35、flashpoints of essential oils, which in most cases are flammable products.A comparative 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 co

36、mposition of essential oils; the volume of the sample needed in certain requirements 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

37、 was decided to give a mean value for the flashpoint annexed to each International 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 11018.1B.2 Flashpoint of t
