Updated Competence Database
The Competence database is based on the member's competence profiles in geometric and dimensional metrology. Each profile consists of several services which have been defined according to different dimensional metrology items (instruments, standards and artefacts, tools and methods, specific objects as well as supporting tasks).
The current database figures are:
- 45 active members
- 473 member records
- 2755 services defined
- 3012 available parameters
- 1266 specified parameters
- thread measurement in progress
Online Calculation
EVIGeM offers the possibility of calculating the pitch, diameter or indicated value for thread measurements according to the guideline EA-10/10 online on this website.

TetraCheck
TetraCheck is a revolutionary verification system of measurement machines and machine tools, with which companies will be able to analyse in an easy and ultrafast way their machines´ accuracy. This system, developed by expert metrologers, needs less than 10 minutes for the verification of a machine. It is an optimum method to carry out the "interim checking", which is indispensable...

Various glossary term:
Skewness of the assessed profile
Psk, Rsk, Wsk Quotient of the mean cube value of the ordinate values Z(x) and the cube of Pq, Rq or Wq respectively, within a sampling length NOTES 1 The above equation defines Rsk; Psk and Wsk are defined in a similar manner. 2 Rsk, Psk and Wsk are measures of the asymmetry of the propability density function of the ordinate values. 3 These parameters are strongly influenced by isolated peaks or isolated valleys.
