The Department of Science and Technology VII recently held a seminar on metrology to enhance public awareness of modern weight calibration processes consistent with the international standards of weight measurement.
The DOST-sponsored seminar was conducted by Hintendra Bisht, metrology consultant and trainor, and held at the DOST VII S&T Complex in Cebu City last May 23, 2017.
Metrology is the science of measurement. It is useful in gaining quantitative information of a physical object through measurement of its physical quantity or property according to specific measuring standards.
As the seminar had zeroed in on mass metrology, the lecture centered on modern calibration processes and practices that ensure calibration tools and measuring instruments perform at levels of accuracy traceable to international standards.
Calibration is “process of configuring an instrument to provide a result for a sample within an acceptable range”. It also helps in “eliminating or minimizing factors that cause inaccurate measurements.”
The seminar participants were taught about importance of mass calibration and the proper and efficient way to conduct modern calibration job.
Conformity and universality in measurement standards and practice is of vital importance to people’s lives. The costs of human consumption, as well as the prices of goods sold to consumers, for example, are determined based on standards of measurement.
Diversity in measurement standards and discrepancies in measurement results could lead to dire consequences in terms of economic loss and even loss of lives and property.
Roberto Edra, chief of the DOST VII Regional Science and Technology Laboratory (RSTL), and who heads the agency’s calibration team, stresses the need to ensure reliable reference of mass standards by the use of efficient calibration instruments that are traceable to the standards set by the DOST-Industrial Technology Development Institute (ITDI).
He thus encourages the public who use measuring instruments in their business or professions to have them properly calibrated. Calibration of these instruments is one of the services provided by the RSTL.
Edra cited Presidential Decree No. 231, otherwise known as the Local Tax Code of 1973, which requires local governments to “keep full sets of secondary standards in their office for use in testing of weights and measures. These secondary standards shall be compared with the fundamental standards in ITDI at least once a year”.
He further explained that this is necessary for the people to have measuring instruments with levels of accuracy that are in harmony with national or international standards and best practices.
