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 10058-1 was prepared by Technical Committee ISO/TC 33, Refractories.
This first edition of ISO 10058-1, together with ISO 10058-2 and ISO 10058-3, cancels and replaces
ISO 10058:1992 which has been technically revised to include the increasing use of flame atomic absorption
spectrophotometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) methods
as well some improvements in the wet chemical analyses procedures developed in Japan.
ISO 10058 consists of the following parts, under the general title Chemical analysis of magnesite and dolomite
refractory products (alternative to the X-ray fluorescence method):
⎯ Part 1: Apparatus, reagents, dissolution and determination of gravimetric silica
⎯ Part 2: Wet chemical analysis
⎯ Part 3: Flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma atomic
emission spectrometry (ICP-AES)
