9、 BS ISO 3761:2005ii 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

10、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 Commissi

11、on (IEC) on all matters 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 c

12、ommittees are circulated 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 n

13、ot be held responsible for identifying any or all such patent rights. ISO 3761 was prepared by Technical Committee ISO/TC 54, Essential oils. This third edition cancels and replaces the second edition (ISO 3761:1997), which has been technically revised. It also cancels and replaces ISO 7353:1985. BS

34、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 difficult to recommend a single apparatus for standardization

35、 purposes, given that: there is wide variation in the chemical composition of essential oils; the volume of the sample needed to meet certain requirements would be too costly for high-priced essential oils; as there are several different types of equipment which can be used for the determination, us

36、ers 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, in order to meet the requirements of the interested parties. The equipment with which this value was obtained should be

37、specified. For further information, see ISO/TR 11018. B.2 Flashpoint of the oil of rosewood, Brazilian type The mean value is +67 C. NOTE Obtained with “Setaflash” equipment.
