Key comparison on surface roughness standards
Project Description
Calibration of surface texture standards using the profile method. The following artefacts will be circulated:
- type A1 (groove depth)
- type C (x2)
- type D1 (random)
as described in ISO 5436-1.
Parameters to be measured according to ISO 4287:
- amplitude parameters (peak and valley): Rp, Rv, Rz, Rt
- amplitude parameters (average of ordinates): Ra, Rq, Rsk, Rku
- spacing parameters: RSm
- depth: d
In addition, a gauge according to ISO 5436-2 will be included to validate the parameter calculation.
Final Report 2016-09-26
The comparison has been completed and results are published in der KCDB.
