The standard BS ISO 21164-2018 Metal and Miscellaneous inorganic coatings. DC magnetron sputtering roller coatings for engineering purposes. Determination of coating adhesion specifies the method for determining the adhesion of DC magnetron sputtering silver coatings for engineering applications. The standard evaluates the durability and stability of coatings in practical applications by testing their adhesion to the substrate. Adhesion testing is an important step in ensuring that coatings do not peel or break during use. The standard details the applicable test methods, operating steps and required equipment, including disbonding tests and Miscellaneous related test techniques. This standard helps to improve the reliability of roller coatings in industrial applications, especially in the fields of electronic, Optical inspection and anti-corrosion coatings that require high adhesion.
