Scope:

ASTM D6252-98 is used in quality control, to assure that the label stock has the required peel adhesive value. This test can also evaluate the uniformity of the adhesion of given pressure-sensitive label stock. ASTM D6252-98 can be used to determine the relative bond strength of label stock to varied surfaces of different materials and textures as opposed to the standard stainless steel panel. This test method is not used to test label stocks with either stiff backings or backings with a high stretch at low forces.

Test Procedure:

A strip of label stock is applied to a standard test panel, or other surfaces of interest, with controlled pressure. The strip is peeled from the panel at a 90° angle at a specified rate, while the force required for peeling is measured.

Specimen Size: 

The sample should be approximately 150 mm in length. The specimens should be wider than 12.7 mm but narrower than 25.4 mm. 

If samples are in roll form, three to six outer wraps of label stock are thrown away.

Data:

Peel adhesion of the sample label stock is reported.
