A: CGA V-9 (Compressed Gas Association) is the North American equivalent. If you operate globally, you need both. ISO 25760 is the international standard.
Formally titled Gas cylinders — Operational procedures for the safe removal of valves from gas cylinders , this technical standard was prepared by the International Organization for Standardization (ISO) Technical Committee ISO/TC 58 (Subcommittee SC 4) . It establishes critical protocols to mitigate the severe safety risks associated with pressurized gas releases, fragment projection, and hazardous atmospheric exposure during cylinder maintenance.
Many professionals confuse ISO 25760 with related standards. Here is a quick comparison: iso 25760 pdf
. It is primarily intended for suppliers, testing facility operators, and maintenance personnel authorized to devalve cylinders. ISO - International Organization for Standardization Key Scope & Contents Safety Focus
Operators must perform a detailed risk assessment before any devalving activity. This includes verifying the cylinder’s contents and ensuring the work area is equipped with adequate ventilation and safety shields. A: CGA V-9 (Compressed Gas Association) is the
This international standard specifies the requirements for the marking and labeling of gas cylinders, helping to prevent accidents and ensure compliance across global supply chains.
In the industrial and medical sectors, gas cylinders are indispensable tools for the storage and transport of pressurized gases. However, the lifecycle of these cylinders involves critical maintenance phases that pose significant risks to personnel. One of the most hazardous operations is the removal of the valve, a process known as de-valving. To address these risks, the International Organization for Standardization developed ISO 25760:2009 Formally titled Gas cylinders — Operational procedures for
A significant portion of the standard addresses —those that are blocked by corrosion or damaged internally, making it impossible to vent gas normally. ISO 25760 outlines several methods for safe depressurization in these scenarios:
To maintain compliance, your valve removal procedure must cross-reference ISO 25760 with local OSH (Occupational Safety and Health) regulations.
