Description
Gastronorm (GN), sometimes spelled Gastro-Norm, is a European standard for kitchenware tray and container sizes that is commonly seen worldwide in the catering and professional food industry, as well as in certain parts of the high-end consumer market. Gastronorm is generally used worldwide except in the United States, which has its own domestic system. The gastronorm standard was first introduced in Switzerland in 1964 and became an official European standard in 1993 with the EN 631 standard.
