The Laboratories of Italcertifer S.p.A. have the necessary equipment and skills to perform environmental and job safety tests (or Job Safety Analysis, JSA) in the railway sector, in accordance with national and international reference standards. Lab technicians and engineers perform the following tests:

• Measures for the evaluation of microclimatic comfort in accordance with the Italian Legislative Decree n. 81 of 9 April 2008, and with the international standards UNI EN ISO7730, EN ISO7726, EN ISO8986, and EN ISO9920 for the determination of PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) benchmarking indices.
• Measures for the evaluation of illuminance and emergency lighting in accordance with the Italian Legislative Decree n. 81 of 9 April 2008  and the international standards EN 12464-1, EN 12464-2 and EN 1838, with the aim of verifying the conditions for the effective and accurate performance of visual tasks, i.e. the compliance with the lighting requirements for the work and transit areas in a railway system and the illumination of the tracks to reach the collection points.
• Measures for the assessment of optical and light pollution, in accordance with national/regional and international decrees DS/CEN/TR 13201-1, DS/CEN/TR 13201-2, DS/EN 13201-3, DS/EN 13201-4, and EN 12464-2, in order to verify the dispersed flux towards unintentionally illuminated objects (optical pollution), and the dispersion of the luminous flux towards areas outside those functionally illuminated to protect the activity of astronomical observatories (light pollution).
• Measures for the assessment of noise impact in accordance with the Italian Presidential Decree (DPR) n. 459 and Italian Ministerial Decree (DM) of 16/3/1998 with the aim of preventing and containing noise pollution of railway infrastructures.
• Measures for assessing workers' exposure to noise in accordance with the Italian Legislative Decree n. 81 of 9 April 2008, as well as the UNI 9432 and UNI EN ISO 9612 Standards, aimed at assessing the noise risk the workers are exposed to.
• Measures for assessing the exposure of workers to electromagnetic fields in accordance with the Italian Legislative Decree n. 81 of 9 April 2008 and the International Standards CEI EN 50500, CEI EN 50444, and CEI EN 50499, with the aim of evaluating the electric field and the index of exposure to magnetic fields produced by intentional and unintentional sources.

Vibration measurements in accordance with the provisions of the Italian Legislative Decree 81/2008, as well as the ISO 2631-1 and ISO 5349 standards.

Italcertifer Laboratories have measuring instruments compliant with the provisions of the international reference standard. The measuring instrumentation is subject to periodic calibration and is kept under control by the Italcertifer Laboratory through an adequate metrological confirmation process.

Italcertifer S.p.A. Laboratories have the necessary instrumentation to perform electromagnetic compatibility tests on vehicles, systems, and sub-systems in the railway sector, in accordance with the European reference standards. This equipment allows to perform the following tests:

• assessment of the level and verification of compliance with the limits of electromagnetic emissions of vehicles and railway systems to the external environment in the range 9 kHz - 1 GHz, defined by CEI EN 50121-3-1
• assessment of the level and verification of compliance with the limits of electromagnetic emissions between railway vehicles and axle counter systems, in the range 10 kHz - 1.3 MHz, defined by the CEI EN 50592 Standard
• assessment of the level and verification of compliance with the limits of the magnetic fields generated by electronic and electrical devices in the railway environment with reference to human exposure, in the range 0 Hz - 20 kHz, in accordance with CEI EN 50500. 

 

The scope of the activities is to verify that the system under test does not generate and propagate electromagnetic energy capable of interfering with and compromising the correct functioning of other systems located nearby or that could be harmful to the health of the operator during his normal work.

Italcertifer Laboratories have special tools dedicated to each test:

CEI EN 50121-3-1

• Frame antenna for measuring the magnetic field in the 9 kHz - 30 MHz frequency bands;
• TriLog antenna for measuring the electric field in the frequency bands 30 MHz - 1 GHz;
• Frequency analysis of the signals carried out using an EMI receiver;

CEI EN 50592

• Low frequency antenna for measuring magnetic fields in the 10 ÷ 100 kHz band;
• High frequency antenna for measuring magnetic fields in the 100 kHz ÷ 1.3 MHz band;
• Acquisition system with diversified sampling frequency based on the type of antenna used;

CEI EN 50500

• Portable Hall effect probe used for the measurement of static magnetic induction;
• Triaxial antenna for measuring low frequency magnetic induction;
• Dedicated acquisition systems based on the measurement instrument used.

All the measuring equipment used comply with the provisions of the international reference standard, subject to periodic calibration and are kept under control by the Italcertifer Laboratories through an adequate metrological confirmation process.

Italcertifer S.p.A. Laboratories have the appropriate instruments and skills to perform temperature measurements for determining the thermal performance of electrical and electronic components and the thermal characterization of various elements of railway vehicles.

Combining them, if necessary, with surface pressure measurements to complete the thermal study case with the aerodynamic one.

At the customer's request, components in the long-term stress test phase can be measured and monitored, accurately determining the operating temperature of the sample object of the test moment by moment, in order to guarantee safety in the test and analysis of thermal performance of the tested component.

The temperatures of electrical components can be measured such as:

• Electrical and distribution panels;
• Electronic devices;
• Batteries;
• Power cables;
• Mechanical components.

Specifically, on railway vehicles:

• Electric and endothermic motors;
• Reducers;
• Traction circuits;
• Rheostats;
• Wheelsets;
• Temperatures of the braking systems;
• Brake discs;
• Wheels;

It is possible to carry out thermal characterization through various methods and measuring instruments such as: pyrometers, thermocouples and PT100 platinum resistance thermometers, thermal imaging cameras with the use of multi-channel telemetry for the transmission of signals, when necessary.

Our temperature detection systems allow you to operate in multiple contexts, our vast set of measuring instruments allows you to:

• perform remote sensing measurements ensuring a non-destructive and non-intrusive control of the analysed bodies;
  
• maintain safety distances in critical applications;
• monitor processes at critical temperatures;
