Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB/T 12022-2014 Industrial Sulfur Hexafluoride. Compared with GB/T 12022-2014, except for the structural adjustment and editing In addition to the functional changes, the main technical changes are as follows:

--- Changed the scope (see Chapter 1, Chapter 1 of the.2014 edition);

--- Changed the technical requirements that sulfur hexafluoride should comply with (see Chapter 4, Chapter 3 of the.2014 edition);

--- Changed the sampling requirements (see Chapter 5,

4.2 of the.2014 edition);

--- Changed the requirements for "Warning" (see Chapter 6,

4.3 of the.2014 edition);

--- Changed the general provisions of the test method (see 6.1,

4.4 of the.2014 edition);

--- Changed the calculation method of sulfur hexafluoride purity (see 6.2,

5.1 of the.2014 edition);

--- Changed the determination methods for oxygen and nitrogen, carbon tetrafluoride, hexafluoroethane and octafluoropropane (see 6.3, 5.2,

5.4 of the.2014 edition);

1 Scope

GB/T 12022-2025 is the Chinese national standard on industrial sulphur hexafluoride, 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 August 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2026. Classification: ICS 71.100.20, CCS G86. 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.
