4、 ii Foreword 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
5、 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 Com- mission (IEC) on all m
6、atters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stan
7、dard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 4719 was prepared by Technical Committee ISO/TC 54, Essential oils. This second edition cancels and replaces the first edition (ISO 4719:1983), which has been technically revised. Annexes A and B

34、mative) Flashpoint B.1 General information For reasons of safety, transport companies, insurance companies, people in charge of safety services, etc., require information on the flashpoint of essential oils, which in most cases are flammable products. A comparative study on the relevant methods of a
35、nalysis (see ISO/TR 110181) 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 volume of the sample needed for certain test equipment is incompatible with the high pric
36、e 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. Consequently, it was decided to give a mean value for the flashpoint in an informative annex in each Inter- national Standard,
37、 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 ISO/TR 110181). B.2 Flashpoint of the essential oil of spike lavender, Spanish type The mean value is + 60
