The Caribbean Community (CARICOM) has a relatively developed system for national legislation for weighing machines. Automatic weighing devices are widely used to determine the quantity of loads in terms of mass. While some applications are specified by national legislation, they are subject to legal metrological control. In CARICOM there is an ever increasing need to have metrological quality confirmed by calibration testing systems against a standard of higher accuracy ensuring consistency in system integrity, for example, where required by ISO 9001 and ISO/IEC 17025 standards
From 22-25 February 2010, the Trinidad and Tobago Bureau of Standards (TTBS) in collaboration with CROSQ, will deliver a workshop at its PQSL Auditorium and Mass Laboratory entitled “Calibration of Weighing Machines EURAMET According to the SIM Guide, SIM WGW7/cg-01v.00”.
his workshop aims to assist calibration reference laboratories personnel and metrologists (and by extension support Member States) with the expansion of their services for the calibration of weighing machines and having their metrological quality confirmed by calibration. The workshop will be facilitated by Mr. Luis Omar Becerra and Mr. Jorge Nava, both of CENAM (Centro Nacional de Metrología), and funded is provided through the support of Trade.Com and PTB (Physikalisch-Technische Bundestalt).
According to the CROSQ Technical Officer for Metrology, Gina Teemul-Tash, the objective of the workshop is to introduce participants to the SIM guide. “The idea is to provide the participants with the necessary tools and knowledge to go back to their laboratories and implement a calibration service for weighing machines.” The Inter-american Metrology System (SIM) resulted from a broad agreement among national metrology organizations from all 34 member nations of the Organization of American States (OAS) and has adopted the guide, SIM WGW7/cg-01v.00, which will be used as a base document for the development of a calibration procedure for weighing machines, specific to the region.
The workshop is also expected to assist participants with developing a calibration procedure for weighing machines and will introduce uncertainty measurement for weighing machines. At the end of the training, participants will be able to perform calibration of weighing machines according to SIM MWG7/cg-01 v.00, calculate measurement results, determine the uncertainty of measurement for weighing machines, establish a calibration procedure for weighing machine, and design and put into operation, a data entry form and a calibration certificate for weighing machine calibration.
