This standard gives procedural instructions for qualification testing of thermal sprayers. It defines essential requirements, ranges of qualification, test conditions, acceptance requirements and certification for qualification testing of thermal spray performance. During the qualification test the thermal sprayer shall be required to show adequate practical experience and job knowledge of thermal spraying processes, materials and safety requirements for which he is to be qualified; information on these aspects is given in Annex A. This standard should be used when the thermal sprayer s qualification is required by the standard, the purchaser, by inspection authorities or by other organisations. The thermal spraying processes referred to in this standard include those spraying processes which are designated as manual or mechanized. The test for mechanised application includes the use of automatically controlled thermal spraying e.g. robotics, scan units etc. The certificate of qualification testing is issued under the sole responsibility of the examiner or test body.
