In three dimensions, the Penrose sculpture exclusively designed by Ars Electronica symbolizes – with its three legs made of three different materials – the most important standards, i.e. national ÖNORM standards, European EN standards and international ISO standards. Representing these bodies of standards, the very first documents in each category can be studied on touchscreens.
ÖNORM M 1501 “Metric threads” (July 1921) is the first ÖNORM standard published by ÖNIG (Austrian Standards Committee for Industry and Commerce).
ÖNORM EN 2 “Classification of fires” (May 1973) is the first EN (European Standard) published by the European Committee for Standardization (CEN).
ÖNORM ISO 1 “Standard reference temperature for geometrical product specification and verification” (January 1975) is the first International Standard published by the International Organization for Standardization (ISO).
