The periodical verification on scales can be carried out only by labs certified by the Chamber of Commerce. In this field, PTM has its own internal laboratory, called PTLAB, which is able to carry out the periodical verification on weighing instruments. PTLAB is certified by the Chamber of Commerce of Brescia, and offers the calibration service on scales and dynamometers, releasing the necessary documents.


In the following, there is a brief extract from the current regulations concerning this topic:

Under the decree dated 28 march 2000, n. 182 "Regulations on the modification and integration of the discipline regarding the periodical verification of metrological instruments in commerce and chamber of commerce matter", the weighing instruments have to be periodically verified, every 3 years, in order to avoid the sanctions foreseen by the LAW DECREE 29 December 1992,n517; Art.13. Moreover, the new law has introduced the figure of labs authorized by the Chamber of Commerce, which will carry out the verification themselves, offering warranty of independence and professional technical qualifications.
