Test method for hydraulic setting finishing and/or leveling mortars. Determination of bond strength

This document outlines the standardized procedure for determining the adhesive strength of mortars possessing hydraulic setting properties. It is specifically designed to be applied to both plastering mortars and leveling mortars intended for construction applications. The methodology involves preparing test specimens using the specified materials and subjecting them to controlled conditions to measure the force required to detach the bonded layer. Detailed instructions are provided regarding sample preparation, the conditioning environment, and the equipment necessary for performing the tensile test. Results are expressed in a defined unit of pressure, allowing for consistent comparison across different batches and material formulations. The approach ensures that the adhesion performance of these construction materials can be reliably assessed to verify compliance with technical requirements. By following these established steps, laboratories and manufacturers can evaluate the bonding capability of the mortar to the substrate under defined parameters. This framework supports quality control processes by providing a uniform method for testing the mechanical interaction between the mortar and the base surface.
