The SSPC surface preparation standard SSPC-SP5 is associated with what?

The SSPC surface preparation standard SSPC-SP5 is specifically associated with white metal blast cleaning. This method is recognized for achieving the highest level of cleanliness by removing all visible rust, mill scale, and other contaminants from the surface of steel. The goal of this standard is to prepare surfaces to ensure optimal adhesion of coatings, leading to better long-term performance and protection of the substrate.

White metal blast cleaning, as outlined in SSPC-SP5, involves using abrasive materials and high-pressure air or water to create a surface that is free of any foreign substances. The standard provides explicit visual pictures to illustrate the desired cleanliness, which aids in ensuring uniformity and consistency across various applications. This level of preparation is crucial for projects that require a pristine substrate, such as when applying protective coatings in harsh environments.

While other options like rust removal or power tool cleaning involve important preparatory processes, they do not specifically denote the complete and thorough cleaning that SSPC-SP5 entails. Therefore, the connection of SSPC-SP5 with white metal blast cleaning is recognized in industry standards as the most rigorous form of surface preparation.
