What is an ISO calibration?

Calibration is a set of operations designed to establish the relationship (under specified conditions) between the values indicated by a measuring instrument and the corresponding known values of a measurand. Therefore, it is a quantitative comparison used to achieve accurate weighing results on balances and scales through a series of steps established by an international body—in the case of Negri, Quartino & Ferrario , the ISO (International Organization for Standardization) standards.

What does Metrological Calibration mean?

The International Vocabulary of Measurement (IVM) defines calibration as the “operation that establishes, under specified conditions, in a first stage, a relationship between the values and measurement uncertainties provided by standards and corresponding indications with associated uncertainties; in a second stage, it uses this information to establish a relationship, seeking to obtain a measurement result from an indication.”

In short, calibration is the process of comparing the values obtained by a measuring instrument with the corresponding measurement of a reference standard (or standard) traceable to the International System of Units (SI).

Furthermore, the VIM adds that "it is important not to confuse calibration with the adjustment of a measurement system, often incorrectly called 'self-calibration,' nor with a calibration verification," which is not the same thing. Calibration provides data and information about the accuracy and precision of the instrument.

The Benefits of NQF calibration

Improve your management with international recognition

At NQF, we work in accordance with ISO standards, designed to ensure consistency in management, service delivery, and product development. These standards allow us to maintain high quality standards recognized both locally and internationally.

Trust and Transparency Guaranteed

Every sample you weigh on an NQF-calibrated balance will provide you with accurate and reliable results, backed by the highest standards. Having a certified and accredited calibration provider ensures transparency and confidence in every result.

Extend the Useful Life of Your Equipment

Calibration, along with regular preventive maintenance and good operating practices, ensures that your scale remains in optimal condition, prolonging its useful life and guaranteeing the accuracy of its results.

Cost Savings

Keeping your instruments calibrated helps you make better decisions, avoids costs due to overweight, and reduces environmental impact by minimizing waste, reprocessing, and merchandise returns.

Accreditations and Certifications

Accreditations

Accredited Calibration Laboratory: NQF is the first accredited calibration laboratory in Uruguay for the MASS category, meeting the strict requirements of UNIT-ISO/IEC 17025:2017 (equivalent to ISO/IEC 17025:2017). This accreditation ensures that our calibrations are performed under the highest international quality standards.
