California ICC UST Inspector Practice Exam

What qualification is least likely expected from a cathodic protection tester?

1. Experience in soil resistivity

2. Experience in structure-to-soil potential

3. Cathodic protection manufacturer training certificate

4. Current certificate from the National Association of Corrosion Engineers

The correct answer is: Cathodic protection manufacturer training certificate

The expectation for qualifications in cathodic protection testing encompasses a range of technical knowledge and practical experience relevant to the field. Among the listed qualifications, the requirement of a cathodic protection manufacturer training certificate is less likely to be a standard expectation compared to the other options. Experience in soil resistivity is critical for understanding how corrosion affects buried structures, as it helps in assessing the effectiveness of cathodic protection systems. Knowledge of structure-to-soil potential is equally essential, as it provides insights into the electrical potentials acting on a structure and the need for protective measures. Both of these experiences are fundamental to a cathodic protection tester's ability to effectively evaluate and implement corrosion prevention measures. Conversely, while having a manufacturer's training certificate can be beneficial, it is not universally necessary across all situations or projects. The focus tends to lie more heavily on direct, hands-on experience related to corrosion prevention, measurements, and analysis rather than adherence to the specific training offered by manufacturers. Thus, while useful, the manufacturer's certificate may not be as critical a qualification as the others mentioned.
