GB/T 12686-2017Glyphosate acid technical material (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 12686-2004 "glyphosate original drug", compared with GB/T 12686-2004, the main technical changes are as follows:

--- Formaldehyde by the mass fraction of not more than 0.8g/kg revised to not more than 1.2g/kg;

--- Nitrosylation of glyphosate by strong anion exchange method to derivatization of the reversed-phase liquid chromatography. This standard proposed by the China Petroleum and Chemical Industry Federation. This standard by the National Standardization Technical Committee of pesticides (SAC/TC133) centralized.

1 Scope

GB/T 12686-2017 is the Chinese national standard on glyphosate acid technical material, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 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 July 2018. Classification: ICS 65.100, CCS G25. 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 the original glyphosate, test methods and signs, labels, packaging, storage and acceptance period. This standard applies to glyphosate and its production of impurities in the composition of the original glyphosate.

Note. Other names, structural formulas, and basic physico-chemical parameters of glyphosate and nitroso-glyphosate are given in Appendix A.
