ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in acc

38、fety 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 relevant methods of analysis (see ISO/TR 11018) concluded that it was diffi

39、cult to recommend a single apparatus for stan- dardization purposes, given that: there is a wide variation in the chemical compo- sition of essential oils; the volume of the sample needed in certain re- quirements would be too costly for high-priced essential oils; as there are several different typ

40、es of equip- ment 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 in an informative annex to each International Standard, for information, in order to meet the requirements of the i

41、nterested parties. The equipment with which this value was obtained should be specified. For further information see ISO/TR 11018.
