Samples and test pieces shall be taken at the tube ends and in accordance with the requirements of EN ISO 377. 10.2.2.2 Test pieces for tensile test

The test pieces for tensile test shall be prepared in accordance with EN 10002-1. At the manufacturer's discretion : for tubes with an outside diameter up to 219,1 mm, the test piece shall be either a full tube section or a strip section and shall be taken in a direction longitudinal to the axis of the tube; for tubes with an outside diameter above 219,1 mm, the test piece shall either a machined test piece with circular cross section from an unflattened sample or a strip section and be taken in a direction either longitudinal or transverse to the axis of the tube. 10.2.2.3 Test pieces for impact test

Three standard Charpy V-notch test pieces shall be prepared in accordance with EN 10045-1. If the wall thickness is such that standard test pieces cannot be produced without flattening of the section, then test pieces of width less than 10 mm, but not less than 5 mm shall be prepared; the largest obtainable width shall be used. Where test pieces at least 5 mm width cannot be obtained, the tubes shall not be subjected to impact testing. Unless otherwise specified (see Option 4), the test pieces shall be taken transverse to the tube axis unless Dmin , as calculated by the following equation, is greater than the specified outside diameter, in which case longitudinal test pieces shall be used: Dmin = (T-5) + > 756,25 / (T-5) @ (1)

Page 22 EN 10216-1 : 2002 + A1 : 2004 The test pieces shall be prepared such that the axis of the notch is perpendicular to the surface of the tube, see figure 2

5,65 So using the conversion tables in EN ISO 2566-1.

11.3 Impact test
11.3.1 The test shall be carried out in accordance with EN 10045-1 at 0 qC and, if option 4 is specified, at -10 °C. 11.3.2 The mean value of the three test pieces shall meet the requirements given in table 4. One individual value may be below the specified value, provided that it is not less than 70 % of that value. 11.3.3 If the width (W) of the test piece is less than 10 mm, the measured impact energy (KVp) shall be converted to the calculated impact energy( KVc) using the following equation:

KVc

10 u KVp W

Page 23 EN 10216-1 : 2002 + A1 : 2004 where: KVc is the calculated impact energy, in J; KVp is the measured impact energy, in J; W is the width of the test piece, in mm. The calculated impact energy KVc shall conform to the requirements given in 11.3.2. 11.3.4 If the requirements of 11.3.2 are not met, then an additional set of three test pieces may be taken at the discretion of the manufacturer from the same sample and tested. To consider the test unit as conforming, after testing the second set, the following conditions shall be satisfied simultaneously: the average value of the six tests shall be equal to or greater than the specified minimum value; not more than two of the six individual values may be lower than the specified minimum value; not more than one of the six individual values may be lower than 70 % of the specified minimum average value. 11.3.5 The dimensions in millimetres of the test pieces, the measured impact energy values and the resulting average value shall be reported.

11.4 Leak tightness test
11.4.1 Hydrostatic test The hydrostatic test shall be carried out at a test pressure of 70 bar2) or at a test pressure P calculated using the following equation, whichever is lower:

P

20

S uT D

(3)

where : P D T is the test pressure, in bar; is the specified outside diameter, in mm; is the specified wall thickness, in mm;

S is the stress, in MPa , corresponding to 70 % of the specified minimum yield strength (see table 4) for the steel grade concerned The test pressure shall be held for not less than 5 s for tubes with a outside diameter D less than or equal to 457 mm and for not less than 10 s for tubes with a outside diameter greater than 457 mm. The tube shall withstand the test without showing leakage or visible deformation.
