Metrology Laboratories

Metrology Laboratory of Hymettus by applying the 17025 standard*

The Metrology Laboratory is part of the industrial facilities of Ymittos of the company Hellenic Defense Systems.

The Laboratory operates on the basis of clearly documented procedures and implements a management system according to ELOT EN ISO / IEC 17025. The laboratory staff is trained on the procedures, methods and proper use of the equipment. They have the experience and ability to perform even the most complex high-precision measurements and tests.

The laboratory covers an area of ​​300 m2 and has been specially designed to ensure the reliability and accuracy of the measurements and tests performed. The Calibration Rooms of the Metrology Laboratory have been constructed on special foundations to ensure the isolation of vibrations. The Laboratory is equipped with special black granite workbenches (classes 1 and 00 according to DIN 876).

The environmental conditions inside the laboratory comply with the international technical specifications for such installations and are maintained by the use of a special air conditioning system that maintains the temperature at 20 ° C ± 0,5 ° C and the humidity at a level between 50% – 60%.

The laboratory equipment includes common and special micrometers, calipers, electronic vertical height meters, granite application plates, standard tile boxes (standard rectangular measuring blocks), category -K -, – 0-, -1-, -2-

Standard spheres and cylinders, calibrators for measuring instruments and the following measuring machines:

PMM 866-3D measuring machine, for large pieces – accuracy: up to 0.50 μm.

SIP measuring machine – 302M, for cylindrical and flat objects, internal and external threads, etc. – accuracy: up to 0.40 μm.

UMW – SKI measuring microscope, with magnifying glasses and accessories, with incident light for “blind” measuring points, radii, contour measurement, angles, radii, thread angles, etc.

Mechanical comparator TESA UPD, complete with accessories (electronic precision thermometer with 4 sensors, monochrome light source, optical level, etc.) for the calibration of measuring plates (blocks) – precision class: 0,1 & 2.

MINI – HORIZONTAL calibration device, for the calibration of measuring clocks (lever type, etc.) and the calibration of various small instruments – accuracy: up to 0.40 μm.

Vertical height measuring device TRIMOS V600 +, for height measurement, as well as distances between centers of holes – accuracy: 1 μm.

MECMESIN TWC-1 & TWC-4 torque calibration devices.

Standard weights for calibration of F&N class balances.

The design and equipment of the laboratory, as well as its specialized staff ensure the reliability of the wide range of applications performed in the laboratory for the company Hellenic Defense Systems and its customers.
