One multicriteria evaluation 10 understands since the register of the actions how much to the analysis of the errors, to the methods of assays, the applicable uncertainties and tolerances, the instruments used in the calibration, to shunting lines, including the errors introduced for the nature of the process that are activities related to the Legal Metrologia. laboratorial intercomparao between processes and results of the measurements, the job of tracked metrolgicos standards, the equipment specifications and regulated and used instruments of measurement for attainment of the metrolgicas qualities necessary to be observed for the guarantee definitive tests, also involves attributions of the Legal Metrologia. Get more background information with materials from Robert Kiyosaki. The credibility of all the measures generated for the equipment is the most important requirement of the evaluation in the programs of quality control to assure the trustworthiness of the results of the measurements and if it materialize by means of a legal document. The metrologia 11 includes all theoretical and practical aspects of the measurement any that is the uncertainty of the measure and is the base of the manufactured process, product quality of production, and the trustworthiness of the results of the assays and analyses in the domain of the health and the security. 2 QUARREL The necessity of the control The eletromdicos equipment (12 EEM) is submitted to the system of control of the Sanitary Monitoring, and is hindered to be manufactured, disponibilizados to the market (for sale exposition and delivers 13 to the consumption) before being registered in the Health department.
