Self adhesive tapes. Determination of peel adhesion properties. | Status: Superseded, Withdrawn

1 Scope This document specifies a series of methods for the determination of peel adhesion properties of self adhesives tapes. This document contains:

• — Method 1: Self adhesive tapes – Measurement of peel adhesion from stainless steel at an angle of 180°;
• — Method 2: Self adhesive tapes – Measurement of peel adhesion from its own backing at an angle of 180°;
• — Method 3: Self adhesive tapes – Measurement of peel adhesion of double sided and transfer tapes at an angle 180°;
• — Method 4: Self adhesive tapes – Measurement of adhesion of the liner to an adhesive tape at an angle of 180°.

Annexes A and B specify further variations in the testing protocol according to specific conditions. A guide to the use of these methods is given in Table 1. Table 1 — Methods and annexes Method Angle of peel Temperature of test 23 °C Low temperature Method 1 180° — Annex A Adhesion to steel 90° Annex B - Method 2 180° — Annex A Adhesion to backing 90° Annex B — Method 3 180° — Annex A Adhesion of double sided and transfer tape 90° Annex B — Method 4 180° — Annex A Adhesion of liner 90° Annex B - NOTE 1 These methods provide a means of assessing the uniformity of the adhesion of a given type of self adhesive tape. The assessment may be within a roll of tape, between rolls or between production lots. NOTE 2 Variations in the tape backing and adhesive affect the response. Therefore these methods cannot be used to pinpoint the specific cause(s) of non uniformity. NOTE 3 These test methods may not be appropriate to test tapes having either relatively stiff backings, stiff liners or backing showing high stretch at low forces. These characteristics will result in a high variability for the test response which is not a true indication of the real nature of the adhesive bond.
