Annual CP Test Point Survey

An Annual Cathodic Protection test point survey is a regulated requirement that must be done every 12 months, not to exceed 15 months. JRGO can perform your test point survey to ensure you stay up-to-date with all requirements.

JRGO follows the National Association of Corrosion Engineers (NACE) best practices for evaluation of the performance of cathodic protections system published in Standard SP0169. Specifically, Section 6.2 of this standard addresses what JRGO looks to prove compliance:

For buried steel piping, Section 6.2.2.1 states … “one or more of the following shall apply:

6.2.2.1.1 A negative (cathodic) potential of at least 850 mV (.850 volts) with the cathodic protection applied. This potential is measured with respect to a saturated copper/copper sulfate reference electrode contacting the electrolyte. Voltage drops other than those across the structure-to-electrolyte boundary must be considered for valid interpretation of this voltage measurement.
6.2.2.1.2 A negative polarized potential…of at least 850 mV relative to a saturated copper/copper sulfate reference electrode.
6.2.2.1.3 A minimum of 100 mV cathodic polarization between the structure surface and a stable reference electrode contacting the electrolyte. The formation or decay of polarization can be measured to satisfy this criterion.”
