I hope that this sheds some more light on the subject for you. I�m sorry but I don�t have any of these standards, though as they are CEN standards I would expect them to be somewhat pricey.

5.7 Standardised methods of analysis for additives
There are many organisations that publish standardised methods of analysis for additives, such methods normally having been validated through a collaborative trial organised to conform to one of the internationally accepted protocols described previously. Such organisations will include AOACI, the European Organisation for Standardisation (CEN) and the Nordic Committee for Food Analysis (NMKL). Within Europe, the most important of these international standardising organisations is probably CEN. CEN has a technical committee dealing with horizontal methods of analysis in which both additive and contaminant methods of analysis are discussed (TC 275). The methods of analysis for additives within its work programme are outlined below. This is given by Working Group. The titles under the Working Group heading refer to the work item (topic area) of that Working Group. The Working Groups not listed (e.g. 3, 4 etc.) are concerned with contaminant methods of analysis and have been discussed previously.20
