ISO 21164:2018 describes the test methods used in evaluating the adhesion of DC magnetron sputtered silver coatings for diverse engineering applications such as electrical, electronic, and optical components. These are not used for decorative purposes but rather for functional reasons. The standard emphasizes the significance of substrate preparation, although it is silent on what surface conditions are needed. Flat objects and sheets are within its scope, whereas non-fabricated forms. These coatings are functional rather than decorative and their quality is affected by the underlying material used, even though they are not intended to specify the method of preparing substrates. It refers to coatings on plane surfaces and sheets.
ISO 21164:2018 framework
Quality and performance standards are kept up to date in such a way that for maintaining floor adhesion in different fields of technology, easy adherence assessment requires a systematic and standardized design based on ISO 21164:2018 adherence. A guide that enables professionals using these coatings to carry out their coating tests correctly at every point in time with precision, torrentially employing ISO 21164:2018. Being in line with ISO 21164:2018 allows for compatibility through adherence
Certifications related to ISO 21164:2018
ISO 21164:2018 alone does not certify anything but only provides specifications and measuring instructions for the bond adhesion values of DC magnetron sputtered silver coatings. Usually, to obtain a certificate, producers undergo an assessment conducted by an independent testing and certification organization that employs ISO 21164:2018 as its parameter. Professionals in the metallic as well as inorganic coating areas find certifications such as CCI by NACE International and SCT, which is offered by ACA, to be necessary. Other areas, like adhesion testing, are contained too. While at the same time including other factors that involve quality management. Engineers certifying bodies, for instance, AESF, have specific certifications like CEF and CMF that pay attention to the field of electroplating. To make sure that innovative systems are maintained within specific industries, these qualifications will confirm competence
Other Tests related to ISO 21164:2018
The ISO 21164:2018 test is related to ISO 1518-1:2019, which determines the scratch resistance of single coatings or multi-coat systems, and ISO 2409:2020, which evaluates the resistance of coatings to separation from substrates.
