Modern Industrial Approach to Qualification of Spray Booths and Laboratory Personnel

Reproducibility, repeatability, and reliability are key words in current development of thermal spraying. This article addresses examples of means and procedures, from an industrial point of view, for use during introduction (or recertification) of new spray equipment and new lab personnel. Modern statistical tools, such as two-sample t-tests, ANOVA-analyses and run charts are being applied and defined rules for acceptance/rejection of new machines and personnel are being discussed. It needs to be pointed out that the article gives an industrial approach, rather than a scientific approach, for securing the quality in a modern spray shop over time.
