ISO 13165-2:2014 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by emanometry. The method specified is suitable for the determination of the soluble, suspended, and total 226Ra activity concentration in all types of water with soluble 226Ra activity concentrations greater than 0,02 Bq l-1. In water containing high activity concentrations of 228Th, interference from 220Rn decay products can lead to overestimation of measured levels.

This document provides a framework for the detailed assessment and monitoring of dynamic soil properties related to soil function with concomitant recording of in-situ static soil properties, landscape, land use and soil management practices that influence function at the time the data were collected. It is applicable to the assessment of soil quality in agricultural landscapes, contaminated sites and natural soil ecosystems at plot, field and landscape spatial scales. It can also be applied in the development of dynamic properties databases to enhance existing soil survey databases for estimation of carbon stocks in soils, sustainable agriculture, landscape management etc. Although the soil quality description framework has been developed to describe surface soils, the same principles can be applied to adapt the framework to describe subsurface soil horizons.

This document specifies a method for quantitative determination of the concentration of selected alcohols with low boiling point in liquid waste and pasty waste by gas chromatography with flame ionization detection after static headspace extraction.Under the conditions specified in this document, a limit of application of 20 mg/kg, expressed on dry matter for pasty waste and expressed on raw waste for liquid waste, can be achieved.

This document specifies the principles of inductively coupled plasma mass spectrometry (ICP-MS) and provides general directions for the use of this technique for determining elements in water, digests of sludges and sediments (for example, digests of water as described in ISO 15587-1 or ISO 15587-2). Generally, the measurement is carried out in water, but gases, vapours or fine particulate matter can be introduced too. This document applies to the use of ICP-MS for aqueous solution analysis. The ultimate determination of the elements is described in a separate International Standard for each series of elements and matrix. The individual parts of this document refer the reader to these guidelines for the basic principles of the method and for configuration of the instrument.
