Option 7: Reduced internal roughness of
¶ 2 8.4.3);
Option 8: Measurement of surface roughness (see 8.4.4);
Option 12: Non-destructive testing for the detection of longitudinal imperfections (see 8.4.7);
Option 21: another specified length and/or tolerance (see 8.5.2);
Option 22: Reduced maximum deviation from straightness (see 8.5.3); SIST EN 10305-6:2016

Option 24: higher test pressure for hydrostatic test (see 11.6.2);
Option 28: alternative marking (see Clause 12);
Option 31: protection by phosphatization (see 13.1);
Option 32: protection by electrolytical zinc coating (see 13.1);
Option 37: protection of tube ends (see 13.1);
Option 38: unbundled tubes or specific method of packaging (see 13.2). 6.3 Example of an order 1 000 tubes with an outside diameter of D = 20 mm and a specified wall thickness of T = 2,5 mm in accordance with this document, made of steel grade E235, delivered in standard lengths with an inspection certificate 3.1 in accordance with EN 10204:2004: 1 000 tubes – D 20 x T 2,5 – EN 10305-6 – E235 – standard length – inspection certificate 3.1 7 Manufacturing process 7.1 Steelmaking process The steel making process is at the discretion of the manufacturer with the exception that the open hearth (Siemens-Martin) process shall not be employed unless in combination with a secondary steelmaking or ladle refining process. Steels shall be fully killed. NOTE This excludes the use of rimming, balanced or semi-killed steel. 7.2 Tube manufacture and delivery conditions 7.2.1 The tubes shall be manufactured from electric welded tubes by cold drawing. Other suitable methods of cold working are permitted. The tubes shall be delivered in the delivery condition +N, which means that after final cold drawing (or other processing) the tubes are normalized in a controlled atmosphere. 7.2.2 Welding shall be carried out by suitably qualified personnel according to suitable operating procedures. For tube to be used for pressure equipment in categories II, III, and IV (of Directive 2014/68/EU), the operating procedures and the personnel shall be approved by a competent third-party. Tubes not processed according to this requirement shall be marked “C 1”. 7.2.3 All non-destructive testing (NDT) activities shall be carried out by qualified and competent level 1, 2 and/or 3 personnel authorized to operate by the employer. The qualification shall be in accordance with ISO 11484:2009 or, at least, an equivalent to it. It is recommended that the level 3 personnel be certified in accordance with EN ISO 9712 or, at least, an equivalent to it. The operating authorization issued by the employer shall be in accordance with a written procedure. NDT operations shall be authorized by a level 3 NDT individual approved by the employer.
