This International Standard specifies the parameters required to describe finally processed and, where required, blended natural gas. Such gas is
referred to subsequently in this text simply as "natural gas".
The main text of this standard contains a list of these parameters, their units and references to measurement standards. Informative annexes give examples of typical values for these parameters, with the main emphasis on health and
safety.
In defining the parameters governing composition, physical properties and trace constituents, consideration has also been given to existing natural gases to ensure their continuing viability.
The question of interchangeability is dealt with in annex A clause A.2.
