ICS 71.100.20 CCSG86 National Standards of the People's Republic of China Replaces GB/T 5829-2006 Pure spender, high pure spender, and super pure spender Published on 2025-08-29 Implemented on 2026-03-01 State Administration for Market Regulation The State Administration for Standardization issued a statement.

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 5829-2006 "Krypton". Compared with GB/T 5829-2006, apart from structural adjustments and editorial changes, the main differences are as follows. The technological changes are as follows. ---Content related to the properties, molecular formula, molecular weight, and uses of krypton has been removed from the scope; content related to ammonia synthesis tail gas and nuclear reactors has been added. Methods for preparing krypton from fission gas (see Chapter 1, Chapter 1 of the.2006 edition); ---Technical requirements for krypton gas with 99.9995% and 99.9999% purity have been added, requirements for total impurity content have been increased, and some impurity requirements have been modified. Limits for mineral content (see Chapter 4, Chapter 3 of the.2006 edition); ---The safety requirements for krypton sampling have been changed (see Chapter 5, 4.1.2 of the.2006 edition); ---The method for calculating krypton purity has been changed (see 6.1, 4.2 in the.2006 version); ---The rules for verifying kryptonite have been changed, and provisions for numerical rounding have been added (see Chapter 7, 4.1 of the.2006 edition); ---The methods for determining the carbon monoxide, carbon dioxide, and methane content in krypton gas have been modified, replacing them with helium ionization gas chromatography. Replace flame ionization gas chromatography (see 6.2, 4.5 of the.2006 edition); ---The method for determining the hydrogen content in krypton was changed, replacing gas-sensitive chromatography with helium ionization gas chromatography (see 6.2,.2006). (4.4 of the.2018 edition) ---The method for determining moisture content has been changed, and equivalent methods specified in GB/T 5832.3 and GB/T 5832.4 have been added to address different... The purity of krypton specifies the corresponding arbitration method (see 6.3, 4.6 of the.2006 edition); ---Requirements for exhaust gas treatment have been added (see 6.4); ---Added labeling requirements (see 8.2); ---Added requirements for accompanying documents (see 8.3); ---Regulations regarding packaging, filling, transportation, and storage have been amended (see Chapter 9, Chapter 5 of the.2006 edition); ---Added security information regarding Krypton (see Chapter 10).

The release history of this document and the document it replaces is as follows. ---First published in 1986 as GB/T 5829-1986 "Pure Krypton"; ---First revised in.1995 as GB/T 5829-1995 "Krypton", and incorporated into GB/T 5830-1986 "Testing of Pure Krypton and Pure Xenon". The content of the "Methods" (GB/T 5830-1986 was the first publication); ---Revised for the second time in.2006 as GB/T 5829-2006 "Krypton"; ---This is the third revision. Pure spender, high pure spender, and super pure spender 1.Scope This document specifies the technical requirements, sampling, inspection rules, marking, labeling, accompanying documents, packaging, and filling procedures for pure krypton, high-purity krypton, and ultra-pure krypton. The requirements for packaging, transportation, and storage are described, relevant test methods are explained, and safety information for krypton is provided. This document applies to the separation and purification of gases from air, ammonia synthesis tail gas, or nuclear reactor fission gas using cryogenic methods. Pure pay-to-win, high-pure pay-to-win, and super-pure pay-to-win.
