In this case, the weighing instruments must be calibrated on a periodic basis that is established by the company in agreement with the Quality Inspector, also depending on the intended use.
If the instrument plays a fundamental role in the company production process and the frequency of its use is high, the checks can be monthly or half-yearly.
If, on the other hand, the instrument is used for marginal activities and with low frequency, the checks may be more extended over time, for example every 24 - 36 months.
The verification is carried out using calibrated sample weights, referable to national or international samples.
LAUMAS has a worldwide network of service centres capable of carrying out calibration reports that can be used in an ISO 9001 system.
