Hi,
This is my first post into the forum, so please forgive me if I dont understand the system yet.
As a supplier of materials testing equipment we are constantly looking for ways to improve the traceability of test data especially when it is produced by computer.
Testing machines are typically made up of a integrated system of individual components (load cells, extensometers) etc. connected maybe to a electronic machine controller or to interface cards directly in the PC.
All of these items can be successfully calibrated individually by the manufacturer or third party accredited companies to ASTM or EN standards, but after all this is done, the test results from the total system could still be incorrect for many reasons (poor load frame stiffness, insufficient data sampling rate, poor data channel synchronisation, poor algorithms, drive systems inaccuracy, operator error in keying data in, lack of understanding of the limitations of the equipment and how they relate to the testing application etc.).
My questions are:
1) Is this a real-life situation as described above, and how serious is it?
1) How is all of this addressed an organisation's quality system?
2)How can equipment manufacturers help to improve the situation?
thanks in advance
David
