What is the principal focus of SSPC-SP15 standards?

The principal focus of the SSPC-SP15 standards is on commercial grade power tool cleaning. This standard outlines the procedures and expectations for preparing steel surfaces using power tools, such as grinders and sanders, to remove rust, mill scale, and old coatings. The goal of SSPC-SP15 is to achieve a surface that is sufficiently clean to allow for proper adhesion of new coatings while maintaining a reasonable standard of cleanliness that can be achieved with the tools and techniques available in commercial applications.

The emphasis on using power tools distinguishes this standard from other methods that may involve abrasive blasting or other surface preparation techniques. As such, SSPC-SP15 is particularly relevant in situations where the use of power tools is more practical and economical compared to more intensive surface preparation methods.
