Foreword
This section drafted in accordance with GB/T 1.1-2009 given rules.
SN/T 0041 "export naphtha PONA value test method" is divided into four parts.
--- Part 1. General procedures;
--- Part 2. Gasoline and naphtha depentanizer law;
--- Part 3. Determination of Canadian petroleum fraction olefins aromatic content;
--- Part 4. off than spectrophotometric determination saturated hydrocarbon fraction naphthenic.
This section SN/T 0041 "export naphtha PONA value test methods" Part 1.
This Part replaces SN 0041-1992 "export naphtha PONA value test method."
The main difference between this part and SN 0041-1992 follows.
--- The "reference standard" to "normative references";
--- The "Summary of Method" to "Method summary";
--- The "average density olefin" to "olefin content and volume fraction of the conversion factor";
--- The "accurate to the decimal point after the first 'to' one decimal place."
