Quality

This standard is the official version in English and Italian of the European standard EN ISO 4527 (edition May 2003). The standard specifies requirements and test methods for autocatalytic chemical coatings of nickel-phosphorus alloy layers on metal substrates from aqueous solutions. This standard does not apply to autocatalytic chemical coatings of nickel-boron alloy, matrix composites of nickel-phosphorus and ternary alloys.

This standard is the official English language version of the European standard EN ISO 3497 (edition December 2000) and takes into account the corrections introduced 16 May, 2001. The standard specifies the methods for measuring the thickness of metal coatings for X-ray spectrometry. They allow for the simultaneous measurement of coating systems up to three layers and for the determination of the mass per unit area. Knowing the density of the coating material, the measurement results can be expressed as the coating thickness. The measurement interval, for the individual coating materials, is dependent on the accuracy of the method for the specific material and can vary depending on the instrumentation and the measurement procedure used. The standard does not relate to the protection of people using x-rays.

The standard specifies a method for the non-destructive measurement of the thickness of non-magnetic coatings on magnetic substrates by means of a probe or a tool with integrated probe placed directly on the coating to be measured.
The method can also be applied to the measurement of magnetic coatings on magnetic substrates or other materials (see the UNI EN ISO 2361).
Compared to the previous version, the standard has not been updated in a major way.

The Italian version of the European standard EN ISO 2819 (Edition October 1994) transposing the text of the homonymous international standard ISO 1980. It describes the test methods for the adhesion of electrolytic and autocatalytic coatings (carried out by chemical means). It is limited to qualitative tests. In the standard, no methods are described that provide a quantitative measure of adherence because, as special equipment and considerable skill from the operator are necessary, these are not suitable as a quality control for the current production. Some of these quantitative tests may, however, be useful in research and development work.

This standard is the official version of the European standard EN ISO 27830 (edition August 2003). The standard specifies the technical requirements of metallic and inorganic coatings in order to develop coherent technical standards. It establishes a standard format for the description of the coatings. It applies to international standards of coatings by electrodeposition, autocatalytic and vapour deposition.

This standard is the official version in Italian of the European standard EN ISO 9220 (edition October 1994). The standard specifies a method for measuring the local thickness of metal coatings through the examination of cross sections by means of a scanning electron microscope (SEM). It can be used for thicknesses up to several millimetres, but usually it is more practical to use an optical microscope (see EN ISO 1463) when its method permits.

This standard is the official version in English and Italian of the European standard EN ISO 1463 (edition May 2004). The standard specifies a method for measuring the local thickness of metallic coatings, oxide layers and porcelain enamels by examination of their sections with an optical microscope.

This standard is the official version of the European standard EN ISO 3882 (edition April 2003) and takes into account the corrections introduced 16 July, 2003. The standard provides an overview of methods for measuring the thickness of metal and organic coatings on metallic and non-metallic substrates. It is limited to tests already specified or to be specified in the rules, and excludes certain tests that are used for particular applications.

This standard is the official version in English of the European standard EN ISO 6507-1 (edition December 2005). The standard specifies the Vickers hardness test method of the metallic materials for the three different test load ranges. The Vickers hardness test is defined by the lengths of the diagonals of the footprint of between 0.020 mm and 1.400 mm

This standard is the official version of the European standard EN ISO 9227 (edition May 2012). The standard specifies the equipment, reagents and the procedure for carrying out tests of neutral salt spray (NSS), saline-acetic fog (AASS) and cupro acetic salt mist (CASS), to evaluate the corrosion resistance of metallic materials, with or without permanent or temporary corrosion protection

This standard is the official version of the European standard EN ISO 11474 (edition March 2014). The standard specifies a method for evaluating the resistance to corrosion of metals by means of accelerated external corrosion test in artificial atmosphere with intermittent spraying of a salt solution (Scab test). The method is suitable for comparison tests to optimize the superficial treatment systems

This standard is the official version in Italian of the European standard EN ISO 6988 (edition October 1994). The standard specifies a method for evaluating the resistance to corrosion of materials or products to an atmosphere containing condensed moisture and Sulphur dioxide. The method has been found to be suitable for assessing metal and other non-organic coatings.

This standard is the official version of the European standard EN ISO 10308 (edition January 2006). The rule includes a review of the published methods which have the purpose of detecting the presence of porosity and discontinuity in different types of metal coatings and in colour-conversion coatings or phosphate (including associated organic films) on a given basic metal type.

The standard defines a method to reveal porosity or other discontinuities, during the tests on the metal coatings, which are not affected noticeably by ferricyanide and chloride ions during the trial period and are cathodic in relation to iron and steel. This method is particularly useful for high thickness coatings of hard chrome used for wear resistance

This standard is the official version in English of the European standard EN 12472:2005+A1 (edition June 2009). The standard specifies a method to simulate the accelerated wear and corrosion, to be used for the determination of nickel release from coated items that come into direct and prolonged contact with the skin.

The standard establishes the test methods and migration limits of lead and nickel in the equipment for the preparation and distribution of hot beverages used in commercial establishments and in the community.
