---GB/T 22141-2008. General requirements for mixed feed additive acidifiers

1 Scope

GB/T 22141-2018 is the Chinese national standard on general rules for acidifiers as mixed feed additive, 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 17 September 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 April 2019.

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 terms and definitions, technical requirements, sampling, test methods, inspection rules, labels, and additives for mixed feed additive acidifiers. Packaging, transportation, storage and shelf life. This standard is applicable to mixed feed additive acidifiers, and for the production enterprises to develop mixed feed additive acidifier product standards For guidance.
