DUMAGUETE CITY (Dec 7, 2016) –  Close to 20 participants from sugar and coconut milling companies and planters association in the province attended the one-day training on weighing scale calibration on December 2, 2016 at the Sugar Bowl of Asociacion Agricola de Bais y Tanjay Inc. (AABT) in Bais City, Negros Oriental.

Organized by the  Department of Science and Technology-Negros Oriental Provincial S&T Center (DOST NegOr PSTC ), the  training  aims to give importance on the calibration of industrial weighing scales on various applications and the acceptability level on error readings of weighing scales in the market. Large industries are required to calibrate their weighing scales to avoid sanctions that may be imposed to them by the Department of Trade and Industry (DTI) once they will be found violating, as provided under Republic Act 7394 or the Consumer Act of the Philippines. The Act is the policy of the State to protect the interests of the consumer, promote his general welfare and to establish standards of conduct for business and industry.

The activity is in cooperation with Negros Oriental Chamber of Commerce and Industry (NOCCI), DOST 7 and DOST NIR. Engr. Roberto B. Edra, the laboratory head of DOST-7 Regional Standards and Testing Laboratory (RSTL) was the resource person during the said training.

During the quick but very informative seminar, Engr. Edra expounded on metrology, calibration, mass, measurement standards, traceability, classification of weights and calibration of weighing scales. Other topics on basic calibration principles, metrology in the Philippines, traceability, classification of balances, computations on maximum permissible errors and the relationship between mass and weight. The speaker also discussed on proper care of weights, methods of weighing, weighing errors and their causes, minimum accuracy class of weights used with weighing instrument and the International Organization of Legal Metrology (OIML).

“The starting point of International Standards begins with the Bureau International des Poids et Measures (BIPM). Its mandate is to provide the basis for a single coherent system of measurements throughout the world. It directly disseminates units and coordinates international comparisons of national measurement standards as well as performing calibrations for member national metrology institutes ,” Engr. Edra also added.

Engr. Edra is the laboratory head and quality manager of DOST 7 RSTL. He was formerly connected with DOST ITDI (Industrial Technology Development Institute) where the National Metrology Laboratory of the Philippines is located. He has been involved in numerous trainings nationwide and abroad on weighing scale calibration, among others.– Sean Adrian T. Guardiano/Negros Oriental PSTC S&T Media Service
