Maize - Determination of moisture content (on milled grains and on whole grains) (ISO 6540:1980); German version EN ISO 6540:2010

Title (German)

Mais - Bestimmung des Feuchtegehalts (von gemahlenen und ganzen Körnern) (ISO 6540:1980); Deutsche Fassung EN ISO 6540:2010


The basic reference method and the routine reference method relating to cereals (ISO 711 and ISO 712) are only conditionally applicable to maize. This is why it has been considered advisable to revise the two methods through a number of amendments, so that they can be applied to maize. The reference method for maize which is called the absolute method in this case, requires special equipment which is only available in certain laboratories, and personnel with the appropriate experience. Because of the very high moisture content which may be present in samples of maize [sometimes greater than 40 % (m/m)] and because of the size and texture of the maize grains, the determination of the moisture raises problems with regards to pre-drying and grinding. As a result, the current standard describes a routine method next to the absolute method which avoids the pre-drying and grinding, making it easier to use and applicable for serial determination. The Committee responsible for this standard is NA 057-05-06 AA "Getreide und Getreideerzeugnisse" ("Cereals and cereal products") at DIN.
