20、the latest by September 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

24、is document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 14232:2000, Thermal spraying Powders Composition and technical supply conditionsISO 14919:2001, Thermal spraying Wires, rods
25、 and cords for flame and arc spraying Classification Technical supply conditions3 GeneralCoatings may be indicated with the general recommendations for technical drawings. To apply this symbolic representation will make sense in cases, where the thermally sprayed coating is very thin and/or may be b
26、uilt up by several dissimilar coatings one upon another.The symbolic representation shall give clearly all necessary indications regarding the specific coating to be obtained without over-burdening the drawing with notes or showing an additional view or detail enlargement.This symbolic representatio
27、n includes an elementary symbol and one or more supplementary symbols and further complementary indications.If a large number of instructions for producing the coating have to be mentioned, it is recommended to indicate the specific instructions on the drawing or to define them in a separate parts l
28、ist, if applicable (see Figures 6 and 7).4 SymbolsThe elementary symbol shall indicate that this process deals with thermal spraying.The following information shall be given by supplementary symbols: type of coating (bond or top coat); the spraying process and subsequent treatments.The following req
29、uirements may be defined by further additional instructions: the coating thickness needed or the final coating thickness machined, respectively; the spray material to be used; surface condition; post-treatments of coating; a technical specification, which defines requirements necessary to complete t
30、he coating.4DIN EN ISO 12671:2014-07 EN ISO 12671:2014 (E) 5 Position of the symbols on drawingsThe complete symbol shall contain: the designation of the coating (outside the outline of the component); an arrow line; a reference line (continuous line) with the elementary symbol above it; instruction
31、s concerning the mode of coating, spraying process, coating thickness, spray material, surface condition, post-treatments, if applicable.The arrow line and reference line form the complete reference mark. A tail (see Figure 2) can be added at the end of the reference line, to make a separate represe
32、ntation of bond and top coat possible.The reference line shall preferably be drawn parallel to the bottom edge of the drawing, or if this is impossible, perpendicular to it.The symbol for the thermally sprayed coating shall be indicated above the reference line (see Figure 1).Key1 designation of the

In such a case, th
40、e coating will be indicated on the drawing only by a position number (see Figure 6). Any instructions regarding the coating, such as spraying process, coating thickness and its acceptable thickness deviation (especially if coatings consist of bond and top coat), spray material, surface condition, an
41、d post-treatments are to be defined in the parts list or by indicating a specific technical instruction (see Figure 6).8 Instructions when the use of the spray process is protected by a patentIf a coating process shall be applied, but the use is protected by a patent (spraying procedure, spray mater
42、ial, process parameter, etc.), the trade name of this coating process may be indicated analogous to “Coating per special specification” (see Figure 7) as a supplementary symbol in the symbolic representation, or it may be defined via a position number in the pertinent parts list (see Figure 6).6DIN
43、EN ISO 12671:2014-07 EN ISO 12671:2014 (E) 9 Representation and dimensioningThe area of a component to be coated shall be indicated by a broad dashed-dot-line outside the outline of the component on the drawing. Where necessary, the size and position of the range of coating shall be defined by means
44、 of dimensions and tolerances on the drawing.Areas, which are allowed to be coated, (e.g. outside the coating range) are to be indicated by a broad dashed line outside the components outline.Areas, which are not accepted to be coated, are not indicated (see Clause 10).The dimension that locates the
45、coating in relation to the front face of the work piece shall appear on the drawing only.The dimensions of length and/or width shall appear on the drawing only.Whenever a post-treatment is applied, the indication of the roughness tolerances shall be mentioned corresponding to the pertinent standard
46、on the drawing close to the dimension.Instructions regarding coating thickness or thickness of bond and top coat, respectively, are to be indicated together with further instructions in the symbolic representation or in the parts list. The coating thickness shall apply for the indicated condition (e
47、.g. ASP = as sprayed; F = fused, M/C = machined, or in combination: F+M/C = fused and machined).If no further instructions about acceptable deviations of coating thickness are mentioned, the general tolerances shall apply.10 Supplementary instructionsSupplementary instructions may be necessary to de
48、fine further particular characteristics by indicating them either in the symbolic representation or in a separate parts list.Instructions containing specific instructions for execution of the preparation or spray procedure or thermal treatment or special sealing are preferably indicated behind the e
49、lementary symbol for the thermally sprayed coating with the pertinent specification number, or they will be indicated by their position number in the parts list (see Figure 7 and Table 1).For workshop drawings only, a remark for applying masking may be given by a specific sign on areas which are not allowed to be coated (see Figure 5).A remark, restricting the acceptable deviations from the no
