This calculator provides a quick estimation of coating thickness acceptance criteria according to ISO 19840, based on the specified nominal dry film thickness (NDFT). It also allows roughness profile corrections commonly applied for fine, medium and coarse profiles during coating inspection activities.
This tool is intended for coating inspectors, quality personnel, asset owners, engineering companies, applicators and other stakeholders involved in surface preparation, protective coating application and corrosion protection projects.

Warning: one or more values without correction have been manually modified. The calculation therefore no longer strictly corresponds to the default ISO 19840 criteria.
Minimum and maximum values without correction can be adjusted to reflect specific project specifications.
