CEN/TC 253 - Self adhesive tapes

This standard specifies the method to measure under specified test conditions the force required to remove an adhesive tape which has been applied to a standard metal surface. This European Standard specifies the method of measurement under specified test conditions, the force required to remove an adhesive tape...

This standard specifies a method to measure the breaking strength of a self adhesive tape when it is subjected to a tensile force sufficient to cause it to break. The breaking strength of adhesive tape is of value as an indication of its uniformity and quality, and its ability to withstand stresses during application and use. The maximum width of adhesive tape tested by this method is 25 mm. For adhesive tapes of this width or less, the breaking strength measured corresponds to that as supplied commercially, with factory-cut edges.

This standard specifies a method to measure the elongation of a self adhesive tape when it is subjected to a tensile force sufficient to cause it to break. The elongation at break of the adhesive tape is of value as an indication if its uniformity and quality, as well as a rough indication of its ability to conform to curved and irregular surfaces. It is usually determined at the same time as the breaking strength.

This standard specifies a method to measure the total thickness of both the backing and adhesive layer comprising an adhesive tape. The thickness is a useful factor in defining an adhesive tape and checking its uniformity. It is used in the determination of physical and electrical properties. Since the width of adhesive tape shall be greater than the diameter of the pressure foot on the micrometer, and as this can be up to 12 mm, the method is therefore not strictly applicable to adhesive tapes having a width less than the diameter of the foot.

This standard specifies a method to measure the force required to cause an adhesive tape to slip in shear from a specified metal surface to which the adhesive tape has been applied under standard test conditions, in two conditions of different temperatures 23 °C and 70 °C. An annex A is attached which shall be followed when testing double side adhesive tape.
