How do I create a calibration certificate?

Calibration certificate iso 17025

If you have read any of my posts you will know that from this corner I want first of all to let you know in a simple way situations that you may encounter on a daily basis while implementing ISO 9001:2015 in your organization. Today I am going to focus on one of the key requirements of the standard and explain when you should perform calibration and verification on your equipment to comply with ISO 9001.

As you have started reading this post, maybe it is because you are a little lost regarding the internal verification that you must perform on the measuring equipment that your company has, or because you are not very clear about the difference between verification and calibration, or maybe because you do not understand very well what the standard requires in this requirement “7.1.5 Monitoring and Measurement Resources”.

If you go to the VIM (International Vocabulary of Metrology), you will see that it defines calibration as [I copy literally] “an operation that under specified conditions establishes, in a first stage, a relationship between the values and their associated measurement uncertainties obtained from measurement standards, and the corresponding indications with their associated uncertainties and, in a second stage, uses this information to establish a relationship to obtain a measurement result from an indication.”

What a calibration certificate must have

A calibration certificate is a physical or digital document that contains the results of the calibration of an instrument, such as a balance or thermometer. The product of a calibration is the relationship between the readings of an instrument and the values indicated by a standard. It is possible that these instruments, once calibrated, may be used to measure other instruments, in which case the instruments compared will themselves serve as standards.

Although a calibration certificate does not necessarily include verification of compliance with a regulatory requirement, issuers often include verification results with respect to standards, regulations or specifications.

a. Corrections. The main benefit for a user is to use the information corresponding to the measurement error of the instrument readings, in relation to the standard, in order to correct them or to correct the production process in which the instrument is used, and to ensure its traceability with an appropriate uncertainty. If this information is not used, the cost of calibration becomes a waste. When it is not practical to correct each reading with the calibration results, it is advisable to increase the uncertainty of the measurements accordingly.

It is important to understand that traceability is the property of the result of a measurement. Having a current calibration certificate, an elaborated traceability letter, having the calibration certificates of the standards, copies of the laboratory’s accreditations and any other documents you can think of does not guarantee the traceability of the measurement or that the measurements are accurate or representative.

The accreditation scheme for laboratories involved in different links in the measurement chain is intended to alleviate the task of analysis, leaving it to a technical group of experts as part of the accreditation process.

If you have a calibration performed by an accredited calibration laboratory you can be confident that your calibrated instrument does have the required traceability, because this point is meticulously reviewed during the laboratory accreditation audit by the group of impartial experts.
