1 Scope

GB/T 1288-2024 is the Chinese national standard on chemical reagent - potassium sodium tartrate tetrahydrate, in the field of chemical technology. 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 September 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 April 2025. Classification: ICS 71.040.30, CCS G 63. 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 document specifies the properties, technical requirements, test methods and inspection rules of the chemical reagent potassium sodium tartrate tetrahydrate (potassium sodium tartrate). and packaging and logo. This document applies to the inspection of the chemical reagent potassium sodium tartrate tetrahydrate (potassium sodium tartrate).

Note. The molecular formula of chemical reagent potassium sodium tartrate tetrahydrate (potassium sodium tartrate) is C4H4O6KNa·4H2O, and the relative molecular mass is 282.22 (according to 2022 International relative atomic mass), CAS number is 6381595, the structural formula is.
