This document specifies a method for determining the ash yield by cereals, pulses and their milled products intended for human consumption. The source materials and products covered are: a) grains of cereals; b) flours and semolinas; c) other milling products (bran and high bran content products, shorts); d) mixed cereal flours (mixes); e) cereal by-products other than c) (such as wheat gluten, maize grits, broken rice kernels); f) pulses and their by-products (flour). This document does not apply to starches and starch derivatives (see ISO 3593), to products intended for animal feeding stuffs (see ISO 5984) or to seeds.<\/p>\n
