The work of preparing

9、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 committee. International organizations, governmental and non-governmental, in liaiso

10、n 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 accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of tec

11、hnical 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 requires approval by at least 75 % of the member bodies casting a vote. Attention is dra

12、wn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3045 was prepared by Technical Committee ISO/TC 54, Essential oils. This second edition cancels and replaces the

13、first edition (ISO 3045:1974), which has been technically revised. BSISO3045:2004blankINTENRATIONAL TSANDADR IS:5403 O4002(E)1Oil of bay Pimenta racemosa (Mill.) J.W.

18、 terms and definitions apply. 3.1 oil of bay essential oil obtained by steam distillation of the leaves of Pimenta racemosa (Mill.) J.W. Moore, of the Myrtaceae family. NOTE For information on the CAS number, see ISO/TR 21092. 4 Requirements 4.1 Appearance Clear mobile liquid. 4.2 Colour Dark brown.

31、 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 purposes, given that:

32、there is wide variation in the chemical compo- sition of essential oils; the volume of the sample needed in 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, users cannot be expected to

33、 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 specified. For further in

34、formation, see ISO/TR 11018. B.2 Flashpoint of the essential oil of bay The mean value is + 64 C. NOTE Obtained with “Luchaire” equipment.
