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 20565-3 was prepared by Technical Committee ISO/TC 33, Refractories, in collaboration with Technical
Committee CEN/TC 187, Refractory products and materials.
ISO 20565 consists of the following parts, under the general title Chemical analysis of chrome-bearing
refractory products and chrome-bearing raw materials (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 spectrometry (FAAS) and inductively coupled plasma atomic emission

1 Scope
This part of ISO 20565 specifies flame atomic absorption spectrometry (FAAS) and inductively coupled
plasma atomic emission spectrometry (ICP-AES) methods for the chemical analysis of chrome-bearing
refractory products and chrome-bearing raw materials.
It is applicable in the ranges of determination given in Table 1.
ISO 20565 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.

3 Instrumental methods using inductively coupled plasma emission spectrometry
(ICP-AES)
3.1 Determination of residual silica in stock solutions (S1) by ICP-AES
3.1.1 Principle
The residual silica remaining in solution in solutions (S1) is determined using ICP-AES.
3.1.2 Reagents
Prepare the following reagents in addition to any reagents described in ISO 20565-1:2008, Clause 5, that are
necessary.
3.1.2.1 Diluted silicon(IV) oxide standard solution, SiO 0,08 mg/ml.
Transfer 20 ml of the silicon(IV) oxide standard solution (SiO 1 mg/ml) into a 250 ml volumetric flask and
dilute to the mark with water.
3.1.2.2 Matrix solution 2.
Carry out the procedure given in ISO 20565-1:2008, 9.2.2.3, without the sample, but omit heating the fusion
mixture or anhydrous sodium carbonate. The equivalent solution to stock solution (S1) is referred to as matrix
solution 2.
3.1.2.3 Series 2 solution for calibration.
Transfer appropriate aliquot portions of diluted silicon(IV) oxide standard solution (0,08 mg/ml) precisely into
several 100 ml volumetric flasks in accordance with the composition of the samples. Add 10 ml each of matrix
solution 2 (3.1.2.2) and dilute to the mark with water.
In Table 2, a typical example of the preparation of solutions is shown. In accordance with th
