This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. It provides guidance on the features and processes to be taken into account when characterizing and assessing the hydromorphology of rivers. It is based on methods developed, tested, and compared in Europe. Its main aim is to improve the comparability of hydromorphological assessment methods, data processing and interpretation. Although it has particular importance for the WFD by providing guidance on assessing hydromorphological quality, it has considerably wider scope for other applications. In addition, while recognizing the important influence of hydromorphology on plant and animal ecology, no attempt is made to provide guidance in this area, but where the biota have an important influence on hydromorphology these influences are included.

NOTE          A case study illustrating the application of this standard is given in Gurnell and Grabowski[1].

This document gives criteria for mass spectrometric identification of target compounds in water samples and may be applied to environmental samples in general. This document shall be used in conjunction with a standard developed for the determination of the specific compounds, for example, ISO 17943[3] for volatile organic substances or ISO 16693[1] for determination of organochlorine pesticide (OCP). If the standard method for analysing specific compounds includes criteria for identification, those criteria shall be followed.

This document specifies the critical points to consider while developing an in‑house mass spectrometry‑based method for quantitative analysis of multi‑group organic substances in the scope of physical‑chemical analysis of water.

ISO/TS 13530 provides guidance on the initial characterization of the measurement performances. This document supplements ISO/TS 13530 by providing details on the following points:

—    selection of the characterization-test matrix;

—    internal standards and internal standard recoveries;

—    analyte recovery;

—    checking that performance levels do not degrade over time.

Chromatographic separation and identification of analytes are described in ISO/DIS 21253‑1.

The estimation of measurement uncertainties is integral to the characterization of any quantitative method of analysis, but the process is not described here, as ISO 11352 applies. Similarly, the calibration protocols are not described here but set out in the ISO 8466‑ series of standards.

This document is not intended as a substitute for the currently applicable analytical standards dedicated to organic compounds but as a resource bringing additional characterization elements.
