ISO 15971 is an ISO
standard for calorific value measurement of natural gas
and its substitutes. The methods it covered does not involve gas composition
determination and the related calculations.
The standard includes the operation of instruments that are used in the measurements and the guidelines in selecting and assessing, as well as the installation and the operation of such instruments.

standard for calorific value measurement of natural gas
Natural gas
Natural gas is a naturally occurring gas mixture consisting primarily of methane, typically with 0–20% higher hydrocarbons . It is found associated with other hydrocarbon fuel, in coal beds, as methane clathrates, and is an important fuel source and a major feedstock for fertilizers.Most natural...
