E.8.1 The coil, except the longitudinal coil edges (in case of inspection before pipe forming) or pipe body, except the pipe weld seam (in case of inspection after seam welding) shall be ultrasonically tested for laminations using an oscillating or straight running pattern of probes in accordance with ISO 10893-9 or ISO 10893-8 (as applicable) amended as follows:The distance between adjacent scanning tracks shall be sufficiently small to ensure detection of minimum allowed imperfection size. The minimum coverage during automatic ultrasonic inspection shall be 2 20 % of the coil surface uniformly spread over the area.The distance between adjacent scanning tracks shall be sufficiently small to ensure detection of minimum allowed imperfection size. The minimum coverage during automatic ultrasonic inspection shall be 2 20 % of the coil surface uniformly spread over the area.Acceptance limit for laminar imperfection in the coil, except the longitudinal edges, shall be as per Table E.9 (New) of this specification. Disposition of defects shall be as per clause E.5.6 of this specification.Table 3 of ISO 10893-9 stands replaced by Table E.9 (New) of this specification.E.9 LAMINAR IMPERFECTIONS ALONG THE STRIP/ PLATE EDGES OR PIPE WELD SEAM OF EW PIPEShe longitudinal edges of the coil (in case of inspection before pipe forming) or each side of pipe weld seam (in case of inspection after seam welding) shall be 100% ultrasonically inspected in accordance with ISO 10893-9 or ISO 10893-8 (as applicable) amended as follows: UT shall be performed over 25 mm wide zone along each side of the trimmed longitudinal edges of the coil. Acceptance limit for laminar imperfection in the longitudinal edges of the coil shall be as per Table E.9 (New) of this specification. Disposition of defects shall be as per clause E.5.6 of this specification. Table 2 of ISO 10893-9 stands replaced by Table E.9 (New) of this specification.Table E.9 - Acceptance criteria for laminar imperfection in coil/ pipe body (New)
