Full title and description

ISO 10101-2:1993 — Natural gas — Determination of water by the Karl Fischer method — Part 2: Titration procedure. This is the original ISO international standard that specifies a titrimetric (Karl Fischer) procedure for determining water content in natural gas; Russian-language (rus) PDF translations and national/adopted versions have been issued by various standards bodies and commercial resellers.

Abstract

The standard describes a method in which a measured volume of natural gas is passed through an absorbent solution; water in the gas is collected by the absorbent and subsequently determined by Karl Fischer titration. The procedure is intended for water concentrations in natural gas approximately between 5 mg/m3 and 5 000 mg/m3 and includes requirements for the sampling cell, absorbent solution, titration and calculation of results.

Scope

Specifies a titration procedure (Karl Fischer titrimetry) for the determination of water content in natural gas. The method covers the collection of water from a flowing gas stream into an absorbent, titration of the collected solution and the calculation of water concentration in the gas sample. It is intended for a practical concentration range from about 5 mg/m3 up to about 5 000 mg/m3 and is intended for laboratory and routine test applications in the natural-gas sector.

Key topics and requirements

• Principle: extraction of water from a measured gas volume into an absorbent followed by Karl Fischer titration.
• Design and requirements for the gas sampling/absorption cell to ensure efficient collection at process flow rates.
• Specification of the absorbent solution and reagent characteristics appropriate for Karl Fischer titration.
• Procedure for titration, blank determinations, calibration and result calculation (expressed as mass of water per cubic metre of gas at defined reference conditions).
• Performance limits and applicable measurement range; guidance on uncertainty contributors (sampling, reagent purity, titration precision).

Typical use and users

Used by natural gas testing laboratories, pipeline and gas-distribution quality control teams, custody-transfer testing facilities, equipment manufacturers (sampling cells and titration apparatus), and regulatory or standards bodies working on gas quality and moisture specification. National standards adopters and commercial standards resellers also distribute translated PDFs (including Russian-language versions) for local users.

Related standards

ISO 10101 is a multipart series; related documents include ISO 10101-1:1993 (Introduction and general requirements) and ISO 10101-3:1993 (other procedural variants), and the later revised edition ISO 10101-2:2022 (volumetric procedure) which replaces the 1993 titration procedure. Many national and regional adoptions exist (e.g., EN ISO 10101-2:1998 and national translations/adoptions).

FAQ

Q: What is this standard?

A: ISO 10101-2:1993 is an ISO international standard titled "Natural gas — Determination of water by the Karl Fischer method — Part 2: Titration procedure" that specifies a titrimetric (Karl Fischer) method for measuring water in natural gas.

Q: What does it cover?

A: It covers the procedure of passing a measured volume of gas through an absorbent, collecting water into the absorbent solution and determining the water by Karl Fischer titration, together with the design considerations for the absorption cell, reagent requirements, titration steps and calculation of results within the method's stated measurement range.

Q: Who typically uses it?

A: Gas-quality laboratories, pipeline and distribution operators, equipment manufacturers, and standards bodies — essentially any organization needing standardized, traceable moisture measurements in natural gas. Translated national/adopted versions (including Russian PDFs) are commonly used by non‑English-speaking laboratories and agencies.

Q: Is it current or superseded?

A: The 1993 edition has been withdrawn and a newer edition ISO 10101-2:2022 (volumetric procedure) has been published; users should consult the 2022 edition for the current ISO requirements. National or adopted versions based on the 1993 text (EN, DIN, etc.) may also have been updated or replaced.

Q: Is it part of a series?

A: Yes — ISO 10101 is a multipart series on determination of water in natural gas; Part 1 provides general requirements, Part 2 (this document) covered the titration procedure, and other parts address alternative procedures and guidance. The series has been updated in later editions.

Q: What are the key keywords?

A: Natural gas; water determination; Karl Fischer; titration; moisture measurement; sampling cell; gas quality; ISO 10101-2; rus PDF.
