The standard does not pass or fail a material. Instead, it provides a relative rating. A lower stain rating means the material is more resistant (easier to clean). A higher rating indicates permanent staining. This allows manufacturers to compare two different formulations directly.
No. This standard is limited to liquid and water-miscible products under dynamic conditions. For solids or non-miscible materials, refer to ASTM E2315 or E2783. astm e2109-01 pdf
ASTM E2109-01 provides a test method for determining the shear resistance (also called "creep resistance" or "holding power") of pressure-sensitive adhesive (PSA) articles — such as tapes, labels, films, and transfer adhesives — under a constant load applied parallel to the bonded surfaces. The standard does not pass or fail a material
The key output is time to failure (in minutes or hours) when the adhesive bond fails cohesively or adhesively under sustained shear stress. astm e2109-01 pdf
This method is essential for predicting long-term performance of PSAs in applications like:
Although ASTM E2109 was updated in 2015 (resulting in the active version ASTM E2109-01(2015) ), the original 2001 version remains widely cited for several reasons:
Important Note: ASTM International strongly recommends using the latest active version (E2109-01(2015) or later). However, if you need the 2001 edition for specific historical or regulatory reasons, you must obtain the authentic ASTM PDF.
