Full title and description
ISO 10101-1:2022 — Natural gas — Determination of water by the Karl Fischer method — Part 1: General requirements. This part gives the general requirements that apply to the determination of water in natural gas using Karl Fischer techniques and references the specific procedures given in Parts 2 (titration) and 3 (coulometry).
Abstract
This document specifies general requirements for measuring the water content of natural gas by the Karl Fischer method, including definitions, principle, sampling and handling considerations, general test conditions and references to the two specific measurement procedures (titration and coulometric). It is intended to ensure reproducible, traceable results when Parts 2 and 3 are applied.

Scope
Specifies general requirements applicable to the determination of water in natural gas by the Karl Fischer method. It covers the principle of the method, requirements for sampling and sample handling that impact water determination, general test conditions and references the two detailed procedures: Part 2 (titrimetric Karl Fischer procedure) and Part 3 (coulometric Karl Fischer procedure). The part is intended to be used together with ISO 10101-2 and ISO 10101-3 to produce validated, comparable results.
Key topics and requirements
- Definition of the scope and terminology related to water determination in natural gas.
- Principles of the Karl Fischer reaction and overview of titrimetric and coulometric approaches.
- General requirements for sampling, sample containers and handling to avoid moisture ingress or loss.
- Reference to calibration, reagents and method validation as implemented in Parts 2 and 3.
- Guidance on test conditions, repeatability and considerations for uncertainty and traceability.
Typical use and users
Used by analytical laboratories, gas transmission and distribution companies, gas producers, custody transfer and metrology laboratories, and regulators concerned with quality control of natural gas. It supports laboratory test method selection and quality assurance for water content measurements where Karl Fischer techniques are appropriate.
Related standards
ISO 10101-2 (titration procedure) and ISO 10101-3 (coulometric procedure) — the three parts together form the ISO 10101 series for water determination in natural gas. This 2022 edition of Part 1 replaces the earlier ISO 10101-1:1993. National adoptions (EN, DIN, BS, etc.) exist and may include national forewords or additional editorial matter.
