geijkt

Geijkt is a Dutch term meaning calibrated or verified for accuracy, primarily used for measuring instruments. The word is the past participle form of the verb ijken, which means to calibrate or verify. When an instrument is geijkt, its accuracy has been checked against recognized standards and a certificate or stamp indicating geijkt status is issued. This status signals that the instrument may be used for official measurement, trade, or consumer protection purposes, and that it requires periodic re-testing to maintain validity.

In practice, geijkt applies to devices such as scales used in shops, fuel and gas dispensers, water and electricity meters, thermometers, and other measurement instruments used in commerce. The calibration process typically involves comparing the instrument's readings to known reference standards, adjusting if necessary, and documenting the results. A validity period is assigned, after which the instrument must be re-ijken and re-certified.

Many countries regulate geijkt devices under metrology and consumer protection laws. The certificate or stamp helps authorities verify that measurements presented to consumers or during transactions are within permitted tolerances. The term is sometimes translated as calibrated or certified in English-language contexts, but geijkt carries a formal connotation tied to regulatory compliance.
