Soil and waste - Determination of Chromium(VI) in solid material by alkaline digestion and ion chromatography with spectrometric detection (ISO/DIS 15192:2023)
This document specifies the determination of Cr(VI) in solid waste material and soil by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE In case of reducing or oxidising waste matrix no valid Cr(VI) content can be reported.

Le présent document spécifie le dosage du Cr(VI) dans les déchets solides et les sols par digestion alcaline et chromatographie ionique avec détection spectrophotométrique. Cette méthode peut être utilisée pour déterminer les fractions massiques de Cr(VI) dans les solides supérieures à 0,1 mg/kg.
NOTE Il n’est pas possible de consigner une teneur en Cr(VI) valable dans un rapport lorsque la matrice de déchets est réductrice ou oxydante.

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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee
SC 3, Chemical and physical characterization, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 444, Environmental Characterization, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 15192:2010), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— integration of the determination of the total chromium in the alkaline digestion solution;
— Addition of barium chromate as an alternative to lead chromate for the verification of the me
