The first article in this context discusses how new technologies, trends and developments are reflected in existing standards and standardisation projects. Topics such as digitisation, automation and operability play a key role here. While not everything that happens in the field of digitisation and automation can be set down in standards, it is quite possible to create a basis for interoperability. The article provides an overview of how the mining industry handles this issue. The rugged operating conditions encountered in the mining industry means that plant and machinery are often exposed to high levels of wear. The high costs that usually result can be kept to a minimum by\u00a0 &#8230; <a href=\"https:\/\/2025.mining-report.de\/english\/current-issue-5-2021\/\" class=\"shortc-button small white\">Read more<\/a>\n<p>With my best regards \/\/ Mit freundlichem Gl\u00fcckauf<br \/>\nDipl.-Ing.

Wear behaviour depends on the properties of the material in question, including its strength and hardness levels, as well as on the characteristics of the opposing body and ambient medium and on the design and structural constraints.
