1 Scope

GB/T 1610-2024 is the Chinese national standard on chromium trioxide for industrial use, 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 71.060.20, CCS G 13. 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 requirements, test methods, inspection rules, marking, labeling and accompanying documents, packaging, transportation and Storage. This document applies to industrial chromic anhydride.

Note. This product is mainly used in the electroplating industry, and is also used as an oxidant, catalyst, wood preservative, and for the preparation of chromium trioxide, chromium chloride and other chromium salt products and reagents Raw materials.
