Intercomparison of Measurements on Surface Texture Standards

Project Description

Comparison on surface texture calibration using the profile method on 4 roughness standards:

- type A1 (groove depth)
- type C (x2)
- type D1 (random)

as described in ISO 5436-1.

The parameters which could be measured:

- amplitude parameters (peak and valley) : Rp, Rv, Rz, Rt (ISO 4287)
- amplitude parameters (average of ordinates) : Ra, Rq, Rsk, Rku (ISO 4287),
- spacing parameters: RSm (ISO 4287)
- depth: d (ISO 4287)

Standards:
- Type A1 : Rupert type 511 - RS1 (2 grooves, d = 1 µm, Width = 100 µm)

      or          DZHM standard (rectangular groove and profile) Pt = 0,06 ÷ 0,1 µm)

- Type C: Rubert type 527E (Ra = 3 µm; Sm = 100 µm; Pt = 10 µm)
                Rubert type 542E (Ra = 0,06 µm; Sm = 8 µm; Pt = 0,2 µm)

- Type D1: Rubert type 503E (Ra = 0,1 µm)

Plus a comparison using 1 or 2 soft gauges.
- Type D1: Rubert type 501E


Final Report 2017-05-31

The comparison has been completed and results are published in the KCDB.
