D613-Standard Test Method for Cetane Number of Diesel Fuel Oil.
Get more information about the standard at RR:D02-1879.
ASTM D613 is a globally recognized standard for determining the cetane number of diesel fuel oils. The cetane number is a critical indicator of a fuel’s ignition quality and combustion performance. This test method involves using a standardized diesel engine to measure the fuel’s ignition delay and compare it to reference fuels with known cetane numbers. By providing a reliable means of assessing diesel fuel quality, ASTM D613 supports engine efficiency, regulatory compliance, and emissions reduction.
Details
The method described in ASTM D613 ensures precise and reproducible results through a controlled testing process. The procedure involves running a diesel engine under specified operating conditions and measuring the ignition delay of the test fuel. The ignition delay is then compared to a scale derived from reference fuels with established cetane numbers.
The cetane number is crucial for assessing how quickly and efficiently a diesel engine fuel ignites after injection. The cetane number is a key parameter for diesel engine operation, directly influencing ignition performance, fuel efficiency, and emissions. ASTM D613 provides a standardized and reliable method for determining this critical property, supporting safety, efficiency, and environmental goals across diverse applications. By adhering to ASTM D613, stakeholders can ensure diesel fuel quality, reduce operational risks, and maintain compliance with global standards.
