It is recommended that the level 3 personnel be certified in accordance with EN or, at least, an equivalent to it.
The operating authorisation issued by the 1020-1 shall be in accordance with a written procedure. The definition of levels 1, 2 and 3 can be found in the appropriate standards, e. EN and EN 6.
Normalized includes normalized rolled. The 10201-1 shall be left to the discretion of the manufacturer, but shall be stated to the purchaser at the time of enquiry and order. Hollow sections treated in such a way shall be designated: Bw Cold formed hollow sections with subsequent heat treatment to obtain properties equivalent to those obtained by normalizing rolling are deemed to meet the requirements of this standard. The maximum carbon equivalent value CEV for all grades, based on the cast analyses, given in Table A.
When determining the CEV the following formula shall be used: 102101 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 Table A.

In these cases, verification of the grain size is not required. General requirements for welding of the products in accordance with this European Standard are given in EN and Sn 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: NOTE 2 By using guidelines, specified for example in ENEN 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.
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. For fine grain structural steel hollow sections manufactured by either a seamless or welded process, repair of the body by welding shall not be permitted unless otherwise agreed.
NOTE Dimensions, sectional properties and mass per unit length for a limited range of sizes of hot finished structural hollow sections are given in EN The purchaser should preferably select hollow section dimensions from this limited range of sizes.
The test report shall contain the following codes and relevant information in accordance with EN A — Commercial transactions and parties involved.
B — Description of products to which the test report applies. C — Information on tests as follows: Where this document is specified, the purchaser shall notify the manufacturer of the address of the organization or person nominated by him to carry out the inspection and validate the inspection document. It shall also be agreed which party shall issue the certificate. The inspection certificate shall contain the following codes and related information in accordance with EN B — Description of products to which the inspection certificate applies.
CC03 —Direction of test pieces and test temperature; CC13 — Tensile test — Test piece shape and test results; CC43 — Impact test — Test piece type and test results, if applicable; CC92 —Cast analysis and, if applicable, product analysis. Longitudinal or transverse samples at enn discretion of the manufacturer.
A test unit is defined as a quantity of hollow sections from one or more cast s of the same grade and dimensions, manufactured by the same process i. The following samples shall be taken from one sample product of each test unit: Table 4 — Test units Licensed Copy: In addition, the following requirements shall apply: NOTE Test piece size is dependent on the actual thickness of the sample and, for circular or elliptical hollow sections; allowance also needs 10210- be made for the curvature of the section.
The choice of a suitable physical or chemical analytical method for the analysis shall be at the discretion of the manufacturer. In case of dispute, the method used shall be agreed taking into account CR Impact tests shall be carried out at the temperatures specified in Table A. For the specified yield strengths in Tables A. For thicknesses less than 3 mm, the percentage elongation may be reported for a gauge length of 80 mm or 50 mm see 8.
