The work of preparing International Standards is normally carried out through ISO technical
11、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
12、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 fo

37、n most cases, are flammable products. A comparative study on the relevant methods of analysis (see ISO/TR 11018 1 ) concluded that it was difficult to recommend a single apparatus for standardization purposes, given that there is a wide variation in the chemical composition of essential oils, the vo
38、lume of the sample needed in certain requirements would be too costly for high-priced essential oils, and as there are several different types of equipment which can be used for the determination, users cannot be expected to use one specified type only. Consequently, it was decided to give a mean va
39、lue for the flashpoint annexed to each International Standard, for information, in order to meet the requirements of the interested parties. The equipment with which this value was obtained has to be specified. For further information, see ISO/TR 11018. 1 B.2 Flashpoint of the essential oil of hysso
