This document specifies the requirements for rubber O-rings and their housing dimensions, which seal gaseous hydrogen, in high-pressure hydrogen devices for gaseous hydrogen fuelling stations, such as valves, filters, joints, breakaways and other such devices. This document is applicable to O-rings suitable for sealing hydrogen gas of up to 70 MPa nominal working pressure, in the operating temperature range of −40 °C to 65 °C.

This document contains safety requirements for the design of O-rings and their housing dimensions, compound design, and test methods for seal systems. This document applies to newly manufactured O-rings for hydrogen gas seal in high-pressure hydrogen devices used in hydrogen fuelling stations.

NOTE 1 This document was developed using the ISO 3601 series.

NOTE 2 This document was developed based on several temperature classes of rubber O-rings suitable for use with high-pressure hydrogen seals in devices for gaseous hydrogen stations.

NOTE 3 The operating temperature is not a temperature of the hydrogen gas to be sealed by the O-ring gas seal system. Regardless of the operating temperature, the hydrogen gas temperature to be sealed can rise up to 180 °C.

NOTE 4 The O-ring seal system for the high-pressure hydrogen devices are designed by the device manufacturers. The detailed specifications of the O-rings and design of static or non-static high-pressure hydrogen seal systems for the high-pressure hydrogen devices are determined as agreed upon between the interested parties by referring to this document.
