A number of controlled field trials, comparative tests and commercial experience confirm that the ZXC is providing a safe indication asgm the octane rating of unleaded motor fuels and of the cetane rating of all diesels. The values in parentheses are the historical inch-pound units. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and aatm the applicability of regulatory limitations prior to use.

Values of k 1k 2and k 3 vary with vehicles and vehicle populations and are based on road-O. If the document is revised or amended, you will be notified by email.

Testing of gasoline blend stocks or other process stream materials can produce ratings at various levels throughout the Research O. Subscription pricing is determined by: Such measurements do not require sample preparation and do not damage the sample being measured.

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. Results are traceable to official knock engine laboratory.

However, this test method may not be applicable to fuel and fuel components that are primarily oxygenates. To perform a test, just pour ml of gasoline or diesel in the supplied sample container 75 mm optical path length and place it in the instrument.

However, this test method may not be applicable to fuel and fuel components that satm primarily oxygenates. The tester can be calibrated for ten fuels or substrates and measures all grades of unleaded gasoline.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The values in parentheses are the historical inch-pound units.

Testing of gasoline blend stocks or other process stream materials can produce ratings at various levels throughout the Research O. In unleaded gasoline, the light is absorbed at specific known wavelengths.

The NIR portion of the spectrum is where the wavelengths of light are xstm longer than can be seen by the human eye.

ASTM D – 18 Standard Test Method for Research Octane Number of Spark-Ignition Engine Fuel

Testing of gasoline blend stocks or other process stream materials can produce ratings d6299 various levels throughout the Research O. This is more commonly presented as: We have no amendments or corrections for this standard.

A NIR measurement requires a stable light source, a means of selecting the desired wavelengths from the light source, an enhanced silicon detector to measure the light before and after it illuminates the product and a built-in microprocessor system to convert the detector output to octane rating.
