Which organization certifies LPI operators in Canada?

• A. CSA
• B. NACE
• C. SNT-TC-1A
• D. NRCan

Answer: (D)

In Canada, the authority that certifies liquid penetrant inspection (LPI) operators is Natural Resources Canada (NRCan). This federal department oversees the national NDT certification framework, ensuring that LPI personnel across provinces meet consistent competency standards and hold credentials that are recognized industry-wide.

Organizations like CSA are primarily standards developers and certifiers for equipment and procedures, not the official national certifier of LPI operators. NACE offers professional NDT certifications mainly focused on corrosion control, not the national LPI operator credential in Canada. SNT-TC-1A is a widely used recommended practice that guides how employers structure qualification and certification of NDT personnel, but it is not a certifying body itself. So NRCan is the appropriate choice because it serves as the official national certifier for LPI operators in Canada.
