Diesel laboratories may also do the following tests:

Cetane Number Testing: Measures the combustion quality of diesel fuel Testing
indicating how quickly and efficiently it burns Testing
Sulfur Content Analysis: Determines the sulfur content to ensure compliance with environmental regulations Testing
Density and Viscosity Testing: Assesses the fuel's physical properties Testing
which affect engine performance and fuel handling Testing
Cold Filter Plugging Point (CFPP): Tests the lowest temperature at which diesel remains pourable Testing
critical for cold-weather performance Testing
Water and Sediment Content: Evaluates the purity of the fuel and its potential to cause engine wear or damage Testing
