GB 253-2008Kerosene (English PDF)

Foreword

Chapter 4 of this standard is mandatory, the rest are recommended.

The standard American Society for Testing and Materials ASTMD3699-05 "kerosene standards" (in English) the consistency of non-equivalent.

This standard ASTMD3699-05 main differences.

--- Color is divided into two files, No. 1 kerosene color is not less than a predetermined number +25,2 kerosene chroma technical requirements of ASTM

D3699-05 not less than +16;

--- Increased mechanical impurities and water, water-soluble acid or alkali, the density indicators;

--- Flammability and smoke point allows the use of substitute 16h 8h test test;

--- No. 2 kerosene sulfur content of not more than by the technical requirements of 0.30% (mass fraction) to not more than 0.10% (mass fraction);

--- Copper Corrosion by the technical requirements of not more than three, to no more than Grade 1;

--- Canceled distillation range of simulated distillation test items.

This standard replaces GB 253-1989 "kerosene." The main changes in this standard with the GB 253-1989.

--- Grades original standard superior grade, first grade and qualified, to No. 1 and No. 2 standard;

--- Chrominance index the original standard grade product, first grade and qualified products are not less than + 25, + 19, + 13, instead of the standard

No. 1 is not less than the number +25,2 not less than +16;

--- Mercaptan sulfur, flash point, kinematic viscosity, copper corrosion, flammability, smoke point and other indicators have been revised accordingly;

--- Increasing the sulfur content of the test method, a clear arbitration;

--- Increasing the freezing point, density test method, a clear arbitration;

--- Copper etching time from 2h to 3h;

--- Cancel the cloud point indicator and test methods.

This standard by the National Standardization Technical Committee on products and lubricant oil (SAC/TC280) proposed.

The standard by the China Petroleum and Chemical Corporation.

This standard was drafted. China Petroleum and Chemical Corporation Maoming Branch.
