DIN Standards Committee Pressurized Gas Installations

Overview

Industrial, medical and special gases (for example, high-purity gases, calibration gases) can be transported or stored in gas cylinders. An essential requirement of the material from which such gas cylinders and their valves are manufactured is compatibility with the gas content. Compatibility of cylinder materials with gas content has been established over many years by practical application and experience. DIN EN ISO 11114-1 provides requirements for the selection of safe combinations of metallic cylinder and valve materials and cylinder gas content. The compatibility data given is related to single gases and to gas mixtures. Seamless metallic, welded metallic and composite gas cylinders and their valves, used to contain compressed, liquefied and dissolved gases, are considered. In this document the term "cylinder" refers to transportable pressure receptacles, which also include tubes and pressure drums. Aspects such as the quality of delivered gas product are not considered. This standard differs from DIN EN ISO 11114-1:1998-07 as follows: a) the term "not recommended" has been replaced by "not acceptable"; b) the text of the standard has been clarified; c) a requirement for gas mixtures has been introduced. The committee responsible for this standard is NA 016-00-03 AA "Druckgasflaschen und Ausrüstung; Spiegelausschuss zu CEN/TC 23 und ISO/TC 58" ("Gas cylinders and equipment; Mirror Committee of CEN/TC 23 and ISO/TC 58") at DIN.
