ERICHSEN SCRATCH TEST

Erichsen tests are performed with a selection of at least two loads lower and at least two loads higher than the critical load for scratch visibility. The visibility evaluation for the Erichsen test is carried out by obtaining the color information (L, a and b from CIELab theory) using a spectrophotometer. The L values are used to calculate the differences in a brightness between the cross-hatched scratch pattern and the virgin polymer surface, termed as ΔL.
