Analysis of Standards and Specific Documentation about Equipment of Dimensional Metrology

Currently the certification of quality systems and accreditation of laboratories for metrology and testing are activities of great interest within the framework of advanced production systems. In this context, the availability of standardized documents, complete and efficient as well as specific documents edited by agencies with experience in this field, is especially important to obtain better results and lower costs. This work tries to establish the foundations to evaluate a documental system about equipment of Dimensional Metrology. An integrated and complete system does not exist in international field, so the Spanish case will be analyzed as example to the general study. In this paper we consider three types of instruments commonly used in the field of Dimensional Metrology (vernier calliper, micrometer calliper and mechanical dial gauge) and are passed to analyze the contents of UNE standards that affect them directly, and the two collections of documents produced and edited by the Centro Español de Metrología (CEM), such as "calibration procedures" and "use manuals." Given the results of this analysis, a discussion on the metrological characteristics of the contents of the document in question is developed and recommendations for their use and improvement are proposed.
