The incredible work of W Abrasives' engineers and R&D department allowed the WA Clean device to obtain ISO Committee approval.
The WA CLEAN device uses analytical colorimetry, which the ISO Technical Report ISO / TR 22770 describes as a method to support visual assessment of preparation grades, as described in ISO 8501-1. The analytical colorimetry method is based on CIELAB color components as are defined in ISO 11664-3.
WA Clean is an exclusive technology developed by W Abrasives. This tool makes it possible to measure cleanliness of an object, thanks to the colorimetry process.
