BS EN 13062:2003 PDF Download

BS EN 13062:2003 is a test method standard that focuses on the determination of thixotropy in products and systems used for the protection of reinforcement in concrete structures. Thixotropy refers to the property of certain materials that exhibit a temporary reduction in viscosity when subjected to shear stress, and regain their original high viscosity when left undisturbed. The purpose of this standard is to provide a consistent method for assessing the thixotropic behavior of products and systems, ensuring their effectiveness in protecting reinforcement in concrete structures.

The standard outlines the specific procedures and equipment required to carry out the thixotropy test. These include the preparation of a sample of the product or system, measuring its initial and final viscosity, and subjecting the sample to controlled shearing using a specific apparatus. The test measures the change in viscosity of the sample before and after shearing, determining its thixotropic behavior.

By establishing a standardized method for evaluating thixotropy, BS EN 13062:2003 enables manufacturers and users of products and systems for the protection of reinforcement to assess their performance consistently. This helps ensure that the products and systems can effectively protect and repair concrete structures, particularly regarding the reinforcement, which is essential for their structural integrity and longevity.
