The standard you're likely referring to is related to the mitigation of stray-current corrosion.

Scope and Purpose

NACE SP0170 focuses on External Corrosion Direct Assessment (ECDA), a process intended to evaluate whether external corrosion exists on a pipeline and to direct follow-up actions (inspection, repair, monitoring). ECDA complements other integrity management practices (in-line inspection, hydrostatic testing, cathodic protection surveys) and is particularly applied where direct tools (smart pigs) are impractical or as a supplemental method. nace sp0170 pdf 2021

Primary objectives:

• Provide a structured, risk-informed methodology to locate areas likely to have external corrosion.
• Define data requirements, modeling approaches, and validation steps.
• Integrate cathodic protection (CP) data, coating condition, soil properties, and environmental factors into assessment planning.
• Minimize missed defects while optimizing resource allocation for excavation and repair.
