Mass and Force Metrology

The lab maintains the national primary standard of mass for the Arab Republic of Egypt. The kilogram copy No.58, manufactured from Platinum-Iridium Alloy. This kilogram used for transfer the tractability to the other masses inside and outside the republic. Lab adopts the policy of establishing the traceability of its standards tracing to its own primary standards and avoid the external calibrations.

International Recognition

The primary standards of Mass, Density and Pressure Lab. are recognized from BIPM Based on the agreement of CIPM-MRA and the CMC’s had been published via BIPM KCDB.

International Comparisons

Since 1999 mass, density and pressures lab participating effectively in the comparisons organized within the activities of BIPM and regional metrology organizations like AFRIMETS, EURAMET, APMP and GULFMET. Lab participated in more than 30 key and supplementary comparisons in the laboratory activities.
