Validasi Software Kalibrasi Alat Ukur Tekanan Hidraulik Sesuai dengan Implementasi ISO/IEC 17025:2017

Calibration software has a significant contribution in input data process from the calibration worksheet, analysis, until calibration certificate issues,hence it needs to be validated according to the ISO/IEC 17025:2017 clause 7.11 about Control of Data and information management. In this study, hydraulic pressure measuring device calibration software validation process has been performed by using the calibration data of the pressure monitor PPCH-200M and the parameter of standard Pressure Balance DHI PG7302 S/N 1072 in pressure range of 10% (20 MPa), 50% (100 MPa), and 100% (200 MPa)to evaluate the consistency of the calculation results of pressure standard, correction, and measurement uncertainty between calibration software and validation software with the discrepancy tolerance of 1 × 10. The result shows that the relative different of pressure standard calculation are below 1x10, with the maximum discrepancies of 0.007× 10and 0.06 × 10 at the 10% pressure point (20 MPa) for the pressure standard calculation and the measurement uncertainty, respectively. Thus, it can be concluded that the hydraulic pressure measuring device calibration software of SNSU-BSN Pressure Laboratory (I.MM.3.04.1) has been validated and can be assured for its calculation results.
