Measuring methods and requirements for waterproofing membrane Coating thickness measurement are specified in the GMW15726 standard. The standard is mainly used to determine the thickness of waterproofing membrane surface coatings to ensure that they have the required waterproof performance and durability. The standard details the applicable conditions of different coating measurement technologies, including the instruments used, the selection of Measuring location and the operation steps to ensure the accuracy and repeatability of the measurement. The implementation of this standard aims to improve the accuracy of waterproofing membrane coating mass control and ensure the long-term effectiveness and Stability of Water proofer in the application.
