This requirement does not apply to surface imperfection with a depth equal or less 0,3 mm. 8.4.1.5 Surface imperfections which encroach on the specified minimum wall thickness shall be considered defects and tubes containing these shall be deemed not to conform to this Part of EN 10216. 8.4.2 Internal soundness 8.4.2.1 Leak Tightness The tubes shall pass
a hydrostatic test (see 11.8.1) or electromagnetic test (see 11.8.2) for leak-tightness. Unless option 7 is specified, the choice of the test method is at the discretion of the manufacturer. Option 7: The test method for verification of leak-tightness in accordance with 11.8.1 or 11.8.2 is specified by the purchaser. 8.4.2.2 Non-Destructive Testing The tubes of test category 2 shall be subjected to a non-destructive testing for the detection of longitudinal imperfections, in accordance with 11.11.1. Option 8: The tubes of test category 2 shall subjected to a non-destructive testing for the detection of transverse imperfections in accordance with 11.11.2. Option 9: The tubes of test category 2 shall be subjected to a non-destructive testing for the detection of the laminar imperfections in accordance with 11.11.3. 8.5 Straightness The deviation from straightness of any tube length L shall not exceed 0,001 5 L.
Deviations from straightness over any one metre length shall not exceed 3 mm. 8.6 Preparation of ends Tubes shall be delivered with square cut ends. The ends shall be free from excessive burrs. Option10: The tubes shall be delivered with bevelled ends (see figure 1). The bevel shall have an angle α of 30° °+°50with a root face C of 1,6 mm ± 0,8 mm, except that for wall thickness T greater than 20 mm, an agreed alternative bevel may be specified SIST EN 10216-2:2003+A2:2007

Preferred outside diameters D and wall thicknesses T have been selected from #EN 10220$ and are given in Table 6. NOTE Dimensions which are different from those in Table 6 may be agreed. Option 11: The tubes shall be delivered in accordance with one of the following sets of dimensions as specified at the time of enquiry and order:  outside diameter D and minimum wall thickness Tmin;  inside diameter d and wall thickness T for d ≥ 220 mm;  inside diameter d and minimum wall thickness Tmin for d ≥ 220 mm;  minimum inside diameter dmin and wall thickness T for dmin ≥ 220 mm;  minimum inside diameter dmin and minimum wall thickness Tmin for dmin ≥ 220 mm.
