QP Accreditation for coating and lining inspection companies

Why attain SSPC QP 5 (now AMPP QP) accreditation?

QP 5 is an accreditation program for inspection companies that focuses on the industrial coating and lining industry. QP 5 evaluates an inspection company’s ability to provide consistent quality inspection of coatings and linings for its clients.

On a fundamental level, QP 5 provides support to both the owner and inspection company by requiring checks and balances that ensure a high level of quality inspection regardless of which individual inspector is working the job site. This is due to inspection service providers adopting quality programs that include regular maintenance training for inspectors, quality and procedural standards, corporate internal auditing of inspection records, and accountability.

    To be certified to QP 5, coating and lining inspection companies must demonstrate company standards in key areas:

    These key areas are evaluated first in form of submittals at the time of application, then confirmed through an impartial on-site audit at the applicant’s headquarters.
    The on-site audit criteria can be found in both the QP 5 application and the Self-evaluation Checklist. AMPP strongly advises using the checklist to be sure all areas are addressed prior to the on-site audit.

    QP 5 background

    The QP 5 standard was approved in 1999 and the current QP-5 program is based on the 2012 revision of the QP 5 standard.
    QP 5 is based on criteria established in the SSPC-QP 5 standard that was developed through a consensus process. The QP 5 standard is available for purchase in the AMPP Marketplace.
