  The standard covers both new fabrication and repair welds, addressing various cracking mechanisms including and Alkaline Stress Corrosion Cracking (ASCC) . Key Technical Requirements coating holiday survey

  1. Conduct baseline condition assessment before commissioning (soil resistivity, coating holiday survey, pipe-to-soil potentials).
  2. Design CP systems to align with expected coating life and predicted current demand; include monitoring test points at regular intervals.
  3. Specify coating application standards, holiday detection thresholds, and acceptance criteria for new construction.
  4. Schedule routine inspections: CP survey annually (or more often in high-risk areas), close-interval testing where anomalies appear, and in-line inspection where feasible.
  5. Use a corrosion management plan with defined KPIs (e.g., percent of test posts within protection criteria, number of coating holidays per mile) and corrective action triggers.
  6. Train personnel in handling, inspection, and safe work practices around CP systems and excavation near live pipelines.
