Traceability‘ is the key when it comes to calibration.
For calibrating measuring instruments or standards, which represent special values or limits, it is necessary to link/reference them to the physical base unit(s) they are meant for (e.g. the meter m).
Calibration is the process to determine deviations from a device or standard. This may include a validation of conformity (e.g. the product specifications) and to document the results, the method of calibration, and the standards used for the calibration a certificate of calibration will be created.
Measurements are always uncertain to a defined quantity.
There are existing several statistical methods to obtain the uncertainty according to the confidence you need. Usually, the measurement of uncertainty is given with a confidence of ≈95%.
By watching to chain of calibrations, from primary standard down to working standard [see ‘traceability’], the uncertainty of measurement will rise, because every further calibration contains the uncertainties of the standards used and in addition the uncertainty of the method of the calibration. The uncertainty of measurement in fact reflects the quality grade of the calibration.
For calibration purposes, you are always looking for better standards and/or better methods to push your uncertainty of measurement stated in the calibration certificate.
For customer's purposes, it is an economic matter of requirements vs. price. In reality, the majority of customers aren't familiar with the uncertainty of measurement. This results in decisions being made mostly by predetermined standards set up in contracts or business guidelines.
Accreditations - the reliable instrument confirming competence.
Calibration laboratories may obtain accreditation by their national accreditation body, which is the DAkkS in the Federal Republic of Germany, the UKAS in the UK, and the RvA in the Netherlands for example.
An accreditation by these bodies confirms that organizations such as testing, inspection, and certification bodies can undertake their activities competently in accordance with internationally recognized standards and in line with the regulatory requirements. This establishes confidence in the important work of these independent conformity assessment bodies and their services in all sectors of the economy.
Also, accreditation ensures the international recognition of conformity assessments, contributing to free trade in Europe and around the world.
Actually, accredited calibrations had become more of interest because of contracts and guidelines between the industry and their suppliers. Especially the automotive industry demands ‘more trusted’ calibrations for their suppliers.
More and more customers seem to prefer accredited calibrations because of some kind of insecurity with proprietary calibration.
A calibration interval is the period of time established for a test instrument to be recalibrated. Mitutoyo recommends recalibrating your instruments frequently to be confident they are performing the best and most accurate way possible.

In general for new items choose a shorter interval in the beginning. When you have results over a longer duration which you can compare you can adapt the interval.
