Saopštenje za medije povodom Svetskog dana metrologije
Povodom obeležavanja Svetskog dana metrologije – 20. maja, Direkcija za mere i dragocene metale skreće pažnju javnosti na važnost merenja u svakodnevnom životu, privredi, nauci i zaštiti zdravlja i životne sredine.
Ovaj datum se dugi niz godna tradicionalno obeležava u stručnoj zajednici u znak sećanja na potpisivanje Metarske konvencije 1875. godine, a počev od 2024. godine na osnovu odluke UNESCO-a i kao međunarodno priznat Svetski dan metrologije.
Obeležavanjem Svetskog dana metrologije ove godine obeležava se 150 godina od potpisivanja Metarske konvencije i osnivanja Međunarodnog biroa za tegove i mere (BIPM) i tim povodom u Parizu, u sedištu UNESCO-a okupiće se stalne delegacije pri UNESCO-u, predstavnici zemalja članica i pridruženih članova BIPM-a, predstavnici međunarodnih organizacija, naučnici, studenti i šira javnost, ističući 150 godina metrologije i jedinstvenu međunarodnu saradnju u okviru Metarske konvencije.
Merenje je fundamentalno za svaki aspekt našeg života – od trgovine, preko praćenja našeg zdravlja, do posmatranja i razumevanja sveta oko nas. Prvobitni potpisnici Metarske konvencije su to razumeli i imali su jasnu i ambicioznu viziju: da ujedine i poboljšaju sisteme merenja širom sveta, uspostavljajući sistem koji bi služio „za sva vremena, za sve ljude“. Od svog osnivanja 1875. godine, BIPM se bavio značajnim tehnološkim izazovima kako bi proizveo stabilne i tačne etalone koji bi bili pogodni za upotrebu širom sveta.
„Metarska konvencija i rad BIPM-a omogućili su svetu zajednički jezik merenja. Danas, više nego ikada, precizna merenja čine osnovu za napredak nauke, privrede, medicine, bezbednosti i svakodnevnog života građana. Ponosni smo što Srbija u kontinuitetu, još od 1879. godine kada je pristupila Metarskoj konvenciji kao Kneževina Srbija, i danas kroz rad Direkcije za mere i dragocene metale, organa državne uprave u sastavu Ministarstva privrede, doprinosi očuvanju i unapređenju globalnog mernog sistema“, istakao je direktor Direkcije za mere i dragocene metale Čedomir Belić.
Svetski dan metrologije - 20. maj 2025. godine – “Merenja za sva vremena i sve ljude“
20. maj je Svetski dan metrologije, koji se obeležava povodom godišnjice potpisivanja Konvencije o metru u Parizu 1875. godine. Ovaj sporazum pruža osnovu za svetski koherentan sistem merenja kao temelja naučnih otkrića i inovacija, industrijske proizvodnje, međunarodne trgovine, kao i poboljšanja kvaliteta života i zaštite globalne životne sredine.
Tema Svetskog dana metrologije 2025. godine „Merenja za sva vremena i sve ljude” izabrana je da bi se istakao značaj merenja u oblikovanju naše prošlosti, sadašnjosti i budućnosti. Ova tema je dobila na značaju 2025. godine, zbog obeležavanja 150. godišnjice potpisivanja Konvencije o metru.
Kao znak obeležavanja ovog značajnog jubileja, Svetski dan metrologije 2025. godine biće u središtu događaja kojima će se proslaviti vek i po međunarodne saradnje u metrologiji. Od obezbeđivanja fer trgovine i unapređenja naučnih otkrića do rešavanja globalnih izazova, poput klimatskih promena i javnog zdravlja, merenja predstavljaju temelj napretka i inovacije. Ovogodišnja tema takođe naglašava inkluzivnost, prepoznajući da su pouzdana i slediva merenja od suštinskog značaja za negovanje ravnopravnosti i poboljšanje kvaliteta života svih ljudi, svuda u svetu.
Širom sveta, nacionalne metrološke laboratorije kontinuirano unapređuju nauku o merenju razvojem i validacijom novih tehnika merenja na neophodnom nivou sofisticiranosti. Nacionalni metrološki instituti učestvuju u poređenjima merenja koja koordinira Međunarodni biro za tegove i mere (BIPM) ili regionalne metrološke organizacije, kako bi se osigurala pouzdanost rezultata merenja širom sveta.
Međunarodna organizacija za zakonsku metrologiju (OIML) razvija međunarodne preporuke, koje imaju za cilj da usklade i harmonizuju zahteve širom sveta u mnogim oblastima. OIML takođe upravlja OIML sistemom sertifikacije (OIML-CS) koji olakšava međunarodno prihvatanje i globalnu trgovinu regulisanim mernim instrumentima.
Ovi međunarodni metrološki sistemi pružaju neophodnu garanciju i poverenje da su merenja tačna, pružajući čvrstu osnovu za globalnu trgovinu danas i pomažući nam da se pripremimo za izazove sutrašnjice.
Svetski dan metrologije odaje priznanje i poštuje doprinose pojedinaca koji rade u međuvladinim, regionalnim i nacionalnim metrološkim organizacijama i institutima tokom cele godine. U novembru 2023. godine napravljen je značajan korak kada je Generalna konferencija UNESKO-a, tokom svog 42. zasedanja, zvanično priznala obeležavanje 20. maja kao Svetskog dana metrologije. Na ovaj način istaknuta je ključna uloga metrologije u unapređenju globalne naučne saradnje, a istovremeno se otvaraju nove mogućnosti za promociju metrologije, usklađujući se sa misijom UNESKO-a da izgradi bolji svet kroz nauku i obrazovanje.
