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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

INTERNATIONAL STANDARD ISO 5189:2023(E)
Fine ceramics (advanced ceramics, advanced technical
ceramics) — Methods for chemical analysis of metal
impurities in silicon dioxide powders using inductively
coupled plasma-optical emission spectrometry
1 Scope
This document specifies methods for the chemical analysis of metal impurities present in silicon dioxide
powders used as a raw material for fine ceramics.
It stipulates the methods for the determination of metal impurity elements in silicon dioxide powders
that are decomposed by acid decomposition. The aluminium, cadmium, calcium, copper, iron, lead,
lithium, magnesium, manganese, nickel, potassium, sodium, titanium, zinc and zirconium contents in
the test solution are determined by inductively coupled plasma-optical emission spectrometry (ICP-
OES).
