10、mmittee. It is identical with the 1982 edition of ISO 1463 “Metallic and oxide coatings Measurement of coating thickness Microscopical method”, which was prepared, with the active participation and approval of the United Kingdom, by Subcommittee 2, Methods of inspection and co-ordination of test met
11、hods, of Technical Committee 107, Metallic and other non-organic coatings, of the International Organization for Standardization (ISO). This Part of BS 5411 supersedes BS 5411-5:1976 which is now withdrawn. In 1994 the European Committee for Standardization (CEN) accepted ISO 1463:1982 as European S
12、tandard EN ISO 1463:1994. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN ISO 1463 and any reference to BS 5411-5 should be read as a reference to BS EN ISO 1463. The first edition of this Part of this British Standard differed in a number of respe
13、cts from the first edition of ISO 1463. in the second edition of ISO 1463, dated 1982, many of the technical differences have been removed and those that remain are considered acceptable by the committee concerned. Accordingly, ISO 1463:1982 has been adopted for this edition of this Part of this Bri
14、tish Standard. This edition of BS 5411-5 differs from the previous edition in its editorial layout and also in the following principal respects. a) Information on the factors relating to the measuring accuracy has been added. b) A clause in the previous edition dealing with sampling has now been rem
15、oved, as such information is expected to be included in the specification or other document referring to this Part of this British Standard. c) The guidance, given in Annex A, on the preparation and measurement of cross-sections has been expanded. d) In Annex B, the table of etchants has been brough
16、t up to date. WARNING. This Part of this British Standard calls for the use of substances and/or procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safet
17、y at any stage. In particular, attention is drawn to the need to take appropriate precautions in the preparation, use, handling and disposal of the etching solutions given in Annex B and also their individual components, in connection with the etchant solution B.7, given for the first time in this P
18、art of this British Standard, it should be noted that aqueous hydrofluoric acid is toxic, highly corrosive and attacks skin, eyes, and glass. Prevent contact with eyes, skin and clothing or inhalation of fumes. Wear rubber protective clothing of adequate size and full head and face protection when h
19、andling the material. Carry out all operations involving its use in an effective fume cupboard. Users of hydrofluoric acid are advised to consult appropriate literature for more detailed recommendations. Terminology and conventions. The text of the International Standard has been approved as suitabl
20、e for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use
21、a full point on the baseline as the decimal marker. Where the words “International Standard” appear, referring to this standard, they should be read as “Part of this British Standard”.

22、O 1463:1995 BSI 03-2000iii The lower case “l” has been used as an abbreviation for the litre. In British Standards it is current practice to use a capital “L” as the abbreviation for the litre. Additional information. With reference to Annex B, water complying with BS 3978 “Water for laboratory use”
23、 is suitable and the reagents used should be of analytical quality. BS 871 “Specification for abrasive paper and cloth” gives requirements for, and grading of, abrasive papers and cloths for both technical and general purpose products. A British Standard does not purport to include all the necessary
24、 provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

37、1:00 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 1463:1994 BSI 03-20003 1 Scope and field of application This International Standard specifies a method for the measurement of the local thickness of metallic coatings, oxide layers, and porcelain or vitreous enamel coatings, by the microscopical
38、 examination of cross-sections using an optical microscope. Under good conditions, when using an optical microscope, the method is capable of giving an absolute measuring accuracy of 0,8 4m; this will determine the suitability of the method for measuring the thickness of thin coatings. 2 Reference I
39、SO 2064, Metallic and other non-organic coatings Definitions and conventions concerning the measurement of thickness. 3 Definition local thickness the mean of the thickness measurements, of which a specified number is made within a reference area (See ISO 2064.) 4 Principle Cutting out a portion of
40、the test specimen, mounting it, and preparing the mounted cross-section by suitable techniques of grinding, polishing, and etching. Measurement of the thickness of the coating cross-section by means of a calibrated scale. NOTEThese techniques will be familiar to experienced metallographers, but some
41、 guidance is given in clause 5 and in Annex A for less experienced operators. 5 Factors relating to the measuring accuracy 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 accura
42、te measurement. (See Annex A, clause A.4.) 5.2 Taper of cross-section If the plane of the cross-section is not perpendicular to the plane of the coating, the measured thickness will be greater than the true thickness. For example, an inclination of 10 to the perpendicular will contribute a 1,5 % err
43、or. 5.3 Deformation of coating Detrimental deformation of the coating can be caused by excessive temperature or pressure during mounting and preparation of cross-sections of soft coatings or coatings melting at low temperatures, and also by excessive abrasion of brittle materials during preparation
44、of cross-sections. 5.4 Rounding of edge of coating If the edge of the coating 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, polishi
45、ng or etching. It is usually minimized by overplating the test specimen before mounting. (See Annex A, clause A.1.) 5.5 Overplating Overplating of the test specimen serves to protect the coating edges during preparation of cross-sections and thus to prevent an erroneous measurement. Removal of coati
46、ng material during surface preparation for overplating can cause a low thickness measurement. 5.6 Etching Optimum etching will produce a clearly defined and narrow dark line at the interface of two metals. Excessive etching produces a poorly defined or wide line which may result in an erroneous meas
47、urement. 5.7 Smearing Improper polishing may leave one metal smeared over the other metal so as to obscure the true boundary between the two metals. The apparent boundary may be poorly defined or very irregular instead of straight and well defined. To verify the absence of smearing, the coating thic
48、kness should be measured and the polishing, etching, and thickness measurement repeated. A significant change in apparent thickness indicates that smearing was probably present during one of the measurements. 5.8 Magnification For any given coating thickness, measurement errors generally increase wi
49、th decreasing magnification. If possible, the magnification should be chosen so that the field of view is between 1,5 and 3 times the coating thickness. 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 per cent are not unrealistic unless the scale has been calibrated or has been certified by a responsible supplier. A generally satisfactory means of calibration is to assume that the stated length of the full scale is correct, to measure ea
