ABSTRACT

In general, the primary objective of control is to guarantee that products are able to meet the requirements for which they have been created. This is the basic principle of quality control (QC). Nowadays, the philosophy of quality is widely spread in all industrial fields and, in a very competitive market, it is considered a necessary tool to demonstrate the quality of the company and of its products. As a consequence, much experience has been gained in developing fast and effective testing procedures to be introduced in the industrial production chain. QC and quality assurance (QA) processes are usually codified by manuals prescribing a series of ‘pass or fail’ tests to be carried on at fixed steps of the production process. Their goal is to assess the quality of the basic components and the effectiveness of the working phases.
