The WA CLEAN is an electronic optical device using as working principle an analytical colorimetry method to support the visual assessment of the surface preparation grades of uncoated steel substrates as defined in ISO 8501-1 or SSPC – VIS 1.
The usage of analytical colorimetry method as support tool for the visual evaluation of the surface preparation grades is described by ISO/TR 22770 document.
The evaluations of the surface preparation grades via visual assessment by using the ISO 8501 – 1, SSPC – VIS 1 reference photographs are now reinforced by figures issued from measurements done with the WA CLEAN device on the initial visually qualified surface preparation grades.
The utilization of the WA CLEAN device makes possible an objective and reliable evaluation of the blast - cleaning grades, independently of any human interpretation. It reads, quantifies and archives the degree of surface cleanliness achieved on your blasted parts.
