The ISO 407 standard, developed by the International Standards Organization (ISO), describes the basic safety and performance characteristics and test methods of pin-encrypted yoke-type valve connections of small portable gas cylinders for gases used in medical activities. This standard has been published in our country by the Turkish Standards Institute (TSE) with the following title: TS EN ISO 407 Small gas cylinders - Portable - For gases used in medicine, pin-encoded yoke type valve connections.
This standard explains the requirements with pin index yoke type valve connections for small medical gas cylinders with the highest working pressure (15 degree filling pressure) 200 bar. This type of connection is typically suitable for small cylinders of 5 liters or less. In these cylinders, attention should be paid to the need for valve protection.
This standard mainly focuses on the following points: basic dimensions, requirements for alternative designs of yoke-type valve connections, dimensions and locations for holes and pins for outlet connections. It also includes size and location requirements for holes and pins for outlet connections for certain gases and gas mixtures.
The ISO 407 standard applies to small medical gas cylinders used for patient care in hospitals and emergency departments, including treatment, diagnosis, and prophylactic applications .
The main standard referred to as normative in the application of this standard is: ISO 32 Gas cylinders for medical use - Marking for content identification.
Our organization also provides basic safety and performance testing services for pin-encrypted yoke type valve connections of small portable gas cylinders for gases used in ISO 407 medical activities within the scope of laboratory services.
