Surface Roughness


Roughness is defined as fine irregularities in the surface texture, which results from the inherent action of a production process. In protective coating applications there is a requirement to measure surface roughness to ensure a surface quality suitable for coating application.

Surface roughness measurements can also indicate processing stages that cause an increase in surface roughness, which may impact upon a products final suitability for application.

Aerofin Laboratories can conduct Surface roughness testing. testing specifications include:

  • BATS 3211.
  • ASTM D7127.
  • ISO 4287.

Aerofin Laboratories can evaluate process suitability
and effectiveness for your chosen application.
