ISO 2178 Magnetic Method Coating Thickness Testing
The ISO 2178 magnetic method of coating thickness testing is a non-destructive technique that measures the thickness of metallic coatings on ferromagnetic substrates. This service is particularly valuable for industrial manufacturing and processing, where quality assurance plays a critical role in maintaining product integrity.
During this process, a magnetic field is generated by passing an electric current through a coil placed beneath the coating. The interaction between the magnetic flux and the magnetic properties of the coating induces eddy currents that create an opposing magnetic field, which in turn generates a voltage detectable by a probe. This voltage directly correlates to the thickness of the coating.
Industrial coatings are used across various sectors such as automotive, aerospace, construction, and marine industries. The quality of these coatings is crucial for preventing corrosion and ensuring long-term durability. By using ISO 2178 magnetic method testing, manufacturers can ensure that their products meet strict specifications and regulatory requirements.
The test procedure involves several steps:
- Preparation of the sample by cleaning and degreasing it to remove any contaminants that may interfere with the measurement.
- Application of the magnetic field using a probe, which measures the voltage generated in relation to coating thickness.
- Evaluation of the results against specified acceptance criteria.
The ISO 2178 method is widely used due to its simplicity and efficiency. However, it has some limitations, primarily related to the type of substrate material. It can only be used on ferromagnetic substrates like iron or steel. For non-ferrous metals such as aluminum, alternative methods must be employed.

The accuracy of ISO 2178 testing is determined by several factors, including the type of substrate, the magnetic permeability of the coating, and the presence of other ferromagnetic materials in the vicinity. Despite these limitations, this method remains a standard for many applications where it can be used effectively.
The results of ISO 2178 testing are crucial for ensuring compliance with international standards such as ASTM D6432-09, which specifies the use of magnetic induction for coating thickness measurement on non-magnetic substrates. Compliance with these standards is essential for maintaining product quality and safety across various industries.
