Hinweis der Redaktion

  1. Πριν από λίγους μήνες το ΕΙΜ προχώρησε σε μία γενικευμένη αναβάθμιση του Εθνικού Προτύπου Χρόνου και Συχνότητας. Στην παρούσα εργασία θα αναλύσουμε τον σχεδιασμό και τις λύσεις που υιοθετήθηκαν κάνοντας κάποιες αναφορές στην καταγραφή του χρόνου σε παγκόσμιο επίπεδο.
  2. Although the word “metrology” derives from the Greek language, and metrology was already developed in ancient Greece, modern metrology established in Greece only in early 30’s with Legal Metrology . Scientific metrology, which is usually represented by a National Institute of Metrology, established only in 1994, through the foundation of the Hellenic Institute of Metrology. Τ he Hellenic Metrology Institute ( ΕΙΜ ) , is the only NMI in Greece, founded by the law 2231/1994, which was approved by the National Parliament. EIM is supervised by the Ministry of Development and is a legal body ascribing to private legislation. The first building site of EIM was completed in 1996 . Actually, it was a construction of an old industrial building and was too small and most of the labs were hosted in private calibration laboratories that fulfilled the appropriate environmental conditions. T he staff recruitment started in late 1997. The infrastructure of EIM (buildings, equipment) was funded by the 2nd European Framework Program of the E.U. during the period 1994-1999. The equipment set in operation gradually since 1998 and the QS implementation started in 1999. The following year, 2000, EIM begun to offer its services to customers. In early 2001 the second, and main, building site completed but it became operational only in the end of 2002, as there were many problems, concerning especially the stabilization of the environmental conditions. Upon the completion of the second building, the installation of most of the primary stds became feasible.
  3. The management structure of EIM is represented by its organogram as follows. Details of the responsibilities and the authorities of the staff are determined according to the decisions of the Management Council of EIM and described in the job descriptions and the procedures of the quality system. The laboratories are grouped in three sections as follows: Section of Mechanical Measurements including the laboratories of Mass, Force-Torque, Pressure, Flow of Liquids & Gases – Viscosity, Volume, Density. Section of Physical Measurements including the laboratories of Temperature & Humidity, Dimensional Measurements, Acoustics & Vibrations and Optics & Photometry. Section of Electrical Measurements, including the laboratories of Electrical Measurements at High Frequencies, Electrical Measurements at Low Frequencies and Time – Frequency.
