Description / Abstract: GMW3402, 5th Edition, September 2016 - Soil and Cleaner Resistance of Automotive Materials

Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This is a two-part procedure. Part A is used to determine the cleanability of materials after having been exposed to a specific soil and cleaned. Part B measures the ability of the material to resist damage (e.g., color change, surface behavior) from applying specific liquid cleaners to a cloth and rubbing it on the surface. Part B also is used to visually determine if there is a color transfer to the cleaning cloth after having been rubbed on the surface of the material with the liquid cleaner.

Applicability. This procedure is applicable to all materials that may be soiled or cleaned during normal use. The tested material must have an appearance that is acceptable to the customer for appearance and haptics after having been cleaned according to this procedure. For Part A, any ring formation after cleaning is undesirable and should be noted on the report in the comment section of the Material specification
