Special Tests of Long Length Standards
The Dimensional Metrology Group (683.01) provides special tests on a fee for service basis of long length standards upon customer request. The group performs a feasibility study of all requests to determine if we can provide an appropriate calibration.
In the past, the Dimensional Metrology Group has provided special tests and length calibrations for fiber optic cables standards over 1 km in length, for special 5 m length rods used in the nuclear power industry, and for ball bars up to 3 meters in length.
Uncertainties for special tests are dependent on the type of calibration performed and are computed on a case by case basis. To discuss special tests please call the Dimensional Metrology Group contact listed.
