This standard primarily specifies the test method for determining the peel strength of high-strength bonded joints using the floating roller method. It is specifically designed to evaluate the peel strength of adhesives between rigid materials and flexible materials, such as rigid metals and flexible metals. The core of the standard involves the use of a tensile testing machine or an electronic tensile testing machine that meets the requirements, along with a floating roller fixture capable of free rotation. During the test, the fixture secures the rigid material, while the testing machine pulls the flexible material at a constant speed, allowing for the precise measurement of the average peel force required per unit width. The method includes detailed requirements for testing equipment (e.g., a typical jaw separation rate of 100 mm/min) and specimen preparation, aiming to obtain test data with strong comparability and objective reflection of the actual performance of the adhesive.
