The EN ISO 7439:2014 is a technical standard that specifies the requirements for non-magnetic metallic coatings on ferromagnetic substrates. It provides guidelines for assessing the thickness and adhesion of such coatings, which are used in various industries to enhance the durability and performance of ferromagnetic materials.
Scope and Purpose
The primary purpose of EN ISO 7439:2014 is to ensure that the non-magnetic metallic coatings meet the required quality standards. The standard defines the testing methods, measurement techniques, and acceptance criteria for assessing the coatings' characteristics. It covers a wide range of metallic coatings, including those made from zinc, tin, chromium, and nickel.
Testing Methods
EN ISO 7439:2014 outlines several testing methods to assess the thickness and adhesion of non-magnetic metallic coatings. These include destructive tests, such as cross-cut and bend tests, which evaluate the coating's ability to adhere to the substrate. Non-destructive tests, such as magnetic induction and eddy current measurements, are also specified to determine the coating thickness.
Benefits and Applications
Complying with EN ISO 7439:2014 offers numerous benefits. First, it ensures that the non-magnetic metallic coatings effectively protect the ferromagnetic substrate against corrosion, wear, and other environmental factors. Second, it guarantees proper adhesion between the coating and the substrate, preventing delamination or peeling. Industries such as automotive, aerospace, electronics, and construction heavily rely on these coatings to enhance the durability and functionality of their products.
