hot scratch test

The Honda Hot Scratch Test is a special method for testing the adhesion strength of coatings on plastic parts. The samples to be tested are first deliberately damaged, then heated to 30 °C for more than 80 minutes and then scratched with a linear tester and a standardized blade.

The resulting damage to the coating is assessed in accordance with the standard HONDA 7710Z-TVA-9000 6-14: 2015-11.
