IS 15127 : 2024/ISO 13686 : 2013 Natural Gas - Quality Designation
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 13686 : 2013 'Natural gas - Quality designation' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Petroleum and their Related Products of Synthetic or Biological or Natural Origin Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.
This standard was originally published in 2002 and was an adoption of ISO 13686 : 1998 'Natural gas - Quality designation'. The first revision of this standard has been undertaken to align it with the latest version of ISO 13686 : 2013.
The text of the ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
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.
