The advantages of using the same data format throughout your company are self-evident: measurement data from a variety of measurement systems can be centralized without complications, allowing for consistent data management and analysis. It is also the best way to compare company-wide results, since data need not be converted, which reduces the scope for errors. This is even more effective when the measurement system manufacturer has had the Q DAS data format certified. Thanks to the successful use of this data format, a number of large companies have decided to insist on the mandatory use of this format when ordering new measurement systems.
The data format became established as a "quasi-standard" in the industry many years ago. About 20 years ago, industry representatives formed a working group that made a certain part of the format mandatory. The idea of the working group and the standardisation of SPC data transfer was taken up by the standards and since 2023 the basic format of the Q-DAS ASCII transfer format has been mandatory in ISO/TR 11462-5:2023.

Advanced Quality Data Exchange Format AQDEF
The AQDEF (Advanced Quality Data Exchange Format) working group was founded to specify a standardized data exchange format, binding requirements for data acquisition and data transfer between measurement system manufacturers and Q-DAS software products. It is the goal of the working group to reduce the effort for both measurement system manufacturers and end-customers by combining the requirements of multiple specifications for interfaces and data formats into one. The work group is open for any questions and proposals. The representatives of the Q-DAS company will suggest them to the work group. Please make your enquiries in English or German, if possible.
The local contacts will forward their enquiry to the 2 members of the working group (Uwe Brang and Thomas Gastgeb).
