ISO 10360 Requirement |
Realization by KOBA-Step |
| 1 |
Demand for an artifact |
One dimensional test standard, each gage face is arranged along
the line of measurement. |
| 2 |
Traceability to a national standard |
Can be calibrated to several national standards |
| 3 |
Two or more parallel faces |
Large number or plane parallel gage faces along the line of measurement |
| 4 |
Shortest measuring length <30mm |
Standard distance is 20mm |
| 5 |
Measuring range about 2/3 of the volumetric diagonal |
Various lengths up to 2500mm |
| 6 |
Uncertainty of measurement of the standard less than 20% of E |
Smallest possible uncertainty of measurement for calibration: U =
0.2µm + 0.5 * 10-6 * L |
| 7 |
Seven positions of the standard in the measuring volume |
Positioning guaranteed by multipurpose accessories. |
| 8 |
Minimum of five measuring lengths in every position |
Guaranteed by division of 20mm, even at smallest nominal length |
| 9 |
Evaluation of the measuring results |
Simple, manual evaluation or optional software (according to VDO 2617) |
| 10 |
Stability of the test standard |
Stable "U" shaped cross section, the line of measurement is
situated on the neutral fiber of the body. |
| 11 |

Coefficient of thermal expansion is known: (11.3 * 10-6
°K-1 |
| 12 |
Long term stability |
No structural changes; very high mechanical strength |
| 13 |
Simple geometric probing elements |
Flat and parallel measuring faces along the measuring line |
| 14 |
Equal distribution of the probing elements over the length |
Constant steps over the measuring length |
