DIN EN ISO 2171:2010-08

This International Standard specifies a method for determining the ash yielded by cereals, pulses and their milled products intended for human consumption. These cereal products include the following: a) grains of cereals; b) flours and semolinas; c) milled products (bran and high bran content products, coarse bran flour); d) mixed cereal flours (flour mixes); e) cereal by-products other than milled products; and f) pulses and their by-products. A test portion is incinerated until combustion of organic matter is complete, then the residue obtained is weighed. The residue obtained is flaky after incineration at 550 °C and vitrifies after incineration at 900 °C. In general, products containing salts (for instance, sodium chloride, diphosphate) shall be incinerated at (550 ± 10) °C. A table summarizes incineration temperatures according to product type. At DIN, the Committee responsible for this standard is NA 057-05-06 AA "Getreide und Getreideerzeugnisse" ("Cereals and cereal products").
