Total Acid Number ASTM D664 - Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration New and used petroleum products, biodiesel and blends of biodiesel may contain acidic constituents that are present as additives or as degradation products formed during service, such as oxidation products. The relative amount of these materials can be determined by titrating with bases. The acid number is a measure of this amount of acidic substance in the oil, always under the conditions of the test. The acid number is used as a guide in the quality control of lubricating oil formulations. It is also sometimes used as a measure of lubricant degradation in service. Any condemning limits must be empirically established. Closing Closing Proficiency Testing Scheme Schedule Page 4 of 16 Issue : 29/01/2015 Print : 25/06/2018
Viscosity ASTM D5293 - The CCS apparent viscosity of automotive engine oils correlates with low temperature engine cranking. CCS apparent viscosity is not suitable for predicting low temperature flow to the engine oil pump and oil distribution system.

Colour ASTM D156 - Standard Test Method for Saybolt Colour of Petroleum Products For the determination of the colour of petroleum products such as undyed motor and aviation gasoline, jet fuels, napthas and kerosine, using the Saybolt Colour scale. Where the colour of the petroleum product is darker than -16 Saybolt Colour, then the ASTM D1500 colour scale should be used.

Density ASTM D4052 - Standard Test Method for Density and Relative Density of Liquids by Digital Density Meter For the determination of density, relative density and API Gravity of those petroleum distillates and oils that can be handled in a normal manner at the required test temperature, either by manual or automatic injection. The method is restricted to those materials that have a total vapour pressure typically below 100 kpa and have a viscosity typically below 15,000 mm2/s (cst) at the test temperature. It is allowed to exceed the vapour pressure limit as long as it can be seen that no air bubbles form in the U-shaped oscillating tube during the test. Examples of such products are gasoline, diesel, aviation fuel, basestocks and lubricating oils. Closing Closing Proficiency Testing Scheme Schedule Page 7 of 16 Issue : 29/01/2015 Print : 25/06/2018
Flash Point ASTM D93, Proc. A - Standard Test Method for Flash Point by Pensky-Martens Closed Cup Tester For the determination of the flash point of petroleum products that can be found in the temperature range of between 40 370 C, whether by manual or automated Pensky-Martens closed cup flash apparatus. Procedure A is applicable to any new and in use lubricants, diesel, biodiesel blends, kerosene, heating oils and turbine fuels that are not found in the scopes for procedures B or C.
