TNI is a national document or taken-over technical report (TR) or publically available specification (PAS) of European or international standardization organizations. - A technical informative document which contains technical data or technical solutions not included in valid standards. TNI usually contains certified data from withdrawn standards, whose preservation is useful, or technical requirements that have not got the assumption of “designation” yet to be sold or produced as a standard. They are marked with the abbreviation TNI and a six-digit number which is in accordance with Slovak technical standards sorting (STN). - In the case of taken-over international or European document – the product is taken over from European and international standardization organizations TR and PAS supplementing set of standards and specifications with TNI designation. The labeling of these documents is similar to taken-over standards (TNI/TR and TNI/PAS).
