Advance Coating Practice Test

When you’re dealing with a dispute about mill scale on a project using SSPC SP 10, the right move is to bring the standard into the discussion with the Contractor. SSPC SP 10 defines near-white blast cleaning and sets the acceptance criteria for surface cleanliness after blasting, including how much mill scale should be removed and how to verify it on site. By reviewing the exact language of SP 10 together, both parties share a common reference point and can determine whether the surface meets the required cleanliness level before coating proceeds. This keeps decisions grounded in documented requirements and avoids relying on subjective judgments. If, after reviewing the standard, there’s still ambiguity, then follow the project’s procedures for documenting non-conformance or escalating as defined in the quality plan, but the initial step is to consult the standard with the Contractor.
