<strong>METROLOGY</strong> 2.1.2 Measurement Standards: A measurement standard or etalon, is a material measure, measuring instrument, reference material or measuring system intended to define, realize, conserve or reproduce a unit or one or more values of a quantity to serve as a reference. 10/10
<strong>METROLOGY</strong> Example: The meter is defined as the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second. The meter is realized at the primary level in terms of the wavelength from an iodine-stabilised helium-neon laser. On sub-levels, material measures like gauge blocks are used, and traceability is ensured by using optical interferometry to determine the length of the gauge blocks with reference to the abovementioned laser light wavelength. 11/10
