5、l Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been es
6、tablished 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. IS0 collaborates closely with the International Electrotechnical Com- mission (IEC) on all matters of electrotechnical standar
7、dization. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. 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
8、75 % of the member bodies casting a vote. International Standard IS0 8902 was prepared by Technical Committee ISOTTC 54, Essential oils. This second edition cancels and replaces the first edition (IS0 8902:1987), which has been technically revised. Annexes A and B of this International Standard are

37、 in most cases are flammable products. A comparative study on the relevant methods of analysis (see ISOTTR 1081) concluded that it was hard to find a single method for standardization purposes, given that: - essential oils are varied and their chemical com- positions differ to a large extent; - the
38、volume of the sample needed for certain test equipment is incompatible with the high price of essential oils; - there are different types of equipment that satisfy the desired objective, but users cannot be obliged to use one type of equipment rather than another. IS0 8902:1999(E) Consequently, it w
39、as decided to give a mean value for the flashpoint in an informative annex in each International Standard, for information purposes, in order to meet the requirements of the interested parties. If possible, the method by which this value was obtained should be specified. For further information see
40、ISOTTR 0181). 6.2 Flashpoint of the essential oil of lavandin Grosso, French type The mean value is +75 “C. NOTE 1 Obtained with “Setaflash“ equipment. The mean value is +78 O C .
