Active view current version of standard Translated Standard: This method for estimating cetane number was developed by Chevron Research Co.

Generally, it has been found that use of Test Method D results in less offset than use of Test Method D, but there can be specific cases where this is not true. As a supplementary tool, the Calculated Cetane Index by Four Variable equation must be used with 4d737 regard for its limitations. As a supplementary tool, the Calculated Cetane Index by Four Variable equation must be used with due regard for its limitations.

ASTM D – 10 Standard Test Method for Calculated Cetane Index by Four Variable Equation

Test Method D is the preferred method as estimator of cetane number. It may be employed for approximating cetane number where the quantity of sample is too small for an engine rating. Link to Active This link will always route to the current Active version of the standard.

Errors may be greater for fuels whose properties fall outside the recommended range of application. Link to Active This link will always route to the current Active version of the standard. It may be conveniently employed for estimating cetane number when the quantity of sample available is too small for an engine rating.

This test method is temporarily retained because the proposal to the U. No other units of measurement are included in this standard. These methods do measure the effect of cetane improver. 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.

This method for estimating cetane number was developed by Chevron Research Co. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

EPA to control diesel fuel aromatics concentrations via a 40 Calculated Cetane Index minimum is based on the correlation between Test Method D and asym concentration.

This method for estimating cetane number was developed by Chevron Research Co.

In cases where the ASTM cetane number of a fuel has been previously established, the Calculated Cetane Index by Four Variable Equation is useful as a cetane number check on subsequent batches of that fuel, provided the fuel’s source and mode of manufacture remain unchanged.

Procedure A is based on a data set including a relatively small number of No. It is a supplementary tool for estimating cetane number when a result by Test Method D is not available and if cetane improver is not used.
