Impact testing shall be performed in accordance with L2CC-00055-SP-8603 / SLCP-86-03 on plate, pipe, fittings, forgings and any associated manufacturing welds, with a nominal thickness in excess of 13mm or Licensor requirements if these are more stringent. Samples shall be taken from test specimens that have undergone the minimum and maximum heat-treatments anticipated during fabrication (including any hot forming operations or intermediate heat treatments performed between 750°F [400°C] and 1,115°F [600°C]) plus two additional PWHT cycles. For custom-made forgings, impact testing shall be performed in three directions (longitudinal, radial and tangential) to demonstrate isotropic toughness properties.
