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°.AnnexesA and B specify further variations in the testing protocol according to specific conditions.A guide to the use of these methods is given in Table1.Table1Methods and annexesMethodAngle of peelTemperature of test23 °CLow temperatureMethod 1180°—AnnexAAdhesion to steel90°AnnexB-Method 2180°—AnnexAAdhesion to backing90°AnnexB—Method 3180°—AnnexAAdhesion of double sided and transfer tape90°AnnexB—Method 4180°—AnnexAAdhesion of liner90°AnnexB- NOTE1 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. NOTE2 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. NOTE3 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.
