referentiemasses
Referentiemassen, in metrology, are reference masses used to calibrate and verify mass-measuring instruments such as analytical balances, precision scales, and industrial weighers. They provide a stable, known mass that allows instruments to produce accurate readings and to demonstrate traceability to the International System of Units (SI).
Construction and characteristics
Referentiemassen are typically made from corrosion-resistant metals such as stainless steel or high-density alloys. They are
Certification and traceability
Each referentiemassa has markings that indicate its nominal value, tolerance, material, and a certificate of calibration.
During calibration, a balance or scale is adjusted so that its readings match the known masses of
Since the redefinition of the kilogram in 2019, the SI unit is fixed to a fundamental constant,
