28、 bodies). The work of preparing International Standards is 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
29、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directiv
30、es, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
31、casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1463 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic

33、kness Microscopical method 1 Scope This International Standard describes a method for the measurement of the local thickness of metallic coatings, oxide layers, and porcelain or vitreous enamel coatings, by the microscopical examination of cross-sections using an optical microscope.

It is the responsibility of the user to establish appropriate health and safety practices and to take suitable action to
35、comply with any national and/or local regulations prior to its use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc

ISO 2064, Metallic and other inorganic coatings Definitions and conventions concerning the measurement of thickness 3 Term and definition For the purposes of this document the following term and definition apply. 3.1 local thickness the mean of the thickness
37、 measurements, of which a specified number is made within a reference area 3.4 of ISO 2064:1996 4 Principle A portion of the test specimen is cut out and mounted. The mounted cross-section is prepared by suitable techniques of grinding, polishing and etching. The thickness of the coating cross-secti
38、on is measured by means of a calibrated scale. NOTE These techniques will be familiar to experienced metallographers, but some guidance is given in Clause 5 and in Annex A for less experienced operators.

39、ent uncertainty 5.1 Surface roughness If the coating or its substrate has a rough surface, one or both of the interfaces bounding the coating cross- section may be too irregular to permit accurate measurement. (See A.5.) 5.2 Taper of cross-section If the plane of the cross-section is not perpendicul
40、ar to the plane of the coating, the measured thickness will be greater than the true thickness; e.g., an inclination of 10 to the perpendicular will contribute a 1,5 % error. NOTE B.1 provides guidance on taper cross-section. 5.3 Deformation of coating Detrimental deformation of the coating can be c
41、aused by excessive temperature or pressure during mounting and preparation of cross-sections of soft coatings or coatings that melt at a low temperature, and also by excessive abrasion of brittle materials during preparation of cross-sections. 5.4 Rounding of edge of coating If the edge of the coati
42、ng cross-section is rounded, i.e. if the coating cross-section is not completely flat up to its edges, the true thickness cannot be observed microscopically. Edge rounding can be caused by improper mounting, grinding, polishing or etching. It is usually minimized by overplating the test specimen bef
43、ore mounting. (See A.2.) 5.5 Overplating Overplating of the test specimen protects the coating edges during preparation of cross-sections and thus prevents erroneous measurement. Removal of coating material during surface preparation for overplating can result in a low thickness measurement. 5.6 Etc
44、hing Optimum etching produces a clearly defined and narrow dark line at the interface of two metals. Excessive etching produces a poorly defined or wide line that can result in erroneous measurement. 5.7 Smearing Improper polishing or overplating with a softer metal may cause smearing of one metal o
45、ver the other metal, obscuring the boundary between the coating and the substrate. This problem may be alleviated by repeating the preparation of the cross section of the coated metal until repeatability of the thickness measurement (see A.3 and A.5) is obtained and also by over-plating with a harde
46、r metal. 5.8 Magnification For any given coating thickness, measurement uncertainty generally increase with decreasing magnification. The magnification should be chosen so that the field of view is between 1,5 and 3 the coating thickness. EN ISO 1463:2004 IS:3641 O3002(E) I SO 3002 All irhgts serede
47、vr 3 5.9 Calibration of stage micrometer Any error in calibration of the stage micrometer will be reflected in the measurement of the specimen. Errors of several percent are not unrealistic unless the scale has been calibrated or has been certified by a responsible supplier. A generally satisfactory
48、 means of calibration is to assume that the stated length of the full scale is correct, to measure each subdivision with a filar micrometer, and to calculate the length of each sub-division by simple proportion. 5.10 Calibration of micrometer eyepiece A filar micrometer eyepiece generally provides t
49、he most satisfactory means of making the measurement of the specimen. The measurement will be no more accurate than the calibration of the eyepiece. As calibration is operator dependent, the eyepiece shall be calibrated by the person making the measurement. Repeated calibrations of the micrometer eyepiece can be reasonably expected to have a spread of less than 1 %. The distance between the two lines of a stage micrometer
