Values at the first thickness band or product form of each material (EN 1999-1-1 · t ≤ 200 mm · EP, ET, ER/B; EN 1999-1-1 · t ≤ 20 mm · EP, ET, ER/B). A minimum and a characteristic value are not the same kind of number — read the ratio as a guide. Each material's page lists every band and every source.
