10、iiiForeword 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
11、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 matt
12、ers of electrotechnical standardization. International 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 Standards adopted by the technical committees are circul
13、ated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsib
14、le for identifying any or all such patent rights. ISO 14717 was prepared by Technical Committee ISO/TC 54, Essential oils. This second edition cancels and replaces the first edition (ISO 14717:1999), which has been technically revised. BS ISO 14717:2008BS ISO 14717:2008INTERNATIONAL STANDARD ISO 147

37、st cases are flammable products. A comparative study on the relevant methods of analysis (see ISO/TR 110181) 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 volume o
38、f the sample needed for certain requirements would be too costly for highly priced essential oils; as there are several different types 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 fo
39、r the flashpoint in an annex to each International Standard, for information, in order to meet the request of the interested parties. The equipment with which this value was obtained has to be specified. For further information see ISO/TR 110181. B.2 Flashpoint of the essential oil of origanum, Span
