BS EN 60512-25-9 defines a test method to assess the near-end alien crosstalk (ANEXT) and the far-end alien crosstalk (AFEXT) between connectors in close proximity when mounted in their mounting systems

Essential oils. Analysis by gas chromatography on chiral capillary columns. General method Ingestion-build-54371 usually expressed in mg/m21 Scope This International Standard specifies a general method for the analysis of essential oils by gas chromatography on capillary chiral columns, for the purpose of determining the specific enantiomeric excess or distribution of the chiral compounds contained in the essential oils.
