NACE SA 2.5 / SSPC SP-10 VS NACE SA 3 / SSPC SP-5?
If you’re navigating the nuances between Brush-Off, White Metal, Near-White, and Commercial blast grades, understanding the differences is crucial. We recommend checking out our video on the four categories of blast and their visual differences on rusted surfaces. The video, “How to achieve SSPC Grades of Blast” clearly demonstrates what you need to know to differentiate between these blast standards.
Surface Cleanliness Disagreements When it comes to disagreements between inspectors and contractors over surface cleanliness, the inspector has the final say. To avoid conflicts and ensure smooth project progression, here are a few tips:
- Clarify Expectations Early: From the start, ensure that both parties clearly understand the surface cleanliness expectations. It’s better to verify these details early on rather than risk losing an entire day of work due to misunderstandings.
- Disagreements on Cleanliness: If a dispute arises, both the contractor and inspector should refer back to their agreed-upon definitions of cleanliness. This typically involves the complete removal of visible rust, paint, contaminants, and mill scale, leaving the metal with a uniform white or grey appearance. If there are inconsistencies, ask the inspector to identify them specifically.
- Addressing Subjectivity: Uniformity can be subjective, but by collaborating closely with the inspector and taking detailed notes, you can ensure that any issues are resolved swiftly and effectively.
