Water quality. Determination of dioxin-like polychlorinated Biphenyls. Method using gas-chromatography/mass spectrometry1 Scope This International Standard specifies a method for the determination of dioxin like tetra to hepta chlorinated biphenyls (PCBs) in waters and wastewaters (containing less than 1 % suspended solids) using high resolution gas chromatography high resolution mass spectrometry (HRGC HRMS). The method is optimized for dioxin like PCBs, but can include other co planar compounds such as polychlorinated dioxins and furans (PCDDs PCDFs) and

and testing of bicycles and sub-assemblies intended for off-road
