This year, the 15th D-A-CH Conference, which is organized by the Societies of Earthquake Engineering and Structural Dynamics in Germany (DGEB), Austria (OGE) and Switzerland (SGEB) took place on September 21 and 22. September.  

This gathering of experts is conducted biennially and serves both as the exchange of knowledge between seismologists and engineers and the presentation of current scientific findings and experience gained from field applications. In addition, companies operating in the fields of earthquake engineering and structural dynamics as well as manufactures of earthquake protection systems had the opportunity to present their application solutions in the foyer of the Bauhaus university.

Some weeks ago, we addressed the historical development of measurement technology. Today we would like to discuss the different measuring techniques and methods which help determine various parameters of a part being measured. Let's start with a few basic terms before we give a short overview of the most common measuring methods. 

In this blog article we are going to take a closer look at the API Standard 671 which specifies the requirements for special purpose couplings used in the petroleum, petrochemical and natural gas industries. This Standard has been developed by the American Petroleum Institute (API), which is not to be confused with the identical abbreviation used in the IT field (Application Programming Interface). Let's begin with a few details about the institute that gave the name to the API Standard.
