Full title and description

St ISO 7195-2020 — Nuclear energy — Packagings for the transport of uranium hexafluoride (UF6). This international standard specifies design descriptions, fabrication and in-service requirements for cylinders, valve protections, valves and plugs used to transport uranium hexafluoride, and aims to ensure compatibility among different users and safe transport of UF6.

Abstract

ISO 7195:2020 provides specifications for cylinders for the transport of uranium hexafluoride (UF6), describes accepted cylinder designs (but is not intended to develop new designs), sets fabrication requirements for new cylinders designed to carry 0,1 kg or more of UF6, gives fabrication requirements for procurement of new valve protections, valves and plugs, and defines requirements for cylinders and valve protections while in service. The standard’s requirements cover aspects intended to provide compatibility among users and safe operation in transport and service.

Scope

Specifies requirements and specifications for packagings (cylinders) used to transport uranium hexafluoride (UF6), including descriptions of existing cylinder designs (not a vehicle for new designs), fabrication requirements for new cylinders intended to carry 0,1 kg or more of UF6, fabrication requirements for valve protections, valves and plugs, and requirements for cylinders and valve protections in service. The scope is focused on ensuring compatibility among users and safe transport and in-service management of UF6 cylinders.

Key topics and requirements

• Specification of cylinder types and descriptions of accepted designs (design compatibility rather than new-design development).
• Fabrication requirements for procurement of new cylinders intended for 0,1 kg or more of UF6 (materials, manufacturing controls, dimensional and weld requirements).
• Requirements for procurement and fabrication of valve protections, valves and plugs (design, materials, attachment and protection criteria).
• In-service requirements for cylinders and valve protections (inspection, maintenance, marking and compatibility checks during service life).
• Requirements intended to ensure safe transport, interchangeability and user compatibility across different organizations handling UF6.

Typical use and users

Used by designers, manufacturers and procurement organizations of UF6 transport cylinders and valve components; transport and logistics organizations handling UF6; nuclear fuel producers, enrichment facilities and utilities; inspection, testing and certification bodies; and regulatory authorities overseeing safe transport and packaging of nuclear materials.

Related standards

ISO 7195:2020 succeeds earlier editions (for example ISO 7195:2005 was withdrawn) and is maintained under ISO/TC 85/SC 5. Related standards and national/adopted versions may cover detailed test methods, transport regulations for radioactive material (modal regulations), and complementary ISO or IAEA guidance on packaging and transport of radioactive materials. The ISO record indicates the 2005 edition was previously withdrawn and that amendments to the 2020 edition (e.g., an amendment issued in 2026) have been recorded in the standard lifecycle.

FAQ

Q: What is this standard?

A: ISO 7195:2020 is an international standard that specifies packaging (cylinder) requirements for the transport of uranium hexafluoride (UF6), including fabrication and in-service requirements for cylinders and associated valve protections and valves.

Q: What does it cover?

A: It covers cylinder specifications and descriptions, fabrication requirements for new cylinders (for 0,1 kg or more of UF6), fabrication requirements for valve protections/valves/plugs, and requirements for cylinders and valve protections while in service — all aimed at ensuring compatibility among users and safe transport of UF6.

Q: Who typically uses it?

A: Manufacturers and procurement teams of UF6 cylinders and valves, nuclear fuel and enrichment facilities, transport and logistics organizations handling UF6, inspection/certification bodies, and regulators concerned with packaging and transport of radioactive materials.

Q: Is it current or superseded?

A: ISO 7195:2020 is the current published edition (Edition 3, published November 2020). The ISO lifecycle record shows the previous 2005 edition was withdrawn; amendments to the 2020 edition have been recorded (notably an amendment entry shown for 2026). For the absolute latest status (including any amendments or corrigenda released after publication), consult the ISO catalogue or your national standards body.

Q: Is it part of a series?

A: It is part of ISO work under ISO/TC 85 (Nuclear energy) and SC 5 (packages and transport), and should be considered alongside other ISO and IAEA standards/regulations that govern packaging, testing and transport of radioactive materials.

Q: What are the key keywords?

A: UF6, uranium hexafluoride, cylinder, packaging for transport, valve protection, fabrication, in-service inspection, nuclear transport packaging, ISO 7195.
