Verification of scales - non automatic weighing instruments

Non-automatic weighing instruments range from precision balances, used in laboratories to measure a few grams, to weighbridges that can measure several tons (for weighing trucks, for example). Weighing instruments are present everywhere in our daily lives: how else could we weigh our vegetables in the supermarket?
An inspection of these instruments makes it possible to limit the :

Safety risk: not having a device that indicates the right value can lead to changes in the manufacturing process or to accidents if the pressure levels are too high.
Economic risk: making a measurement error can lead to cost errors with strong repercussions.

Like any measuring instrument, weighing instruments must be checked at regular intervals to ensure that their measurements remain reliable and correct.

What is

verification of non-automatic weighing instruments?

The verification of non-automatic weighing instruments (scales) is established in Order ICT/155/2020, of February 7, as amended by Order ITU/1475/2024, of December 17, regulating the State metrological control of non-automatic weighing instruments, in their verification, after repair or modification and periodic verification phases.The State metrological control of non-automatic weighing instruments, in its phases of verification, after repair or modification and periodic verification.

Which are the equipment to be verified?

Those scales or non-automatic weighing instruments that are used to establish the mass of a body for the following purposes:

Carrying out commercial transactions
Calculation of fees, tariffs, taxes, premiums, fines, remunerations, indemnities and other similar types of charges
Enforcement of rules or regulations, as well as the performance of judicial expert opinions
Weighing of patients for control, diagnostic and medical treatment purposes.

Determination of the price or total amount in the direct sale to the public and the preparation of pre-packages.

Whether the result of the verification is positive or negative, the scale will carry in a visible place an adhesive label declaring compliance with the established requirements or a label of disqualification for service.

Apave has ENAC accreditation No. 6/EI653 to perform periodic verification and after repair or modification of weighing or automatic weighing instruments in the following categories:

Class I, 1 mg  m  600 g with n  600000.
Class I, 600 g < m  15 kg with n  130000
Class II, m ≤ 150 kg with n ≤ 100000
Class III, m ≤ 300 kg with n ≤ 10000
Class IIII, m ≤ 300 kg with n ≤ 1000

The control of health risks is based, to a large extent, on the respect of temperatures, hot or cold, which limit the proliferation of potentially pathogenic micro-organisms. It is therefore essential to be able to rely on reliable measuring instruments and to check their reliability regularly.

This regulatory verification of recording instruments must be subject to metrological control to ensure that they retain their metrological characteristics.
