Natural gas - Determination of water by the Karl Fischer method - Part 2: Volumetric procedure (ISO 10101-2:2022)
This document specifies a volumetric procedure for the determination of water content in natural gas. Volumes are expressed in cubic metres at a temperature of 273,15 K (0 °C) and a pressure of 101,325 kPa (1 atm). It applies to water concentrations between 5 mg/m3 and 5 000 mg/m3.
Erdgas - Bestimmung des Wassergehaltes nach Karl Fischer - Teil 2: Volumetrisches Verfahren (ISO 10101-2:2022)
Dieses Dokument legt ein volumetrisches Verfahren zur Bestimmung des Wassergehaltes von Erdgas fest. Die Volumina werden in Kubikmetern angegeben und beziehen sich auf eine Temperatur von 273,15 K (0 °C) und einen Druck von 101,325 kPa (1 atm). Dieses Verfahren gilt für Wasseranteile zwischen 5 mg/m3 und 5 000 mg/m3.
WARNUNG — Falls die Apparatur in einem explosionsgefährdeten Bereich aufgestellt wird, sollten die örtlichen Sicherheitsbestimmungen beachtet werden.

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.

in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 10101-2:1993), which has been technically
revised.
The main changes are as follows:
— Clause 2 and Bibliography were revised;
— New fixed structure numbering inserted;

Introduction
Water vapour may be present in natural gas due to, for example, natural occurrence in the well
production stream, the storage of gas in underground reservoirs, transmission or distribution through
mains containing moisture or other reasons.
