Water quality. Determination of anionic surfactants by measurement of the methylene blue index MBAS Ingestion-build-183511 test methods and conditions ofWhat is BS EN 903 Determination of anionic surfactants about? BS EN 903 helps in determining the anionic surfactants by measurement of the methylene blue index MBAS. BS EN 903 applies to drink water, surface water as well as wastewater, e. g. for the determination of the primary degradation of surfactants being under investigation in test systems containing natural or synthetic wastewater. BS EN 903 applies to both laboratory scaled and technical
