METHOD AND TOOL FOR SELF-ASSESSMENT ON MATERIAL QUALITY

This method is designed to allow anyone perform a measurement of powder quality based on its color in an easy way. Using a small box for sampling collection and a lid with a specific hole on its surface, the method provides a solution for a fast analysis of powder quality on‐site. It can be used by any person (no special skills needed) and it has been proven to be robust and reliable. The hole is intended to fit with a standard commercial colorimeter. The system creates a flat horizontal surface that can be read by the colorimeter, a dark chamber that allows the measurement to be taken without external influences and a method to keep the focal distance constant, allowing different measurements to be compared among themselves
