Testing of gasoline blend stocks or other process stream materials can produce ratings at various levels throughout the Research O. A number of controlled field trials, comparative tests and commercial x2699 confirm that the ZXC is providing a safe indication of the octane rating of unleaded motor fuels and of the cetane rating of all diesels.
E Terminology Relating to Thermometry and Hydrometry. This standard is not included in any packages. Results are traceable to official knock engine laboratory. Testing of gasoline blend stocks or other process stream materials can produce ratings at various levels throughout the Research O. The standardized CFR engine measurements continue to be in inch-pound units only because of the extensive and expensive tooling that has been created for this equipment.
The sample fuel is tested using a standardized single cylinder, four-stroke cycle, variable compression ratio, carbureted, CFR engine run in accordance with a defined set of operating conditions.
