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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 21627-3 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 12,
Thermosetting materials.
This second edition cancels and replaces the first edition (ISO 21627-3:2002), which has been technically
revised.
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

Introduction
In producing epoxy resins based on epichlorohydrin, impurities containing chlorine may be formed. These are
shown below. Since these impurities could impair the final properties of the cured resins, it is necessary to
control their formation. Their chemical activities differ significantly
