Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

This third edition cancels and replaces the second edition (ISO 150:2006), which has been technically revised.

The main changes compared to the previous edition are as follows:

— the determination of the composition of fatty acids in accordance with ISO 12966 has been specified;
— ISO 2811‑3 (oscillation method) has been added for determination of density;
— the determination of drying time has been deleted;
— reference to the use of the Lovibond colour system as an alternative to the Gardner colour scale has been deleted because the visual method is too inaccurate;
— sampling in accordance with ISO 15528 has been replaced by sampling in accordance with ISO 5555;
— the preparation of samples in accordance with ISO 661 has been added;
— the standard values for the composition of fatty acids have been revised;
— the normative references in Clause 2 have been updated and the text has been editorially revised.
