• Provides detailed reporting requirements for test results, supporting reproducibility and traceability

Who Should Comply:

• Pipeline operators and owners (maintenance, integrity, safety managers)
• Laboratory technicians and corrosion specialists
• Equipment suppliers and coating developers
• Regulatory agencies mandating periodic corrosion assessments

Practical Implications & Notable Features:

• Enables accurate risk assessment of internal corrosion, helping operators develop effective inspection and maintenance programs
