Standard Test Method for Time to Failure of Pressure Sensitive Articles Under Sustained Shear Loading

SIGNIFICANCE AND USE
This test method measures the cohesive strength of the adhesive on a pressure sensitive article. The time to failure can predict end use properties of pressure sensitive articles such as edge ooze from cold flow; trimming, slitting and die cutting quality; telescoping in tapes; ability to seal packages; and vertical holding power.
This test method is suitable for quality control, development and applications testing.
If the adhesive is not already coated, the adhesive can be coated on smooth, clear polyester (PET) film backing 0.05 mm [0.002 in.] thick. The recommended dry adhesive thickness is 0.025 mm [0.001 in.].
Humidity has a strong effect on time to failure for many pressure sensitive articles. Therefore, humidity should be controlled in accordance with 8.1.2.
SCOPE
1.1 This test method covers the ability of a pressure sensitive article (for example, tape, label, sticker, etc.) to remain adhered to a stainless steel panel under a constant load applied parallel to the bonding surface of the pressure sensitive article.
1.2 Values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents, therefore, each system must be used independently without combining values in any way.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
