The work of preparing International Standards is normally carried out
11、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 non-governmental, in liaison with ISO, also take part in the work. ISO coll
12、aborates 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, Part 2.The main task of technical committees is to prepare International Stan
13、dards. 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 a vote.Attention is drawn to the possibility that some of the elements of

ISO shall not be held responsible for identifying any or all such patent rights.ISO 10115 was prepared by Technical Committee ISO/TC 54, Essential oils.This second edition cancels and replaces the first edition (ISO 10115:1997) which has been techni

36、rmationFor safety reasons, transporters, insurance companies, safety department officials, etc., insist on knowing the flashpoint of essential oils which, in most cases, are inflammable products.A comparative study of the appropriate methods of analysis (see ISO/TR 110181) found that it was difficul
37、t to standardize a single method, because: there is a very large number of essential oils and their chemical composition varies considerably; the sample volume recommended for use with certain appliances is incompatible with the high price of the essential oils; users cannot be under obligation to p
38、urchase one type of appliance rather than another from the moment that several appliances which can meet the desired objective exist.Consequently, it was decided to give a mean value for the flashpoint annexed to each research study, and solely by way of indication, in order to meet the request of t
39、he relevant departments.As far as possible, the method by which this value was obtained will be specified.For all additional information, see ISO/TR 110181.B.2 Flashpoint of the essential oil of tarragon (Artemisia dracunculus L.)The mean value is + 70 C.NOTE Value obtained using a Setaflash equipme
