Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established 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. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 21627 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 21627-3 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee
SC 12, Thermosetting materials.
This first edition cancels and replaces ISO 13651:1996, of which it constitues a technical revision.
ISO 21627 consists of the following parts, under the general title Plastics — Epoxy resins — Determination of
chlorine content:
— Part 1: Inorganic chlorine
— Part 2: Easily saponifiable chlorine
— Part 3: Total chlorine
