Dear Reader, 

the other 6 papers published in this last issue of 2015 are 
related both to IMEKO TC1 and TC12 and to another 
scientific event that took place in Italy (the 2015 Italian 
Conference on electrical and electronic measurements 
organized by GMEE and GMMT). The last paper in this issue 
is a freely submitted paper.  

The paper by Crenna et al. covers the topic of measuring 
human movements in the expanding area of measurements for 
biomechanics. The authors present a disciplined approach to 
the assessment of a metrological procedure applied to 
measurement of forces and kinematic quantities associated to 
human movements. The aim is that of allowing reproducibility 
of results by controlling and estimating all major sources of 
uncertainty. 

The next paper by Rainer Feistel is a technical note about 
the thermodynamic role of water in the determination of 
climate changes. The role of salinity and relative humidity is of 
great importance in this case and the metrological requirements 
for the determination of such quantities must be determined 
more precisely if data are to be compared over decade long 
periods of time. This note describes the activities done at the 
international level to promote traceability of measurement 
results in this research area. 

The next paper by Rolle et al. is a technical note covering 
again the topic of measurements for environmental purposes 
and, in particular, the problem of metrological traceability for 
the analysis of atmospheric pollutants. It describes the 
procedures and activities done in this scientific area by the 
Italian   Metrological   Institute,   INRiM.  They  deal  with  the  

 
 

 
preparation of gaseous reference material and with traceability 
issues for measuring the particulate matter. 

The paper by Lancini et al. is related to reliability of railway 
components and to the measurements needed for this scope. 
By using vibration measurements authors show how to detect 
high wear rates in rolling contacts. The procedure and the 
experimental results are presented in depth with a large level of 
detail. It is shown that it is possible to assess wear phenomena 
of wheel and rail steels by using vibrational analysis. 

D’Emilia et al. consider the uncertainty in the calibration of 
three-axis low frequency accelerometers. They analyze both 
static and dynamic calibration up to 4 Hz and present both an 
analysis of the used mathematical model and experimental 
results. They identify the main sources of uncertainty and 
provide suggestions for an effective calibration of these sensors. 

J. Bongiorno and A. Mariscotti authored the last paper in 
this issue. It describes the techniques used to measure the real-
to-earth conductance and the insulating efficiency in railways. 
In the paper it is reported the application of IEC 62128-2 for 
performing such measurements and experimental results are 
also described. Several practical considerations are made, 
including description of the effects of measurement uncertainty. 

This issue contains a very interesting set of papers offering 
an ever increasingly wider view on the possible applications of 
metrology and instrumentation. We are looking forward to the 
issues in 2016, including the extended versions of papers 
presented at the last IMEKO World Congress held in Prague 
this year.  

Have a fruitful reading of this last issue of ACTA IMEKO 
in 2015!
