The Precision of Knock Rating - 1936-1938 - Report from Cooperative Fuel Research Committee 390176
ON May 4, 1936, at the meeting of the CFR Detonation Subcommittee 1, the National Bureau of Standards presented the “Supplementary Report on Analysis of Detonation Rating Data,” which completed the first analysis of the Cooperative Exchange samples. This analysis 2 included the “first” and the “E” series of tests of Uniontown (1934) fuels and the first 67 Cooperative Exchange samples.
At the CFR Motor Fuels Section 1 meeting on Nov. 7, 1937, the Bureau was requested to make a second analysis of the Cooperative Exchange fuels since June, 1936.
This analysis is based on results of 6386 tests on 136 fuels. These tests were made by over 100 laboratories including laboratories of the CFR Exchange Group and a non-member group, with laboratories in foreign countries, invited to participate semi-annually.
