ISO 32662-2:2025

This document specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in neat fatty acid methyl esters (FAME). The working range is from 5mg/kg to 27mg/kg and it was established in an interlaboratory study by applying ISO4259-1.[1]

This document in general is applicable to FAME having a kinematic viscosity not exceeding 8mm²/s at 20°C, or 5mm²/s at 40°C, e.g. as specified in EN14214.[2]

This test method can be used for FAME having a kinematic viscosity exceeding 8mm²/s at 20°C, or 5mm²/s at 40°C, however in such cases the precision of the test method has not been determined.
