Natural gas. Measurement of properties. Calorific value and Wobbe index Ingestion-build-239834 Revision of terms and definitions1 Scope This International Standard concerns the measurement of calorific value of natural gas and natural gas substitutes by non separative methods, i. e. methods that do not involve the determination of the gas composition nor calculation from it. It describes the principles of operation of a variety of instruments in use for this purpose, and provides guidelines for the selection, evaluation, performance assessment, installation and operation of
