8、t license from IHS -,-,- ISO 3526:2005(E) ISO 2005 All rights reserved iii 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 t
9、echnical 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 liaison with ISO, also take part in the work. ISO collaborates clos
10、ely 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 technical committees is to prepare International Standards. Draf
11、t 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 drawn to the possibility that some of the elements of this docum
12、ent may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3526 was prepared by Technical Committee ISO/TC 54, Essential oils.

37、 insurance companies, 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 of the relevant methods of analysis (see ISO/TR 11018) concluded that it was difficult to recommend a single apparat
38、us for standardization purposes, given that: there is wide variation in the chemical composition of essential oils; the volume of the sample needed for certain requirements would be too costly for high- priced essential oils; as there are several different types of equipment which can be used for th
39、e determination, users 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 o
40、btained should be specified. For further information, see ISO/TR 11018. B.2 Flashpoint of the essential oil of sage, Spanish The mean value is + 49 C. NOTE Obtained with “Setaflash” equipment.
