Measuring is an important part of the process of manufacturing and developing products. Measurement for the production and development of standards is required for a healthy relationship between the buyer and the seller, as well as to ensure the conformity of the product manufactured with the relevant standards. Measurement is also required for monitoring and monitoring the process, either for optimization or for process modeling. In order for a measurement to be valid and accepted by all parties and interpreted in a manner, a common measurement standard should be detectable through a series of chain-linked and continuous comparison. Calibration laboratories are in the judgment of the circles of this chain, which ultimately relate a measurement to its definition. These definitions are provided by the international system and agreed upon internationally. Due to the evolution of ISO standards and the importance and position of calibration, the role of calibration laboratories is increasing in this standard.
