1 Scope

GB 34470-2017 is the Chinese national standard on feed additive-potassium dihydrogen phosphate, in the field of agriculture. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 14 October 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2018. Classification: ICS 65.120, CCS B46. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the requirements of feed additive potassium dihydrogen phosphate, test methods, inspection rules, labeling, packaging, transportation, storage and insurance Quality of life. This standard applies to the thermal method of phosphoric acid and wet method of production of phosphoric acid feed additive potassium dihydrogen phosphate. Molecular formula. KH2PO4.
