3 For Comments Only Doc:PCD3(2748)C ISO October 2013 DRAFT INDIAN STANDARD NATURAL GAS - QUALITY DESIGNATION (First Revision of IS 15127) Last date for comments 10 January 2014 ICS No NATIONAL FOREWORD (Formal clauses will be added later) The text of ISO Standard has been proposed to be approved as suitable for publication as 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. 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. In this adopted standard, reference appears to the following International Standard for which Indian Standard also exists. The corresponding Indian Standards which is to be substituted in its place is listed below along with its degree of equivalence for the edition indicated. International Standard Corresponding Indian Standard Degree of Equivalence ISO , Natural gas Identical IS 15130(Part 1):2002 Natural Gas - with and associated uncertainty by gas chromatography Part 1: chromatography: Part 1 Guidelines for General guidelines and tailored analysis calculation of composition ISO , Natural gas with defined uncertainty by gas chromatography Part 3: Determination of hydrogen, helium, oxygen, nitrogen, carbon dioxide and IS 15130(Part 3):2002 Natural Gas - with chromatography: Part 3 Determination of hydrogen, helium, inert gases and hydrocarbons up to C8 using two packed columns
