Using the SSPC visual guide can reduce the degree of subjectivity associated with evaluating surface cleanliness. There are a total of 5 Vis guides available.
Vis 1: 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.
Vis 2: 27 color photographs and black/white images illustrating 9 different percentages of corrosion (ranging from 0.03% to 50%) for each of three types of rusting (pinpoint, general and spot rusting). Use of the Guide enables the assessor to characterize both the type and percentage of corrosion present on the surface.
Vis 3: Depicts 7 initial conditions of steel (4 uncoated and 3 degrees of deteriorated coating). Surfaces prepared to 4 levels of cleanliness (hand tool, power tool, commercial grade power tool and power tool to bare metal) over each initial condition are provided. Additional images depicting the restoration of surface profile on previously coated surfaces prepared to bare metal (SSPC-SP 11) are also provided.
Vis 4: Depicts 6 initial conditions of steel (2 uncoated and 4 degrees of previously coated steel). Surfaces prepared to 4 levels of cleanliness (light cleaning [WJ-4], thorough cleaning [WJ-3], very thorough cleaning [WJ-2] and removal to expose bare metal [WJ-1]) over each initial condition are provided. Additional images depicting three levels of rust-back (light, medium and heavy) are also provided.
Vis 5: Depicts 2 initial conditions of steel (rusted; rusted & pitted). Surfaces prepared to 2 levels of cleanliness (SSPC-SP 6/NACE 3 Commercial Blast and SSPC-SP 10/NACE 2 Near-white Blast) over each initial condition are provided. Additional images depicting three levels of rust-back (light, medium and heavy) are also provided.
