| a The impact properties are verified only when Option 1.3 is specified. For thicknesses>3mm and section sizes D/T<15(round)and(B+H)/2T<12,5 (square and rectangular)the minimum elongation is reduced by 2.For thicknesses≤3mm the minimum value for elongation is 17%. e For section sizes D/T<15(circular)and(B+H)/2T<12,5(square and rectangular)the minimum elongation is reduced by 2. d For thicknesses<3mm see 9.2.2. e For impact properties for reduced section test pieces see 6.7.2. f This value corresponds to 27J at-30℃(see EN 1993-1-1). | |||||||||
