»Calibration! What is it ?

A set of operations, performed in accordance with a definite procedure, that compares the measurements performed by an instrument to those made by a more accurate instrument or a standard for the purpose of detecting and reporting, or by adjustment, errors met in the instrument tested. 

»Purpose of Calibration

To ensure readings from an instrument are consistent with other instruments and to determine the accuracy of the instrument i.e. that it can be trusted for its observed/displayed measured value.

»The value of calibration for industry

To ensure that products are manufactured to specifications.

To demonstrate that the industry operates a quality system and technically competent and are able to generate technically valid results.

To increase quality & value of product.

The calibrated measuring instruments (working standards) have the assurance of an unbroken chain of national/international measuring standards

»What is Traceability ? 

Property of the result of a measurement or related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties.

»Uncertainty- How accurate are your measurements ?

It is a measure of the quality of a measurement & provides the means to assess & minimize the risks and possible consequences of poor decision. 

»Calibration Interval-Validity Period.

The equipment is of good quality and is of proven adequate stability.

If any suspicion or indication of overloading or mishandling arises, the equipment will be checked immediately and thereafter at frequent intervals until it can be shown that stability has not been impaired.

The extension of validity period is based on factors such as history of stability, frequency of use, accuracy required, ability of staff to perform regular checks and successful participation in proficiency testing programs. It is the responsibility of the testing authority to provide evidence that its calibration system ensures that confidence in the equipment can be maintained.
