11、es). The work of preparing 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

12、non-governmental, in liaison 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, Pa

13、rt 2.The main task of technical 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

14、 a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

41、 7BS ISO 3528:2012ISO 3528:2012(E)Annex B (informative) FlashpointB.1 General informationFor safety reasons, transport companies, 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 compar

42、ative study on the relevant methods of analysis (see ISO/TR 110181) 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 in certain requiremen

43、ts 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 use one specified type only.Consequently, it was decided to give a mean value for the flashpoint annexed to each International

44、 Standard, for information, in order 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 mandarin, Italian typeThe mean value is +48 C.NOTE Obtained w
