Full title and description

St ISO 10715-2022 — ISO 10715:2022, Natural gas — Gas sampling. This international standard specifies principles, methods and procedures to obtain representative samples of natural gas and natural gas substitutes conveyed into transmission and distribution networks for interchangeability, energy-content and fiscal measurement purposes.

Abstract

ISO 10715:2022 provides guidance and requirements to ensure that samples of natural (dry) gas and suitable substitutes are representative of the mass being allocated. It covers sampling at transmission and distribution entry/exit points and at locations where interchangeability criteria, energy content and network-entry conditions are measured and monitored (including cross-border and fiscal measurement stations). The document is limited to single-phase (dry) natural gas sampling and explicitly excludes procedures for wet (multi-phase) gas and does not address safety aspects of sampling operations.

General information

Scope

The standard applies to sampling practices for natural dry gas (single-phase) and natural gas substitutes transported in pipelines and conveyed into transmission and distribution grids where measurements of energy content, interchangeability and network-entry criteria are required. It addresses where and how to take spot, incremental (composite) and online samples, sample containment and handling to maintain representativeness and traceability. It does not cover sampling of wet (two- or three-phase) gas flows nor the occupational safety aspects of sampling operations.

Key topics and requirements

• Fundamental principles of sampling and the concept of a representative sample (definition and criteria).
• Types of sampling: spot (fill-and-empty, controlled-rate, evacuated-cylinder, helium pre-fill, floating-piston, single-cavity cylinders), incremental (composite) sampling and online/direct sampling.
• Requirements for sampling system design, monitoring of filling processes, overpressure protection and automatic drainage for online systems.
• Sample cylinder selection, filling methods, cylinder tracking, labelling and chain-of-custody to preserve sample integrity.
• Sampling frequency, intervals and statistical considerations for composite sampling.
• Normative reference to vocabulary and definitions to ensure consistent terminology (ISO 14532 referenced).
• Exclusions and limitations: wet gas (multi-phase) sampling and safety procedures are outside the scope.

Typical use and users

Used by transmission and distribution network operators, pipeline and meter station engineers, fiscal and custody-transfer measurement personnel, gas analysis laboratories, regulatory bodies and consultants responsible for ensuring accurate composition and energy-content determinations. Equipment manufacturers, system integrators and operators use the standard to design sampling skids, sample-handling systems and quality-control procedures.

Related standards

ISO 10715:2022 references ISO 14532 (natural gas vocabulary) as a normative source and is intended to work alongside other natural-gas measurement and analysis standards such as the ISO/EN series for gas composition and property measurement (for example ISO 6974 series for gas composition and ISO 15970 for volumetric properties) and analytical methods for trace components and water (e.g., ISO 10101‑1). The ISO text has been endorsed/adopted as EN ISO 10715:2022 for European application.

FAQ

Q: What is this standard?

A: ISO 10715:2022 is an international standard titled "Natural gas — Gas sampling" that specifies principles and procedures to obtain representative samples of natural (dry) gas and natural gas substitutes for measurement and quality/control purposes.

Q: What does it cover?

A: It covers sampling methods (spot, incremental/composite and online), sampling-system design considerations, cylinder filling and handling, sample traceability and monitoring of sampling processes for single‑phase (dry) natural gas. It excludes wet (multi‑phase) gas sampling and does not address safety requirements.

Q: Who typically uses it?

A: Pipeline and network operators, custody-transfer/fiscal measurement staff, gas analysis laboratories, equipment manufacturers and regulatory agencies involved in natural gas measurement and quality control.

Q: Is it current or superseded?

A: It is the current edition (2nd edition, published October 2022). It supersedes and replaces ISO 10715:1997.

Q: Is it part of a series?

A: It forms part of the body of ISO standards addressing natural gas measurement, sampling and analysis developed under ISO/TC 193 (and its relevant subcommittees). It is intended to be used together with related standards for gas composition, property measurement and analytical methods.

Q: What are the key keywords?
