Soil quality - Screening soils for selected elements by energy-dispersive X-ray fluorescence spectrometry using a handheld or portable instrument (ISO/DIS 13196:2025)
ISO 13196:2013 specifies the procedure for screening soils and soil-like materials for selected elements when handheld or portable energy-dispersive XRF spectrometers are used. This quick method is assumed to be applied on-site to obtain qualitative or semiquantitative data that assists decisions on further sampling strategy for assessing soil quality. The higher the efforts for pretreatment used on soil samples, the better the analytical results can be expected.
ISO 13196:2013 does not explicitly specify elements for which it is applicable, since the applicability depends on the performance of the apparatus and the objective of the screening. The elements which can be determined are limited by the performance of the instruments used, the concentration of the element present in the soil, and the requirements of the investigation (e.g. guideline value).
For Hg, Cd, Co, Mo, V and Sb, a majority of instruments are not sensitive enough to reach sufficiently low limits of quantification (LOQ) to meet the requirements (limit or threshold values) set in the ordinances of different countries. In this case, other methods need to be employed to measure these low concentrations. Usually, wet chemical methods are used, based on aqua regia extracts, in combination with optical or mass spectrometric (MS) methods like atomic absorption spectrometry (AAS), inductively coupled plasma/optical emission spectrometry (ICP/OES) or ICP/MS.

Qualité du sol - Diagnostic rapide d’une sélection d’éléments dans les sols à l’aide d’un spectromètre de fluorescence X à dispersion d’énergie de type mobile ou pistolet (ISO/DIS 13196:2025)
L'ISO 13196:2013 spécifie la procédure d'analyse rapide d'une sélection d'éléments dans les sols et matériaux similaires lorsque l'on utilise des spectromètres XRF à dispersion d'énergie portables ou portatifs. Cette méthode rapide est supposée être appliquée sur site pour obtenir des données qualitatives ou semi-quantitatives qui aident notamment à décider de la stratégie d'échantillonnage plus poussée pour évaluer la qualité du sol. Plus les efforts de traitement préalable des échantillons de sol sont importants plus on peut s'attendre à des résultats d'analyse de qualité.
L'ISO 13196:2013 ne spécifie pas de façon explicite les éléments pour lesquels elle est applicable dans la mesure où ses possibilités d'application dépendent des performances de l'appareil, des caractéristiques du sol et des objectifs du diagnostic. Les éléments qui peuvent être déterminés sont limités par la performance des instruments utilisés, la concentration de l'élément présent dans le sol, et les exigences de l'investigation (par exemple la valeur de référence).
Pour Hg, Cd, Co, Mo, V et Sb, la majorité des instruments n'est pas assez sensible pour atteindre des limites de quantification assez basses (LOQ) pour satisfaire les exigences (valeurs limites ou seuils) mises en place par décret dans différents pays. Dans ce cas, d'autres méthodes doivent être utilisées pour mesurer ces basses concentrations. En règle générale, des méthodes chimiques par voie humide sont utilisées, fondées sur des extraits d'eau régale, en combinaison avec des méthodes de spectrométrie de masse ou optiques telles que AAS, ICP-OES ou ICP-MS.

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 www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical
and physical characterization.
This second edition cancels and replaces the first edition (ISO 13196:2013), which has been technically
revised, not touching the principle and procedure designated in the first version.
The main changes are as follows:
— the details of measurement options have been made clearer;
— suitable materials for the equipment for sampling and sample preparation are indicated;
— more information is provided for users of the International standard on requirements for:
— sieve;
— sample cup;
— basic operation of XRF spectrometers;
— safety instructions;
— sample preparation.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
