6.6.2 For non-alloy steel products supplied with specific inspection and testing the following option may be specified (see 7.1): Option 1.2 the recording on the inspection certificate of the Cr, Cu, Mo, Ni, Ti and V content (cast analysis). 6.7 Mechanical properties 6.7.1 Under the inspection and testing conditions as specified in Clause 7 and in the delivery condition specified in 6.5, the mechanical properties shall conform to the relevant requirements of Tables A.3, B.4 or B.5. NOTE Stress relief annealing at more than 580 °C or for over one hour may lead to deterioration of the mechanical properties.
6.7.2 For impact tests, standard V-notch test pieces in accordance with EN 10045-1 shall be used. If the nominal product thickness is not sufficient for the preparation of standard test pieces, the test shall be carried out using test pieces of width less than 10 mm, but not less than 5 mm. The minimum average values given in Tables A.3, B.4 and B.5 shall be reduced in direct proportion of the actual width of the test piece compared to that of the standard test piece. Impact tests are not required for specified thicknesses < 6 mm. SIST EN 10219-1:2006

b) the impact properties of structural hollow sections of steel qualities JR and J0 are not verified unless otherwise specified by the purchaser at the time of enquiry and order. Option 1.3 for products in qualities JR and J0 supplied with specific inspection and testing (see Option 1.6), the verification of the impact properties is specified. 6.8 Technological properties 6.8.1 Weldability The steels specified in this European Standard are weldable.
General requirements for welding the products in accordance with this European Standard are given in EN 1011-1 and EN 1011-2. NOTE 1 When welding these products, as product thickness, strength level and CEV increase, the occurrence of cold cracking in the welded zone forms the main risk. Cold cracking is caused by a combination of the following factors:  high levels of diffusible hydrogen in the weld metal;  a brittle structure in the heat affected zone;  significant tensile stress concentrations in the welded joint. NOTE 2 By using guidelines, specified for example in EN 1011-1, EN 1011-2 or any other relevant standard, the recommended welding conditions and the various welding ranges for the steel grades can be determined. These will vary depending on the product thickness, the applied welding energy, the design requirements, the electrode efficiency, the welding process and the weld metal properties. 6.8.2 Suitability for hot dip galvanizing Option 1.4 the products shall be suitable for hot dip galvanizing. 6.9 Surface condition 6.9.1 The hollow sections shall have a smooth surface corresponding to the manufacturing method used; bumps, cavities or shallow longitudinal grooves resulting from the manufacturing process are permissible, provided the remaining thickness is within tolerance. Surface defects may be removed by the manufacturer by grinding, provided that the thickness of the hollow section after the repair is not less than the minimum permissible thickness in accordance with EN 10219-2. 6.9.2 The ends of the hollow section shall be cut nominally square to the axis of the product. 6.9.3 For both non-alloy and fine grain hollow sections, repair of the weld shall be permitted. 6.9.4 For non-alloy hollow sections, repair of the body by welding shall be permitted unless otherwise specified. The conditions under which, and the extent to which, welding repair to the body may be carried out shall be agreed between the manufacturer and the purchaser. Option 1.5 repair of the body by welding shall not be carried out. SIST EN 10219-1:2006
