Maize - Determination of moisture content (on milled grains and on whole grains)
 N EN ISO 6540

Annotation

Introduction

The basic reference method and the routine reference method relating to cereals (ISO 711 and ISO 712) are only applicable to maize with a number of amendments. This is why is has been considered advisable to reproduce the whole of these two methods, amended for application to the case of maize.

The basic reference method, for maize, which is called the absolute method in this case, requires special equipment and experienced personnel, and can only be applied in specialized laboratories.

Because of the vary 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 grains, the determination of the moisture in maize raises problems with regard to its pre-drying and grinding.

Consequently, to allow the pre-drying and grinding to be avoided, this International Standard also describes a routine method for whole grain which is easier to use and allows working in series.

Введение

Основной справочный метод и обычный справочный метод, касающийся круп (ISO 711 и ISO 712), только применимы к кукурузе со многими поправками. Это - то, почему, считался желательным для репродуцирования всех этих двух методов, исправленных для применения к случаю кукурузы.
