European Journal of Mineralogy is a fully open-access journal. This model ensures that all published articles are freely available to anyone with an internet connection, maximizing their visibility and impact. To cover the costs of the editorial and production processes, EJM levies Article Processing Charges (APCs).
The EJMA (Expansion Joint Manufacturers Association) Standard serves as the premier global authority for the design, application, and installation of metallic bellows expansion joints. Currently in its 11th edition, the standard provides critical technical guidelines for stress calculations (including hoop and meridional bending) and fatigue life expectancy.

The EJMA Standard serves as the primary authority for designing metallic bellows expansion joints to manage thermal expansion, vibration, and seismic activity in piping systems. The latest 11th edition shifts to an online-only format featuring updated, enhanced equations for fatigue, stress, and stability compared to the 10th edition. For more details, visit EJMA .

A proper understanding of the EJMA Standard requires familiarity with its key sections. When you open the , pay special attention to these chapters:
EJMA outlines requirements for materials, from common stainless steels to high-nickel alloys (Inconel, Incoloy) used in extreme temperature environments. It also covers the construction of accessories like ties rods, hinges, and gimbal structures, which are essential for restraining pressure thrust. European Journal of Mineralogy is a fully open-access
The EJMA Standard, particularly the 11th Edition, is the authoritative guide for the design, selection, and application of metallic bellows-type expansion joints. Covering crucial engineering calculations for pressure, thermal movements, and fatigue life, the standard ensures safety in piping networks, with current editions transitioning to a cloud-based format.

For those using the acronym "EJMA" to search for the European Journal of Mineralogy , it's worth noting that the letters 'A' and 'N' can be easily confused in acronyms. The "EJMA" abbreviation more commonly refers to the , which publishes a completely separate set of industrial engineering standards. This article, however, focuses on the academic context of the European Journal of Mineralogy . The latest 11th edition shifts to an online-only
If you are working with the PDF specifically, pay close attention to and the Examples section at the end of the document. These sections provide the practical application of the theory and are invaluable for verification during the drafting and review process.
While the full standard is a detailed document, its core content can be understood by its main technical sections:
