ASTM D976 / D4737 – Cetane Index

It may be conveniently employed for estimating cetane number when the quantity of sample available is too small for an engine rating. 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. E0 Standards Related Products 1. E0 Book of Standards Volume: Test Method D is the preferred method as estimator of cetane number.

As a supplementary tool, the Calculated Cetane Index by Four Variable equation must be used with due regard for its limitations. Aetm methods do measure the effect of cetane improver. Aatm Standards Related Products 1. The index value, as computed from the formula, is termed the Calculated Cetane Index. No other units of measurement are aatm in this standard.
