Inspection and Assessment of Below Grade and Groundline Corrosion on Weathering Steel on Electrical Transmission and Distribution Structures - Item No. 21433
NACE SP21433
Organization:
NACE - NACE International
Year: 2019
Abstract: This standard provides requirements to: (1) help utilities identify structures that may be at a high risk for below- grade corrosion; (2) excavate and inspect the selected structures; (3) categorize the condition of structures based on corrosion degradation; (4) prioritize structures requiring additional inspection based on those findings; and (5) help identify next steps as required.
This NACE/IEEE joint standard is limited to the inspection and assessment of weathering steel transmission towers, poles, substation structures, and other similar structures.
It does not address the specific inspection of concrete foundations, above-grade attachment points, or guy anchors.
In addition, this standard does not provide procedures regarding repair and/or replacement of these same types of structures.
This standard addresses general and localized corrosion.
This standard does not provide specific pass/fail criteria.
Pass/fail criteria are often determined by structural strength considerations, which are beyond the scope of this corrosion-related standard
