The work of preparing International Standards is
21、 normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part
22、 in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particul
23、ar the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this
24、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.is

28、ermal spraying depends on the skill, operation of the spray equipment and job knowledge of the thermal sprayer.The ability of the thermal sprayer to follow verbal and written instructions and the testing of his/her skill and operation of the spray equipment are therefore important factors in ensurin
29、g the quality of the thermally sprayed product.This document is intended to provide the basis for mutual recognition by examining bodies for qualification relating to thermal sprayers competence in the various fields of application. Tests can be carried out in accordance with this document, unless m
30、ore severe tests are specified by the relevant application standards in which case these can be applied.The thermal sprayers skill and job knowledge continues to be classified as qualified as long as the thermal sprayer works with reasonable continuity on thermal spraying work within the extent of q
