This part of ISO 18363 describes a rapid procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3-MCPD esters (bound 3-MCPD) and glycidyl esters (bound glycidol) in a single assay, based on alkaline catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC-MS/MS analysis.This method is applicable to solid and liquid fats and oils. This part of ISO 18363 can also apply to animal fats and used frying oils and fats, but a validation study must be undertaken before the analysis of these matrices.Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this international standard.

This document specifies the procedures to be adopted when checking transportable refillable LPG cylinders before, during and after filling.This document applies to transportable refillable LPG cylinders of water capacity not exceeding 150 l and deemed to be fitted with valves designed according to EN ISO 14245 [4] and EN ISO 15995 [5].This document does not cover the requirements for filling LPG cylinders that are designed and equipped for filling by the user.This document does not cover the requirements for filling LPG containers on vehicles.This document is applicable to the following: - welded and brazed steel LPG cylinders with a specified minimum wall thickness (see EN 1442 and EN 12807 [1] or an equivalent standard);- welded steel LPG cylinders without specified minimum wall thickness (see EN 14140 or an equivalent standard);- welded aluminium LPG cylinders (see EN 13110 [2] or an equivalent standard);- composite LPG cylinders (see EN 14427 or an equivalent standard); and- over-moulded cylinders (OMC).Specific requirements for the different types of cylinders are detailed in Annex A, Annex B, Annex C, Annex D and Annex G.This draft standard is intended to be applied to cylinders complying with RID/ADR [6] [7] (including pi marked cylinders) and also to existing non RID/ADR cylinder populations.

This document describes a method to firstly identify the specific nature of oils spilled in the environment and secondly compare the chemical composition of spilled oil or oily samples with that of suspected sources. Specifically, the document describes the detailed analytical methods and data processing specifications for identifying the specific nature of oil spills and establishing their correlation to suspected sources. Even when samples or data from suspected sources are not available for comparison, establishing the specific nature (e.g. refined petroleum, crude oil, waste oil, etc.) of the spilled oil may still help constrain the possible source(s) of the spilled oil.This methodology is restricted to petroleum related products containing a significant proportion of hydrocarboncomponents with a boiling point above 150°C. Examples are: crude oils, higher boiling condensates, diesel oils, residual bunker or heavy fuel oils, lubricants, and mixtures of bilge and sludge samples, as well as distillate fuels and blends. While the specific analytical methods may not be appropriate for lower boiling oils (e.g. kerosenes, jet fuels, or gasoline), the general concepts described in this methodology, i.e. statistical comparison of weatheringresistant diagnostic ratios, may have applicability in spills involving lower boiling oils.Paraffin as petroleum product (for candles, etc.) is outside the scope of this method, because too many compounds have been removed during the production process. Still the method can be used to analyse the type of product involved.
