The term laboratory is generally associated with organizations of high technical and scientific level equipped with advanced technical means and highly qualified personnel, but unfortunately the reality is not necessarily that.
The reality is that among the companies that provide testing or calibration services are those that, in effect, have shown that this idea that is generally had of a laboratory is true and others that have not.
The former have an ENAC accreditation. The second, no.
For this reason, when a company considers contracting testing or calibration services, if it wants to have the maximum guarantees of technical competence without running risks, it must opt for accredited laboratories, because they have proven to have the necessary technical solvency while in the case of unaccredited laboratories, you only have personal confidence in the laboratory’s own statements.
