GB/T 30776-2014
Measurement of break strength and elongate at break for adhesive tapes

This standard specifies a systematic method for determining the tensile strength and elongation at break of adhesive tapes, primarily applicable to single-sided and double-sided adhesive tapes. The standard explicitly requires the use of a tension testing machine (i.e., a universal material testing machine) that meets specified accuracy requirements. It details the specimen dimensions, tensile rate (e.g., 300 mm/min), and the steps for calculating tensile strength and elongation at break from recorded results. This method provides a scientific assessment of the mechanical properties of adhesive tapes in the direction of applied force, offering critical guidance for product quality control and application selection.
