ISO 3171 (Automatic Pipeline Sampling) is an international standard. API RP 586 is more focused on refinery and terminal situations where sample system retrofits, safety hazards, and operator training require practical, local guidance. Both are complementary; many engineers use ISO 3171 for fundamental math (e.g., determining sample cycle intervals) and RP 586 for the mechanical design and safety implementation.
