sludge, sludge products, treated biowaste, soil and solid waste. Method B applies to liquid waste and to samples which are suspected or known to contain volatiles except for water.
