Measure according to standards
If they’re going to serve the general public, standards must be based on proven results from science and technology. That's why Fischer also contributes its expertise in metrology to a host of standardization bodies.
In November 2017, Fischer collaborated in publication of the DIN 50994 standard, which, for the first time, regulates the use of the phase-sensitive eddy current method to measure the conductivity of metallic layers non-destructively. In addition to the methodology thereof, the standard also describes typical fields of application.
Conductivity is more than just an electrical property of a given material: It provides information about a substance’s hardness, the structural stability of alloys and layer stresses. Even heat damage and material fatigue can be determined via this method.
The Fischer SIGMASCOPE® SMP350 can be used for all these diverse applications. With the three probes of the FS40 series, you can always measure in compliance with standards, despite different penetration depths and sample geometries.
Currently, DIN 50994 is only obligatory in Germany. However, since there is no international counterpart, it’s being tested by the International Organization for Standardization as an ISO standard.
