Paint film thickness
This test method, for which RENAULT has delivered self-approval to SERCOVAM, involves determining the thickness of a single- or multi-layer coating to the nearest micron.

A cross-section through the test sample is embedded in a resin.

Measurements are then made using a microscope fitted with a digital camera to produce precise images of the coats or films.

Compliance with standard NF T 30-123 (method A) guarantees the validity of this examination. It is one of the requirements specified by RENAULT for paint coatings on external plastic bodywork parts.
