ASTM D976 / D4737 – Cetane Index

Errors may be greater for fuels whose properties fall outside the recommended range of application. E0 Standards Related Products 1. Active view current version of axtm. No other units of measurement are included in this standard.

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. 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 d737 improver is not used.

It may be conveniently employed for estimating cetane number when the quantity of sample available is too small for an engine rating. No other units of measurement are included in this standard. Note 1—Sxx is the designation for maximum sulfur level specified for the grade.

ASTM D – 96a Standard Test Method for Calculated Cetane Index by Four Variable Equation

In cases where the cetane number of a fuel has been initially established, the index is useful as a cetane number check on subsequent satm of that fuel, provided its source and mode of manufacture remain unchanged. E0 Standards Related Products 1. 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.

This method for estimating cetane number was developed by Chevron Research Co. Historical Version s – view previous versions of standard Translated Version s: As a supplementary tool, the Calculated Cetane Index by Four Variable equation must be used with due regard for its limitations.

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.

The index value, as computed from the formula, is termed the Calculated Cetane Index. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
