EURAMET.L-K8.2020 Technical protocol

Measurand Four ISO 5436-1 standards are used: 1 type A2 (nominal values d 0.15 μm to 9.00 μm), 1 type C3 (nominal values Ra 2.3 μm, RSm 200 μm), 1 type D1 (nominal values Ra 0.5 μm, Rz 3 μm) and 1 type D2 (nominal values Ra 80 nm, Rz 450 nm).
0.15 µm to 10 µm
Parameters Surface texture parameters: d, Ra, Rq, Rz, Rt, RSm
Transfer device Four surface texture standards (ISO 5436-1 ) are used for the comparison: 1 type A2, 1 type C3, 1 type D1 and 1 type D2.
