• Ferrite determination by point counting in accordance with ASTM E562, on a transverse metallographic specimen using the intercept method and a minimum grid size of 25. Fields shall be selected randomly and magnification chosen appropriate to the ferrite lathe size (×500-×1000 is preferred). The root, fill and cap weld metal and HAZ shall be sampled separately. Ferrite levels shall be in the range 35-70% for weld metal and HAZ. Use of automated analysis in accordance with ASTM E1245 shall be subject to Owner review and approval
• Impact testing at the MDMT or 14°F (minus 10°C), whichever is lower in accordance with L2CC-000-55-SP-8603 / SLCP-86-03.
