ISO 5119:2023

This specification details a test method for static O-ring seals in elastomeric materials which are subject to pressurized gas media at low temperatures. It gives guidance on the design of test equipment, standard test parameters, and reporting criteria. It does not specify performance criteria that should be agreed upon between supplier and customer.
The test procedure may be used to test seals of alternate size and design or using alternative media but such deviations shall be detailed separately on the report form and the results shall not be used to determine the minimum operating temperature of seals of any other configuration than that tested.
