| Definition (BS) | Prečnik (d) cilindra od istog čelika (dužine ≥3d) u kojem bi BRZINA HLAÐENJA u njegovom centru trebalo da bude identična NAJMANJOJ BRZINI HLAÐENJA, zabilježenoj kod određenog proizvoda od gvožđa i čelika, za iste uslove HLAÐENJA.
Ekvivalentni prečnik nije isti kao onaj određen pri termičkoj obradi, (vidi EN 10083 – 1 i EN 10083 – 2).
