This European standard describes the determination of NOGE components with more than two aromatic rings (the two-ring NOGE is equal to BFDGE = Bis(2-hydroxyphenyl)methane bis(2,3-epoxypropyl)ether) and at least one epoxy group as well as their derivatives containing chlorohydrin functions and having a molecular mass less than 1000 Daltons in can coatings.

ISO 8442-5:2004 specifies the sharpness and edge retention of knives which are produced for professional and domestic use in the preparation of food of all kinds, specifically those knives intended for hand use.
Powered blade instruments of any kind are excluded.
Generally these types of knife are manufactured with blades of either plain edge design or with edges incorporating particular features to enhance or optimize aspects of cutting ability.
The following two types of knife blade are suitable for the cutting test.
Type A edges: cutting edges which can be resharpened by the user and edges with a pitch greater than 1mm;Type B edges: cutting edges which are not intended to be resharpened on a steel.
Whilst these knives are predominantly manufactured with blades made from various grades of heat treated steels, the testing of knives of any construction or blade material is not precluded providing that the test criteria are met.
The principle of the testing is to reproduce a cutting action, by forward and reverse strokes, against a pack of synthetic test medium under controlled parameters.

In principle, the method is appropriate for the quantitative determination of 4-methyl-1-pentene at a minimum level of 0,005 mg/kg in all of the four food simulants. However, in the case of interferences, which have been observed for some olive oil batches, the detection limit can be compromised correspondingly.

The level of m-XDA monomer determined is expressed as milligrams of m-XDA per kilogram of food simulant in the above mentioned food simulants.
NOTE   In addition to the instability of m-XDA observed in olive oil, the test laboratory could not detect any
m-XDA peak from the olive oil work-up procedure. Based on some control checks, the assumption of the test laboratory was that the extraction from the olive oil does not work. Therefore, it is recommended that the food simulant 95 % ethanol or iso-octane be applied as substitute fatty simulants instead of olive oil.  It is believed that 95 % ethanol and iso-octane can be treated in the same way as 15 % v/v aqueous ethanol and olive oil simulant, respectively. Corresponding investigations were not possible within the project.
