Long term stability of silicon roughness standards

In 1986 first roughness reference standards made of silicon were produced at the Laboratory for precise measurements of length (LFSB), which is now a part of Croatian Metrology Institute (HMI) designated as HMI/FSB-LPMD. Until then, roughness standards were made either from steel or glass. Due to world-class quality of these standards and their outstanding metrological characteristics, they were used in several European countries ; among others, standards are currently being used as roughness reference standards in Italy, Slovenia and Croatia. After 27 years of use, we decided to conduct a research of metrological features on two silicon roughness standards, used as primary standards for roughness in Croatia.
