METRICA, l’archivio istituzionale della produzione scientifica dell’Istituto Nazionale di Ricerca Metrologica, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ente. METRICA utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
Analisi dei dati forniti dai Laboratori Accredia durante il confronto inter laboratorio per la grandezza momento torcente.
In questo rapporto tecnico si descrivono le operazioni di Conferma Metrologica del Sistema di misura dei Parametri S in connessione 3.5mm, nel campo di frequenza da 50 MHz a 26,5 GHz, per la validazione dei nuovi cavi Rosenberger 2.4mm – 2.92mm. Il risultato di queste operazioni è la determinazione dell’Indice di Compatibilità che, se <1 in valore assoluto, valida il sistema di misura INRIM.
ISO 14253-5:2015 specifies concepts and terms for evaluating the uncertainties of the test values derived according to a test protocol agreed upon by the parties and relative to instrument indication(s), obtained in verification testing of GPS indicating measuring instruments. NOTE The uncertainty of the test values, referred to as test value uncertainty, is not to be confused with the measurement uncertainty associated with using that indicating measuring instrument to measure workpieces. T...
This part of ISO 10360 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences link 5 of the chains of standards on size, distance, radius, angle, form, orientation, location, run-out and datums. For more detailed information of the relation of this part of ISO 10360 to other standards and the GPS matrix model see annex B. Coordinate measurement technology is widely used in industrial metrology to assess feature...
This document defines the concepts of a reference temperature and the standard reference temperature and specifies the standard reference temperature value for the specification of geometrical and dimensional properties of an object. Some examples of geometrical and dimensional properties include size, location, orientation (including angle), form and surface texture of a workpiece. This document is also applicable to the definition of the measurand used in verification or calibration.
