ISO 9622 | IDF 141:2013通过测量中红外辐射的吸收，给出了牛奶和液态奶产品（如生牛奶、加工牛奶、奶油和乳清）的定量成分分析指南。 额外的内置仪器功能，如电导率传感器，可以提高测定成分参数的性能，并允许估计其他参数。规定的指南适用于牛奶的分析。本指南也适用于其他物种（山羊、母羊、水牛等）的牛奶和衍生液态奶产品的分析，前提是对每种应用进行了充分的校准，并制定了充分的控制程序。

ISO 9622|IDF 141:2013 gives guidelines for the quantitative compositional analysis of milk and liquid milk products, such as raw milk, processed milk, cream and whey, by measurement of the absorption of mid-infrared radiation. Additional built-in instrument features, such as a conductivity sensor, can improve the performance in the determination of compositional parameters and allow for the estimation of other parameters. The guidelines specified are applicable to the analysis of cow's milk. The guidelines are also applicable to the analysis of milk of other species (goat, ewe, buffalo, etc.) and derived liquid milk products, provided adequate calibrations are generated for each application and adequate control procedures are in place.
