Metrology Laboratory
EMSYST-6 maintains two metrology laboratories, for legal and industrial metrology tests of electricity and water measurements:
Verification laboratory, licensed by State Agency of Metrological and Technical Surveillance according to Art. 50 par. 1 and 2 of the Act on Measurements. The scope of the License encompasses one- and three phase electricity meters classes 0.2s, 0.5s, 1, 2 and 3, and water meters for cold and warm water classes A, B and C for flow values. The laboratory meets the ISO IEC 17025 requirements which, in Bulgarian legislation, are prerequisites for obtaining the license.
Calibration laboratory, accredited in accordance with ISO / IEC 17025, for calibration of all types single- and three phase active and reactive energy standards and electricity meter test benches, and of portable flow meters and flow test stations operating with water.
Verification laboratory customers are all end users of electricity and water services, and all electricity service organizations, due to submit periodically their meters for metrological verification according to the Act on Measurements. The verification intervals differ depending on the type of meter and its field of use.
The calibration laboratory’s customers are metrological, industrial and scientific laboratories, licensed to perform metrological verification of electricity or water meters, declaring readiness to meet the ISO 9001 quality system requirements, or simply being involved in trading with electrical energy or water and being aware that their billing instruments have to be periodically calibrated to higher accuracy class standards. Here, EMSYST-6 Ltd applies its expertise in manufacturing high accuracy class standards in the field of their use. Almost all standards, manufactured by EMSYST-6 and sold, have to be calibrated, according to their accuracy class, to the corresponding higher class standard in the calibration laboratory.
