Scope: The subject of this standard is the description of a method for the determination of the moisture content of maize in whole kernels. In view of the very high moisture content exhibited by samples of maize (in some cases over 40 %) and because of the size and structure of the kernels, there are certain problems associated with predrying and grinding when determining the moisture content of maize. Therefore both the basic reference method and the practical method for ground kernels which are described in ICC Standards No. 109/1 and No. 110/1 can only be used by special laboratories. Whole kernels are used for the method described here, which eliminates predrying and grinding. The method is easier to use and permits testing to be carried out in series. Under no circumstances can the standard be used for the adjustment or checking of instruments for moisture determination.
