ASTM D3330 test methods are used to assess the uniformity of pressure-sensitive adhesive tape adhesion between rolls or production lots. Test Method A measures peel adhesion; Test Method B measures single-coated tape adherence; Test Method C measures double-coated tape adherence; and Test Method D measures the adherence of the release liner to the adhesive.
ASTM D3330 Standard Test Method
ASTM D3330 covers the measurement of the peel adhesion of pressure-sensitive tapes and may not be appropriate to test tapes having relatively stiff backings, stiff liners, or backings showing high stretch at low forces.
| Test Method A | The force required to peel is measured by applying a strip of tape to a test panel and peeling it at a 180° angle in Test Method A. |
| Test Method B | The peel adhesion of single-coated tapes is tested in Test Method B by applying them to a rigid panel and applying them to the backing. |
| Test Method C | In Face adhesion, a strip of 0.025-mm thick polyester film is used to adhere double-coated tape to a stainless-steel panel, liner side up. In liner adhesion, a stainless-steel panel is used to apply double-coated tape adhesive, with the liner side up. |
| Test Method D | The tape is adhered to a standard steel test panel with the liner side up, and the liner is peeled from the adhesive. |
| Test Method E | The adhesion of adhesive transfer tapes is measured by adhering the tape to a standard panel, removing the liner, and applying the tape to a strip of polyester film. |
| Test Method F | A strip of tape is applied to a test panel with controlled pressure, and it is peeled at a 90° angle at a specified rate. |
