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.

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.
