ISO 18744:2016 specifies a method that is applicable for the detection and enumeration of Cryptosporidium oocysts and Giardia cysts on or in food products that are described herein as fresh leafy green vegetables and berry fruits. With suitable controls, it may also be applicable for the examination of other fresh produce.
The microscopy descriptions are for Cryptosporidium spp. oocysts and Giardia duodenalis cysts of size ranges which include those species (Cryptosporidium) or assemblages (Giardia) known to be pathogenic to humans.
This method does not include any molecular analysis and therefore is not suitable for the determination of the species or genotypes/assemblages of Cryptosporidium oocysts and Giardia cysts. The method will detect all species and genotypes/assemblages that are known to be pathogenic for humans and also others that are not. For further identification, molecular typing assays are required. However, these cannot be reliably performed if process positive controls have been spiked into the samples, as the result of molecular typing assays will be obfuscated.
This method does not allow the determination of viability or infectivity of any Cryptosporidium oocysts and Giardia cysts which may be present.

This European Standard specifies methods for the extraction and clean-up of food samples of plant origin for quantitative determination of pesticide residues.
Different solvents can be used for this purpose. These pesticide residues are generally associated with other co-extracted compounds which would interfere in the analysis. To purify the crude extracts to be analysed, several techniques can be used.
This European Standard contains the following extraction and clean-up methods that have been subjected to interlaboratory studies and/or are adopted throughout Europe:
- method M: Extraction with acetone and liquid-liquid partition with dichloromethane/light petroleum, if necessary clean-up on Florisil® ) [1], [2], [3];
- method N: Extraction with acetone, liquid-liquid partition with dichloromethane or cyclohexane/ethyl acetate and clean-up with gel permeation and silica gel chromatography [4], [5];
- method P: Extraction with ethyl acetate, and if necessary, clean-up by gel permeation chromatography [6].
This European Standard specifies the details of methods M, N and P for the extraction and the clean-up of food samples of plant origin. Several solvents at different volumes are used for extraction. Techniques of clean-up are listed such as liquid-liquid partition, liquid chromatography on various adsorbents and gel permeation chromatography.
A table providing the couples (matrix/pesticide) which have been submitted to collaborative studies and a list of indicative applicability of the method to different pesticides are given for each method, wherever possible.

ISO 5518:2007 specifies a method for determining the benzoic acid content of fruits, vegetables and derived products.
As chlorobenzoic acids are resistant to oxidation, the method cannot be applied in the presence of p-chlorobenzoic acid, as the absorption spectrum of this acid is close to that of benzoic acid. Neither can it be used in the presence of cinnamic acid, which is transformed into benzoic acid by chromic acid oxidation.

This method is particularly applicable to thick products, to products containing suspended matter, and to products rich in sugar. If the products contain other dissolved substances, the results will be only approximate; nevertheless, for convenience the result obtained by this method can be considered conventionally as the soluble solids content.

ISO 17240:2004 specifies an atomic absorption spectrometric method for the determination of the tin content of fruit and vegetable products in the concentration range 10 mg/kg to 500 mg/kg. It is a rapid method, especially suitable for routine determinations of tin in canned fruits and vegetables contaminated with tin which has migrated from the can. The method can be applied with the prescribed amount of sample to products with a maximum total dry matter content of 30 %. Products with higher contents of total solids can be analysed using smaller amounts of sample after corresponding dilution with deionized water.

The determination of free sulphur dioxide consists in direkt iodometric titration of the product at a pH between 0,7 and 1, followed by blank titration of the product, freed from sulphur dioxide by boiling under reflux or by binding its free sulphur dioxide content with an exess of acetaldehyde or propioaldehyde. The bond sulphur dioxide is determined after titration of free compound, rendering of the produkt alkaline and titration of the sulphur dioxideliberated by hydrolysis with iodine in an acid medium.
