Introduction
This document is based on EN ISO 3961 [1] which was specifically adapted for the determination of
iodine value of Fatty Acid Methyl Esters (FAME).
1 Scope
This document specifies a titrimetric method for the determination of iodine value in Fatty Acid Methyl
Esters, hereinafter referred as FAME.
The precision statement of this test method was determined in a Round Robin exercise with iodine values
in the range 111 g iodine/100 g to 129 g iodine/100 g.
The test method is also applicable for lower iodine values; however, the precision statement is not
established for iodine values below 111 g iodine/100 g.
