18、nization for Standardization) is a worldwide federation of national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished
19、 has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization.Inte
20、rnational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publicati

23、rbidity (clarity) have been changed. The maximum acid value for alkali-refined linseed oil has been changed to . The determination of unsaponifiable-matter content, foots, colophony (rosin), fish oil and mineral acid havebeen deleted because they are no longer necessary. The determination of volatil
24、e-matter content has been replaced by the determination of water content. The determination of ash has been deleted because it is not required very often.
