Part 2 of this standard specifies the test method for tile Adhesives, which is designed to evaluate the performance of Adhesives under different application conditions. The standard includes a variety of Adhesives performance test items, such as initial bond strength, tensile strength, peel strength, water resistance and heat resistance, etc., to ensure that it meets the requirements of tile laying and fixing. Through a series of standardized experimental procedures, the actual application performance of Adhesives is tested to help manufacturers, suppliers and users choose the right product and ensure mass construction.
