Generalis repraesentatio sine tolerantia indicio
Vexillum numeri et tolerantiae notae gradus in codice iuxta truncum tituli extractionis vel in technicis requisitis et documentis technicis (ut signis inceptis).Exempli gratia, cum medium gradum eligendo, titulus talis est;
GB/T 1804-m
Structurae tolerantiae geometricae non notatae in delineatione secundum gradum in GB/t1184-1996 notentur "tolerantiae geometricae et positionales sine valoribus singularibus tolerantiae".[1]
