At a constituting assembly on March 5, 1873 in Offenbach, the “Association for the Revision and Monitoring of Steam Boilers with Central Office in Offenbach am Main” is founded. The association has 131 members with 211 steam boilers. The first revision is performed on July 28, 1873 by the engineer A. Arnoldi.
Founding of the Steam Boiler Monitoring Association in Kassel
The association founded in Offenbach in 1873 is renamed “Dampfkessel-Überwachungs-Verein mit Sitz in Offenbach am Main” (Steam Boiler Monitoring Association with Central Office in Offenbach am Main).
In Germany, the general technological development leads to the monitoring of other installations requiring monitoring by the steam boiler monitoring associations. (In 1905, e.g., the Cost Law lists installations requiring monitoring, such as elevators and motor vehicles, steam barrels, and containers for gases, mineral water machines, and acetylene and power plants.)
