Esempio di designazione. Caratteristiche costruttive: tolleranze, tiro nominale (vedere CEI 9- 2), armatura, estremità, fondazioni (incastro). Materiale: per l' armatura: tondo di acciaio, avente resistenza a trazione r maggiore o uguale 750 n/mm2; carico di snervamento maggiore o uguale 480 n/mm2; allungamento a rottura a maggiore o uguale 12%; per il conglomerato cementizio: conglomerato cementizio avente carico di rottura a compressione, dopo 28 d di stagionatura, non minore di 5500 n/mm2. Prove e procedimenti: verifica della distribuzione dei tondi dell' armatura; prova di trazione sui tondi dell' armatura; prova di compressione su provini di conglomerato cementizio (vedere dm 16 giu 1976); esame a vista dei pali e verifica delle loro dimensioni; prova di flessione sul palo; verifica della massa individuale dei pali. Origine: UNIFER 9.62.
