ISO 12099:2017给出了通过近红外光谱测定诸如水分，脂肪，蛋白质，淀粉和粗纤维等成分以及动物饲料，谷物和碾米产品中的消化率等参数的指导。 该测定基于近红外光谱区域的光谱测量。

ISO 12099:2017 gives guidelines for the determination by near infrared spectroscopy of constituents such as moisture, fat, protein, starch and crude fibre and parameters such as digestibility in animal feeding stuffs, cereals and milled cereal products. The determinations are based on spectrometric measurement in the near infrared spectral region.
