33、ISO 4719:2012(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 comparative study on the

34、 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 requirements would be too cost

35、ly 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 Standard, for inform

36、ation, 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 11018.1B.2 Flashpoint of the essential oil of spike lavenderThe mean value is +60 C.NOTE Obtained with Setaflash1)equipment.1) Eq
