This International Standard specifies a method for determining the ash yielded by cereals, pulses and their milled products intended for human consumption. The source materials covered are: grains of cereals; flours and semolinas; milled products (bran and high bran content products, sharps); mixed cereal flours (mixes); cereal by-products other than milled products; and pulses and their by-products. This International Standard is not applicable to starches and starch derivatives (see ISO 3593), to products intended for animal feeding stuffs (see ISO 5984), or to seeds.
