This European Standard gives guidance on tests used for characterizations of coatings produced by thermal spraying. It is not possible in this document to go into details regarding the different types of coatings and large numbers of coatings due to the fact that all meltable materials can be processed by thermal spraying and that so many and varied thermal spraying processes exist. The tests listed are procedures and test criteria in general use for thermally sprayed coatings. Test methods not mentioned here are only used in special cases or under laboratory conditions. NOTE Continuous further development and technical improvements mean that this standard cannot make any claim to completeness.
