ISO/DIS 19658

Sludge recovery, recycling, treatment and disposal — Protocol for validating methods for physical properties of sludges

Scope

This international standard is intended to provide a protocol for the interlab validation of methods for the characterization of sludge/biosolids physical properties considered that in most cases fresh sludge samples cannot be circulated to several laboratories in different countries for validation purposes as uncontrolled variations of their characteristics would occur.
