BS ISO 3475 This document specifies certain characteristics of the essential oil of aniseed (Pimpinella anisum L.),with a view to facilitating the assessment of its quality.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For

ISO/TS 211, Essential oils – General rules for labelling and marking of containers ISO 212, Essential oils一Sampling ISO 279, Essential oils – Determination of relative density at 20 degrees C一Reference method ISO 280, Essential oils – Determination of refractive index ISO 592, Essential oils一Determination of optical rotation ISO 875, Essential oils一Evaluation of miscibility in ethanol ISO 1041, Essential oils – Determination of freezing point ISO 11024 (all parts), Essential oils一General guidance on chromatographic profiles.For 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 relevant methods of analysis (see ISO/TR 11018) 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 for certain test equipment is incompatible with the high price of 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 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.BS ISO 3475 pdf download.
