The purpose of this European Standard is to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME) intended for addition to mineral oils. The total glycerol content is then calculated from the obtained results.
Under the conditions described, the quantification limits are 0,001 % (m/m) for free glycerol, 0,10 % (m/m) for all glycerides (mono-, di- and tri-). This method is suitable for FAME prepared from rapeseed, sunflower, soybean, pa...

This part of ISO 16140 specifies the general principle and the technical protocol for the validation of alternative, mostly proprietary, confirmation methods in the field of microbiological analysis of food, animal feed, and environmental and primary production stage samples. This procedure is limited to the validation of alternative (proprietary) confirmation methods that are intended to replace (partly or completely) the confirmatory procedure described in the standard method for the enumerati...view more

This International Standard gives requirements and guidance for the estimation and expression of measurement
uncertainty (MU) associated with quantitative results in microbiology of the food chain.
It is applicable to the quantitative analysis
 of products intended for human consumption or the feeding of animals, and
 of environmental samples in the area of food production and food handling,
 of samples at the stage of primary production.
The quantitative analysis is typically carried o...

This document describes a method for the determination of organomercury in seafood/fishery products by elemental mercury analysis. The method has been successfully valideted in an interlaboratory study with a working range from 0,013 mg/kg to 5,12 mg/kg (HORRAT values <2) in seafood/fishery products [1], [2]. The limit of quantification is approximately 0,010 mg/kg organomercury (referring to dry weight, expressed as mercury) [3], [4].
Organic species of mercury, other than monomethylmercury, a...

This Standard specifies performance criteria for immunochemical methods for the detection and/or quantification of a specific protein or protein(s) of interest [POI(s)] in a specified matrix. The methods discussed are applicable to the analysis of proteins from a variety of sample types. Some uses for these methods include, but are not limited to, analysing proteins involved in crop and food production, food processing, food marketing, food safety, biotechnology or disease indexing.
