It is shown that the current version of standards ISO 5725-1…6 includes insufficiently the main ideas of statistical thinking into its content. Moreover the necessary prerequisite of any measurement – stability of measurement process – looks like some kind of foreign body within the main frame of these standards. All these points are especially notable in the examples presented in the ISO 5725-6. Analysis shows that this part of 5725 standards does not respond to the basic requirement of any standard: to be an operational procedure for the best way of getting necessary results.

The measurement tasks for industrial and nonindustrial applications over long periods are constant. The measurement solutions are changing with the applicable technologies. Currently the influence of innovative smart computers and cloud computing receives enormous proportions. Smart computers and cloud computing are also the enablers for innovative measurement education and training.
Aim of the paper is to describe selected success stories of the so far unlimited innovative capabilities of smartphones with cloud computing for selected tasks in measurement engineering, education and training.

The present study it consists of a methodology developed in the Instituto Nacional de Metrologia, Normalização e Qualidade Industrial - INMETRO - (Pressure Laboratory -LAPRE) for the calibration of the vacuum sensors such as: capacitive diaphragm manometers, pirani, spinning rotor gauge and others. The used methodology is based on a program of calibration developed in the INMETRO/LAPRE having as principle the comparative method the transference standards. The method uses the analysis statistics as support. The calibration of these measurers in the LAPRE initiates the national metrologic chain for low pressures. Due to the great amount of instruments to be calibrated in the country it is necessary to spread, to stimulate and to guide the techniques of calibration of these sensors. With the transference of the jobs of calibration of these sensors after the certification of these according to the requisite for laboratories of norm ISO-17025 consequently the traceability and metrologic reliability of the measurements will be evidenced. Additionally the method makes possible also a study at any time of the repetitiveness of the calibrated instrument.

Primary metrological laboratories have been and are involved in the characterisation of vacuum gauges to be used as transfer gauges at various levels (comparisons or dissemination). In the present paper, some of the main characteristics of the most popular gauges in the whole pressure range from the atmosphere down to ultra-high vacuum are presented and discussed together with a short presentation of the primary standard systems available at IMGC- CNR.

The scope of this study is a review of the studies on the pressure transducers designed at the TÜBİTAK-UME by utilizing Finite Element Method (FEM) for stress and strain analysis to optimize the design parameters prior to the construction of the pressure transducer prototypes. The constructed and investigated pressure transducer, has a free hardened AISI 4340 steel active element. Hydraulic gauge pressure is applied to the inside and both open ends of this active element. The FEM analysis was conducted by investigating one half of the element in three dimensions and realized at three different pressure values of 60, 100 and 150 MPa. This study presents the FEM output stress and strain values. The validity of those values was established by comparing them with the results obtained from the strain gauge measurements. The relative difference between the two value sets was determined as being lower than 13% of the full scale. The presented results will be helpful for the appropriate design of this kind of pressure transducers using FEM.
