What is ISO 2081:2018 Metallic and other inorganic coatings — Electroplated coatings of zinc with supplementary treatments on iron or steel?
ISO 2081:2018 specifies requirements for electroplated coatings of zinc with supplementary treatments on iron or steel. The standard covers the coatings applied to parts such as fasteners, sheet metal parts, wire goods, and small components, which are intended to provide corrosion resistance or to enhance the appearance of the substrate.
The standard specifies the requirements for the coatings, including the thickness of the coating, the adhesion of the coating to the substrate, and the appearance of the coating.
In addition, The standard also specifies the supplementary treatments that may be applied to the coating. Including chromate conversion coatings, phosphate conversion coatings, and other types of organic and inorganic coatings.
ISO 2081 applies to coatings applied by electroplating, which is a process that involves the deposition of a metal coating onto a substrate by electrolysis. The standard applies to coatings applied to iron or steel substrates, but may also be applicable to other metals.
The standard is intended to provide a basis for assessing the performance of electroplated zinc coatings with supplementary treatments on iron or steel, and to ensure that the coatings meet the requirements for corrosion resistance, adhesion, and appearance.
Therefore, The standard is relevant to manufacturers, users, and regulators of coated products, as well as those involved in research and development of surface treatment technologies.
Requirements of ISO 2081:2018
ISO 2081:2018 specifies several requirements for electroplated coatings of zinc with supplementary treatments on iron or steel, including:
Coating thickness: The standard specifies the minimum and maximum thickness of the coating. Which can vary depending on the application and the type of substrate.
Adhesion: The coating must adhere firmly to the substrate, as determined by a specified test method.
Corrosion resistance: The coating must provide a specified level of corrosion resistance, as determined by a specified test method.
Appearance: The coating must have a uniform and consistent appearance, with no visible defects. Such as blisters, pits, or cracks.
Supplementary treatments: The standard specifies the types of supplementary treatments that may be applied to the coating. Including chromate conversion coatings, phosphate conversion coatings, and other types of organic and inorganic coatings.
At last, Testing and inspection: The standard specifies the methods for testing and inspecting the coatings. Including visual inspection, adhesion testing, corrosion resistance testing, and measurement of coating thickness.
ISO 2081:2018 is intends to ensure that electroplated coatings of zinc with supplementary treatments on iron or steel meet specific requirements for thickness, adhesion, corrosion resistance, and appearance. Therefore, the standard is relevant to manufacturers, users, and regulators of coated products. As well as those involved in research and development of surface treatment technologies.
Benefits of this standard
ISO 2081 provides several benefits to the surface treatment and coating industry, including:
Improved corrosion resistance: The standard helps ensure that electroplated coatings of zinc with supplementary treatments on iron or steel provide the required level of corrosion resistance. Which can help extend the life of coated products.
Consistent quality: The standard provides a basis for assessing the performance of electroplated coatings of zinc with supplementary treatments on iron or steel. Which can help ensure consistent quality across different manufacturers and regions.
Clear requirements: The standard specifies clear requirements for coating thickness, adhesion, corrosion resistance, and appearance. Which can help manufacturers and users of coated products understand the performance and limitations of the coatings.
Increased safety: The standard specifies testing and inspection methods to ensure that coated products meet safety requirements. Which can help reduce the risk of accidents and failures.
Finally, International recognition: ISO 2081 is an internationally popular standard. Which can help manufacturers and users of coated products comply with regulations and requirements across different regions and countries.
Who needs ISO 2081:2018?
ISO 2081 is relevant to a wide range of industries and organizations involved in the manufacture, use, and testing of coated products made of iron or steel. So, Some specific groups who may benefit from ISO 2081:2018 include:
Coating manufacturers: Companies that produce electroplated coatings of zinc with supplementary treatments on iron or steel can use ISO 2081:2018 as a guide for quality control. Also, to ensure that their coatings meet specific requirements for thickness, adhesion, corrosion resistance, and appearance.
Product manufacturers: Companies that use coated products made of iron or steel, such as fasteners, sheet metal parts, wire goods, and small components, can benefit from ISO 2081:2018. By ensuring that the coatings on their products meet the required performance standards.
Regulators and inspectors: Government agencies and organizations responsible for regulating the use of coated products in specific industries. Such as automotive or aerospace, can use ISO 2081 as a basis for testing and inspection requirements.
At last, Testing and certification organizations: Laboratories and certification bodies that test and certify coated products for quality and safety can use ISO 2081:2018 as a guide for testing methods and performance requirements.
