Abstract
Overview
ISO 6654:1991 specifies a spectrometric method for the determination of in animal feeding stuffs. The standard defines the urea content, references sample preparation according to , and describes the principle, reagents, apparatus, sampling, test-sample preparation, procedure, result expression and test reporting. The method uses a color‑developing reagent and spectrometric measurement to quantify urea for quality control and regulatory verification.
