What is ISO 7866 about?
ISO 7866 discusses refillable seamless aluminium alloy gas cylinders. ISO 7866 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests for refillable seamless aluminium gas cylinders. The cylinders addressed in ISO 7866 have water capacities of 150 litres for compressed, liquefied and dissolved gases for worldwide use (normally up to +65 °C).
The objective of ISO 7866 is to balance design and economic efficiency against international acceptance and universal utility.
Who is ISO 7866 for?
ISO 7866 on refillable seamless aluminium alloy gas cylinders is useful for:
- The petrochemical industry
- Gas cylinder manufacturers
- Design engineers
- Research and development facilities
- Quality control personnel
Why should you use ISO 7866?
Compressed gases need to be handled and transported carefully due to their volatile nature. Containers need to adhere to the highest quality standards to mitigate risks and hazards. The purpose of ISO 7866 is to provide a specification for the design, manufacture, inspection and testing of these containers. The seamless aluminium alloy gas cylinders that are made to the specification of ISO 7866 are suitable for worldwide usage. These cylinders can hold gases at much higher pressures than ordinary atmospheric standards.
Among the many desirable properties that aluminium offers, the three most important benefits arise from its lightweight, durability and corrosion resistance. Since aluminium is lightweight, it allows more cylinders to be easily transported, as compared to other materials. ISO 7866 helps you to manufacture affordable, lightweight, durable gas cylinders.
What’s changed since the last update?
BS EN ISO 7866:2012+A1:2020 supersedes BS EN ISO 7866:2012. BS EN ISO 7866:2012+A1:2020 includes some technical changes with respect to BS EN ISO 7866:2012. These include:
- A new subclause (11.7) has been added to address unacceptable manufacturing defects and unacceptable surface features at the time of manufacture and changes have been made to other subclauses to complement the new subclause
- Terms and definitions and the symbols have been revised
- Terminology changes included: “stress” changed to “strength”
- Various editorial errors were corrected
- Equipment calibration requirements were added
