Supplementary comparison EURAMET.L-S26.1: Measurement of groove depth standards in the range 1 µm up to 1 mm. Follow-up of EURAMET.L-S26
Project Description
The depth of six v-shaped grooves with nominal values 5/20/50/200/600 and 900 µm have to be measured. The depth has to be measured according to ISO 5436-1. The PTB nickel depth setting standard is used as reference standard. PTB measures all depths, MIKES 3 smaller depths and UME 3 larger depths.
This Supplementary Comparison is a follow-up of the EURAMET project 1407: Measurement of groove depth standards in the range 1 µm up to 1 mm.
Final Report 2023-03-31
The comparison has been completed and results are published in the KCBD.
Progress Report 2022-06-20
The measurements have been performed and Draft A distributed. Next, Draft B will be prepared.
CEM (Spain) joins the comparison as a further participant.
