Standardmassa
Standardmassa, or standard mass, is an artifact of known mass used as a reference in mass metrology to calibrate weighing instruments such as balances and scales. These masses provide a stable, traceable benchmark that enables laboratories to determine and maintain the accuracy of their measurement systems. The mass value of a standard mass is linked through a formal calibration chain to the SI kilogram, ensuring consistency across instruments, laboratories, and industries.
Historically, the kilogram was defined by the International Prototype of the Kilogram (IPK) and copies that
Construction and handling methods focus on stability, durability, and minimal interaction with environment. Standard masses are
In modern metrology, standard masses continue to fulfill the role of transfer artifacts that enable accurate,
