13、 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

14、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. International Standards are drafted in acc

15、ordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requ

38、fety reasons, transport companies, insurance companies, and people in charge of safety services require information on the flashpoints of essential oils, which in most cases are flammable products. A comparative study on the relevant methods of analysis (see ISO/TR 11018) concluded that it was diffi

39、cult to recommend a single apparatus for stan- dardization purposes, given that: there is a wide variation in the chemical compo- sition of essential oils; the volume of the sample needed in certain re- quirements would be too costly for high-priced essential oils; as there are several different typ

40、es of equip- ment 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 value for the flashpoint in an informative annex to each International Standard, for information, in order to meet the requirements of the i

41、nterested parties. The equipment with which this value was obtained should be specified. For further information see ISO/TR 11018.
