A growing number of measurements in commercial and industrial sector needs to refer to the traceability to the national (and also international) standards. Since the internet-enabled metrology is rapidly developing in the recent years, it offers new possibilities for calibration services. This paper focuses on the problem of the visualization of the internet-enabled calibration process and instruments. The main goal is to identify the solution for real-time data monitoring and control of measurement equipment.

Enforcement of Directive 40/2004/EC binds the EU member countries to define their legislative proceedings on the minimum health and safety requirements regarding the exposure of workers to the risk arising from physical agents (electromagnetic fields).
In this paper guidelines for the determination and evaluation of low-frequency electromagnetic fields of high-voltage power stations are proposed. They are based on experiences gained with numerical calculations and measurements and are compatible with measurement practices and demands of international labot conventions and EU Directives.

A research project on the measurement of emission factors in critical driving conditions arising from a cooperation among University of Sannio, Istituto Motori of CNR, and some companies of Italian Regione Campania is started. In particular, in this paper, a procedure of automatic feature extraction and data classification of vehicle driving sequences by means of Wavelet analysis and Cultural Algorithms is proposed. The procedure improves the lack of sensitivity of the state-of-the-art statistical methods to variations of vehicles instantaneous kinematic parameters (e.g. speed, acceleration) through a simple heuristic link between vehicle speed and road traffic data.

This paper presents both hardware and software of system for measurement of welding process electric parameters.
The distinctive feature of the system is its application for control of the process of high-quality contact micro-welding of critical destination products which is characterized by the pulse current in the range from 100 A to 20kA and by the pulse duration from a few to hundreds of milliseconds. The system is portable and consists of the measuring coaxial shunt, oscillograph and computer with a software. Structure and main principles of constructing the system components are described. Its technical and metrological parameters are given.

The reactive energy meters used in electric distribution networks are based on a conventional definition of reactive energy (or power) for sinusoidal voltages and currents, containing only the fundamental frequency component. As a consequence, the performances of reactive energy meters in the presence of harmonic distortion are not tested and their accuracy specifications can be very different from the nominal ones, that are evaluated in sinusoidal conditions. In this paper the authors present a comparative study of the performances of different reactive energy meters, both electromechanical and static, in the presence of harmonic distortion; the study is supported by several simulations and experimental tests.
