- Abstract:
- A national traceability in force measurement to the Regional Reference Standards Laboratory (Department of Legal Metrology) without much degradation in the uncertainty while transferring the unit from the National standards to the user is achieved by developing and commissioning a dead weight force machine of 50 kN capacity at Regional Reference Standards Laboratory (RRSL), Bangalore and 50 kN comparator type force machines at other (RRSLs located at different parts of India. The established standard machines are directly compared for their performance through an artifact calibrated against the NPL primary standard machine having a BMC of ± 0.003% (k = 2). The load cell calibration data obtained from the different machines show that the realized force is found to be within ± 0.05% and hence the performance of the established force standard machines is highly satisfactory.
