SSPC's most widely used visual reference features over 50 full-color photos of previously coated and uncoated, rusted steel surfaces before and after white metal (SP 5/ NACE 1), near-white (SP 10/NACE 2), commercial (SP 6/NACE 3), industrial (SP 14/NACE 8), and brush-off blast cleaning (SP 7/NACE 4). Appendix photographs show variations in white metal surfaces caused by different metallic and non-metallic abrasives, and by differences in profile depth, angle of view and lighting.
Verification of surface cleanliness after dry abrasive blast cleaning using only the joint written standards prepared by SSPC and NACE can be left to interpretation and result in subjective evaluations and controversy on a project. Using the SSPC visual guide can reduce the degree of subjectivity associated with evaluating surface cleanliness. The SSPC VIS 1 visual guide depicts 7 initial conditions of steel (4 uncoated and 3 degrees of deteriorated coating). Surfaces prepared to 5 levels of cleanliness (Brush-off, Industrial, Commercial, Near-white and White Metal) over each initial condition are provided. Additional images depicting the affect of abrasive type, surface profile and lighting on surface cleanliness evaluations are also provided. Made in the USA.
High quality reference photographs depicting the appearance of both previously unpainted and previously painted and partially reusted hot-rolled carbon steel prior to and after abrasive blast cleaning. Ahora con la Guia de fotografias de Referencia en Espanol.
