What is Technical Standardization Information (TNI)?

Technical Standardization Information (TNI) are technical standardization documents published by ÚNMZ for informational purposes. They are designated by the abbreviation TNI and a six-digit number following the same classification principles as Czech technical standards (ČSN). They very often incorporate technical reports from CEN, CENELEC, or ISO. TNI documents are valid for three years, with the possibility of extension.
