Price based on 7 pages Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards institutes (Iso member bodies). The work of developing Inter- national Standards is carried out through Iso technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with iso, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISo Council. International Standard ISO 6384 was developed by Technical Committee ISO/TC 91, Surface active agents, and was circulated to the member bodies in October 1979. It has been approved by the member bodies of the following countries : Australia Hungary Romania Austria India South Africa, Rep. of Belgium Italy Spain Chile Japan Switzerland Egypt, Arab Rep. of Korea, Rep.of USA France Netherlands USSR Germany, F.R. Poland No member body expressed disapproval of the document. This International Standard has also been approved by the International Union of Pure and Applied Chemistry (IUPAC).

This International Standard specifies methods of analysis for technical ethoxylated fatty amines. It covers the following General principle determinations : On separate test portions : Measurement of apparent pH in methanolic medium. measurement of the apparent pH in methanolic Determination of water content. medium; Determination of the distribution of primary, secondary determination of the water content; and tertiary amines contents. determination of the distribution of primary, secondary Determination of oxyethylene groups content. and tertiary amines contents; Determination of sulphated ash. determination of oxyethylene groups content; Determination of free polyethylene glycols content. determination of sulphated ash.
