This International Standard specifies methods for the measure-ment of specular reflectance and specular gloss of flat samples of aluminium or anodized aluminium and its alloys using geometries of 20° (method A), 45° (method B), 60° (method C) and 85° (method D), and of specular reflectance by an additional 45° (method E) employing a narrow acceptance angle. These methods are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but then only for similar colours.

1 This International Standard specifies requirements for nickel plus chromium and for copper plus nickel plus chromium electrodeposited coatings that are applied to iron, steel, zinc alloys, copper and copper alloys, and aluminium and aluminium alloys to provide an attractive appearance and corrosion resistance. Several classes of coatings are provided that differ in thickness and type and guidance is given in selecting the coating class appropriate to the service conditions to which the coated product will be exposed. 2 This International Standard does not specify the surface condition required by the basis metal prior to the coating pro-cess. 3 This International Standard is not applicable to coatings on sheet, strip or wire in the unfabricated form nor to threaded fasteners or coil springs. NOTES 4 ISO 4526 and ISO 6158 specify requirements for coatings of nickel and chromium used for engineering purposes. 5 Requirements for similar coatings, except for the absence of a top-coat of chromium, that can be used for appearance and protection are specified in ISO 1458.

This International Standard specifies requirements for electro-plated coatings of zinc on iron or steel except for coatings applied: a) to sheet, strip or wire in the unfabricated form; b) to close-coiled springs; c) for other than protective or decorative purposes. It includes information to be supplied by the purchaser to the electroplater and requirements for heat treatment, both before and after electroplating. The coating thickness that can be applied to threaded com-ponents may be limited by dimensional requirements, including class or fit. Attention is drawn to ISO 4042, which specifies the maximum thicknesses that can be applied to standard threads.

This International Standard specifies a coulometric method by anodic dissolution for measuring the thickness of metallic coatings. Typical combinations of coatings and substrates that can be tested by this method are given in table 1. Other combinations may be tested with electrolytes in current use (see annex B), or new electrolytes may be developed for them, but, in both cases, it is necessary to verify the suitability of the complete system. The method is also applicable to multi-layer systems, for example Cu/Ni/Cr (see also 8.6). This method may be used to measure the thickness of coatings applied by various means, if due account is taken of special features, such as the presence of an alloy layer. In some cases, the presence and thickness of diffusion layers can also be measured. It can also be used to measure the thickness of coatings on cylindrical specimens and wires (see 8.8).

This International Standard specifies requirements for elec-troplated coatings of tin-lead alloy containing between 50 % (mlm) and 70 % (m/m) of tin (see 10.3). A classification scheme is included by which the nature of the basis metal and the coating composition, within these limits, can be defined and which also contains provision for flow-melting and bright deposited coatings. The coatings are intended for use on both ferrous and non-ferrous basis metals and also on printed circuit boards. It does not apply to a) threaded components; b) bearing overlays; c) coatings on sheet, strip or wire in unfabricated form, or of articles made from them; d) electroplating of steels with tensile strength greater than 1 000 MPa11 (or of corresponding hardness), because such steels require hydrogen embrittlement relief (see 8.2).

This International Standard defines the characteristic properties and specifies methods of test of coatings obtained by the spraying of zinc and aluminium for the general purpose of corrosion protection, for which these metals are suitable. It deals firstly with the definition, classification and symbols for these coatings, in relation to their thickness. It then specifies their characteristic properties : thickness, appearance and adhesion. Finally, it lays down the methods of test which make it possible to check these properties.

This International Standard applies to electroplated coatings of not less than 99,5 % of tin on steel (or iron), and copper or copper alloys. It also applies to coatings brightened by fusion after electrodeposition, the process being known as flow-brightening (or flow-melting). It does not apply to — coatings applied to machine screw threads (with tolerance); — coatings applied to sheet, strip or wire in the unfabricated form, or to coil springs. This International Standard does not specify the surface condition of the basis metal prior to piating; agreement on the degree of roughness which is acceptable shall be reached between the interested parties.

1 This International Standard specifies general methods of measuring the ductility of metallic coatings of thickness below 200 μm prepared by electroplating, autocatalytic deposition or other processes (see the note). The methods of measuring the ductility of metallic coatings can be divided into two main categories: — tests on unsupported foils (separate from the sub-strate); — tests of coatings on substrates. NOTE - When specific methods of testing are included in Inter-national Standards for individual coatings, they should be used in preference to the methods described in this International Standard and should be agreed upon beforehand by the supplier and the purchaser. 2 In the testing of unsupported foils separate from the substrate (see figure 1), the foils may consist of one or more metallic layers, therefore it is possible to measure the ductility of composites and to determine the influence of individual layers on overall ductility. Methods of testing of unsupported foils are described in clause 3. Methods of producing foils for testing are discussed in annex A. 3 In the testing of coatings on substrates (see figure 2), it is especially important to determine the exact point of crack initiation of the top layer. Attention is drawn to different methods of discerning this point, by normal or corrected to normal vision or with a lens. See the guidance in the individual methods. These methods can also be used to detect embrittle-ment of the substrate that may have resulted from the coating process. Methods of testing of coatings on substrates are de-scribed in clause 4. 4 Although ductility is a property of the material and in-dependent of the dimensions of the test piece, thickness of the coating may have an influence on the value of linear elongation (△///0). 1.4.1 Very thin layers have different properties as the build-up of the initial layers will be influenced by the properties of the substrate (epitaxy). High internal stresses may be incorporated into the initial layers and these may effect ductility. 1.4.2 It is essential that the test piece have uniform thickness, as thinner spots will give rise to premature cracking. Also, thecurrent density is lower at thinner parts and higher at thicker parts of electroplated test pieces; in this way current density differences may result in different ductilities. The current density applied should be maintained as uniform as possible over the test pieces, and its value reported.
