33、 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 of analysis (see ISO/TR 110181) concluded that it was difficult to recommend a single appar

34、atus 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 test equipment is incompatible with the high price of essential oils; as there are several different types of equipment which can be use

35、d 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 order to meet the requirements of the interested parties. The equipment with which this v

36、alue was obtained has to be specified. For further information, see ISO/TR 110181. B.2 Flashpoint of the essential oil of sweet orange Citrus sinensis (L.)
