Abstract

A high precision of octane number measurement according to standard measurement and to standard requirement is a must in the refining industry. The ASEAN Council on Petroleum (ASCOPE) Correlation Programme is conducted to obtain the precision of octane number measurement data for gasoline the normally used methods of ASTM D 2699 and IP 239. This programme is participated by 19 petroleum laboratories in ASEAN Countries. The test results of the various participating laboratories are subjected to statistical analysis to determine their average value, variance, standard deviation, and to rejected the outlier values. The Grubb T-Test method was used for the statistical rejection of outliers. This method appears to be quite satisfactory for ASCOPE purpose. The implementation of the Grubb T-Test ensures the laboratory consistency and this in turn will give the buyers or sellers of the gasoline confidence in the quality of the gasoline This paper presents the results of 26 ASCOPE Laboratories Test Correlation Programme for Octane Number Measurement (1999).

Abstract

There are two basic incentives in blending MTBE in gasoline for a country like Indonesia , te. To improve the octane quality and to reduce the lead content in gasoline. Changes in physical and chemical properties of gasoline will also occur, accompanying the improvement of the octane number. The blends used in this study were made in four concentrations, viz 3, 6, 10 and 15 volume percent MTBE in unleaded gasoline. The test results were compared to the indonesian specification of premium gasoline.

Abstract

In ASEAN we have the ASCOPE correlation programme on CFR engine laboratory to obtain precision data in the gasoline by CFR test research method. Member countries taking part in the 6th Laboratory test correlation program for CFR engine are Indonesia as coordinator with seven laboratories participating, Malaysia with one laboratory, Philippines and Thailand with two laboratories each, Singapore and USA with one laboratory each.

Abstract

A high precision CFR Engine Laboratory operating according to standard requirement is a must in the oil industry, It is also of very high importance within work of research activities on the use of hydrocarbon fuels. In ASEAN we have the ASCOPE correlation program on CFR engine laboratory to obtain precinion data in the gusoline by CFR test research method.  Member countries taking part in the 5 laboratory test correlation program for CFR engines are Indonesia as coordinator with six participating laboratories, Malaysia, Philippines, Singupore and Thailand with two laboratories each and USA with are laboratory. The 5th correlation program was started by sending sample by the program correlation in Jamuary, 1983 after being tested the participating laboratories, the test renilt were sent to the program coordinator who procured the result for the determination of standard deviation according to precision and statistics.  Based on result, conclusion can be drawn about the deviation of laboratory test results.
