Standard Test Method for Instrumental Evaluation of Staining of Vinyl Flooring by Adhesives

Importancia y uso:

5.1 Certain substances in adhesives may cause discoloration of vinyl flooring. This test method provides a means of measuring the discolorations that may occur in the vinyl as a result of contact with these adhesives. Vinyl flooring specimens, either contacting or not contacting the adhesive, are exposed to heat and UVA light to accelerate discoloration. By means of colorimeter or spectrophotometer, color differences between exposed specimens are accurately measured. Therefore, instrumental evaluation rather than personal subjective evaluation is used to determine the amount of discoloration an adhesive may produce in vinyl flooring. This test method does not attempt to simulate or duplicate the heat and sunlight conditions that may impact vinyl floor coverings while in service.
