Scope

What is ISO 23458 about?    ISO 23458 discusses standards for CVD ceramic coatings. ISO 23458 specifies a test method for determining thermal expansion coefficient up to 2 300 K and the residual stress of chemical vapour deposition (CVD) ceramic coatings (thickness > 0,03 mm) at room temperature. Procedures for test piece preparation, test modes, heat rate, data collection, property calculations and reporting procedures are given.   ISO 23458 applies to CVD ceramic coatings on metal or ceramic substrates. This test method can be used for material research, quality control, characterization and design data-generation purposes.   Who is ISO 23458 for? BS ISO 23458:2020 history
