Said limit, which is set at 0.5 g/cm²/ week, is mentioned in all the standards specifically relating to such products. Since the harmonized standards were published in the Official Journal of the European Community on July 20th 1999, the deadlines are: 20 January 2000: since this date, member states have been obliged to transpose the content of the harmonized standard into their respective national legislation, since 6 months had passed since the date of the standard's publication; 20 July 2000 : since this time, no manufacturer or importer has been allowed to release products that do not comply with the directive onto the market; 20 July 2001: since this date, the sale or transfer to the end user of products that do not comply with the directive has been forbidden. The sequence of tests that the products must undergo to verify how much nickel they release in compliance with the harmonized standards EN 1810:1998, EN 1811:1998, EN 12472:1998, can be divided into three stages: a treatment that simulates wear and tear in normal usage; a chemical conditioning that simulates the release of nickel ions to the user's skin due to perspiration quantitative analysis of the concentration of nickel in the extractor solution (synthetic perspiration) by atomic absorption spectrometry (or a similar technique). In order to recreate a totally nickel-free electrochemical coating of at least 10, which is needed to ensure an effective barrier against the nickel contained in the substrate, copper is the most plausible solution because it also has a cost similar to that of nickel but, unfortunately, it also poses certain other problems by comparison with nickel: - it is an excellent leveler, but not a very good lustering agent; - s- if it is not adequately fixed, it tends to migrate towards the surface and cause oxidation. That is why the copper has to be covered with a coating that lends the object luster and forms an effective barrier layer. The most suitable coatings are Palladium and Bronze. Palladium has been the most often used coating for nickel-free applications in the past, but it tends to become contaminated easily and today it is no longer a feasible option because of the high cost of the metal. It could consequently be said that the ideal protective layer for copper today is a deposit of "white bronze", which presents the following advantages in particular: an appearance identical to a deposit of palladium copper migration is totally prevented good corrosion resistance it gives the substrate the luster typical of nickel it is easy to "strip" in the event of error (unlike palladium) it is inexpensive Process Description Additives Working conditions : BRONZE-PLATING E/R Electrolytic procedure for depositing a very bright and very leveling alloy of copper-tin-zinc, in yellow (even up to considerable thicknesses) or white (for medium-to-low densities); the bronze-plating bath has found an important application in the decorative sector (costume jewelry, spectacle frames). The bronze deposit guarantees the most valid alternative to nickel deposition; it has its own luster and a corrosion resistance comparable with that of nickel. The white bronze deposit can be left as a finishing layer without posing any corrosion problems, or it can be coated, depending on your needs and requirements, with an adequate thickness of a precious metal.
