Nondestructive testing personnel (Level III) must be re-certified at least every how many years?

Nondestructive testing personnel at Level III must be re-certified at least every 5 years to ensure they remain current with the latest standards, techniques, and practices in the field. This time frame is established to maintain a high level of skill and competency, ensuring that personnel are up-to-date with evolving technologies and industry requirements. Re-certification helps to verify that technicians continue to meet the qualifications necessary to conduct testing effectively and accurately, which is crucial for maintaining the integrity and safety of welds in pipelines and related facilities. Regular re-evaluation enhances quality assurance and fosters ongoing professional development in this critical area of welding inspection.
