2Expert Interpretation
This in-depth analysis of the 17 adhesion test methods in ISO 2819:2017 — Electroplated and electroless metal coatings on metal substrates — includes qualitative testing techniques such as burnishing, thermal shock, and cross-cut tests. It also covers the compatibility comparison of different coating thicknesses with metal materials, providing a standardized solution for manufacturing quality control.
ISO 2819:2017 specifies qualitative test methods for the adhesion of electroplated and chemically deposited coatings on metal substrates. This standard applies to common metal coatings such as chromium, nickel, and silver, and explicitly excludes quantitative test methods that require specialized equipment.

Non
Tensile Test (4.11)
>125μm
Silver/Gold
Automotive parts case: For nickel-chromium plating with a thickness of 150-300μm, it is recommended to use the following combination:
Added Rockwell-C test (refer to ISO 26443)
Improved the normative requirements for shot peening test of silver coating (Appendix A)
Clarified that the temperature control accuracy of thermal shock test is ±10℃
Implementation suggestions
Automotive parts case: For nickel-chromium plating with a thickness of 150-300μm, it is recommended to use the following combination:
Firstly, perform a non-destructive cross-cut test (4.8)
Sampling is carried out Bend test (4.9) Verification
Additional Thermal shock test (4.12)
Be careful to avoid using the chisel test (4.7) on soft coatings such as zinc and cadmium.
Limitations of the standard
This standard is explicitly not applicable to:
Coating/substrate combinations with similar thermal expansion coefficients
Ultra-thick coatings exceeding 600μm
R&D scenarios requiring precise quantification of adhesion
