API® (American Petroleum Institute)

Since 1989, API’s Individual Certification Programs (ICP) have provided the petroleum and petrochemical industries with an independent and unbiased way to evaluate the knowledge and experience of technical and inspection personnel. These certification programs are based on the industry-developed standards that are recognized and used with confidence worldwide.

API® certified inspectors and personnel are recognized worldwide as professionals who are fully knowledgeable of the relevant industry inspection codes and standards, and who are capable of performing their jobs in accordance with the latest and most acceptable industry inspection practices.

The minimum qualification requirements for API 510 Pressure Vessel inspector certification are based on the combination of education and experience related to pressure vessels. This experience must have been acquired within the last 10 years while employed by, or under contract with, an authorized inspection agency as defined in API 510.
