ÖNORM EN ISO 3657

Issue date: 2023 11 15

Animal and vegetable fats and oils - Determination of saponification value (ISO 3657:2023)

This document specifies a method for the determination of the saponification value of animal and vegetable fats and oils. The saponification value is a measure of the free and esterified acids present in fats and fatty acids. The method is applicable to refined and crude vegetable and animal fats. If mineral acids are present, the results given by this method are not interpretable unless the mineral acids are determined separately. The saponification value can also be calculated from fatty acid data obtained by gas chromatography analysis as given in Annex B. For this calculation, it is necessary to be sure that the sample does not contain major impurities or is thermally degraded.

Frequently Asked Questions about ÖNORM EN ISO 3657

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
