📉 NACE SP0169 -850 mV CSE Polarized Instant-Off Criterion, IR Drop Elimination

Pipeline Pipe-to-Soil Potential Calculator

Model annual pipeline cathodic protection compliance surveys under NACE SP0169 / 49 CFR 192: calculate Copper/Copper Sulfate (CSE) pipe-to-soil potentials, synchronize GPS current interrupters to record true polarized Instant-Off potentials (eliminating soil IR drop errors to verify compliance with the -850 mV polarized potential standard), and CP testing margins.
