ISO 25760 is designed for gas suppliers, testing facilities, and maintenance personnel authorized to handle high-pressure cylinders. Its primary goal is to detail procedures for —the process of removing a valve—while ensuring the cylinder is made safe from residual pressure. The standard is typically applied during: Periodic inspection and testing . Cylinder cleaning or changing the type of gas service. Replacement of damaged or inoperable valves . Preparation for scrapping or permanent disposal. Key Safety Hazards Addressed
A: The official document is approximately 12-15 pages long, plus a foreword and annexes. ISO 25760:2009 - Gas cylinders — Operational procedures
The document does not cover proprietary methods used to strip valves while a cylinder remains deliberately under pressure, such as specialized Liquefied Petroleum Gas (LPG) techniques. Critical Risks Managed by ISO 25760
The standard applies to involved in the requalification, refurbishment, or disposal of transportable gas cylinders. This includes: Its primary goal is to detail procedures for
| Section | Title | Procedure Summary | | :--- | :--- | :--- | | | Identify and Segregate Cylinders | A critical first step to sort cylinders based on valve operability to prevent accidental handling issues later in the process. | | 6.2 | Standard Devaluing Procedure | The defined safe, step-by-step procedure for removing valves from cylinders where the valve functions properly and can be opened to release pressure. | | 6.3 | Procedures for Inoperable Valves | Special, risk-assessed techniques for cylinders where the valve is stuck or cannot be opened conventionally. |
The standard categorizes requirements into three main pillars:
