The work of preparing International Standa
11、rds 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 liaison with ISO, also tak
12、e 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 technical committees is
13、 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 drawn to the possibilit
14、y 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 8902 was prepared by Technical Committee ISO/TC 54, Essential oils. This third edition cancels and replaces the second edition (ISO 8

35、B (informative) Flashpoint B.1 General information For safety reasons, transport companies, insurance companies and people in charge of safety services require information on the flash points of essential oils, which in most cases are flammable products. A comparative study on the relevant methods o
36、f analysis (see ISO/TR 11018 1 ) concluded that it was difficult to recommend a single apparatus for standardization purposes, given that: there is a wide variation in the chemical composition of essential oils; the volume of the sample needed for certain equipment is incompatible with the high pric
37、e of essential oils; as there are several different types of equipment which can be used for the determination, users cannot be expected to use one specified type only. Consequently, it was decided to give a mean value for the flashpoint annexed to each International Standard, for information, in or
38、der to meet the requirements of the interested parties. The equipment with which this value was obtained has to be specified. For further information, see ISO/TR 110181 . B.2 Flashpoint of the essential oil of lavandin Grosso (Lavandula angustifolia Mill. Lavandula latifolia Medik.), French type The
39、 indicative value is + 75 C (see Note 1) or + 78 C (see Note 2). NOTE 1 Value obtained with a Setaflash 1)appliance. NOTE 2 Value obtained with a Luchaire 1)appliance. 1) Equipment available commercially. This information is given for the convenience of users of this International Standard and does
