This Indian Standard which is identical with ISO 13686 : 1998`Natural gas - Quality designation issued by the InternationalOrganization for Standardization (ISO) was adopted by the Bureau ofIndian Standards on the recommendation of the Natural Gas SectionalCommittee and approval of the Petroleum, Coal and Related ProductsDivision Council.

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
