Resilient floor coverings - Determination of curling on exposure to moisture

This document establishes a standardized test method for evaluating the curling behavior of resilient floor coverings after exposure to moisture. It outlines the specific procedures required to prepare test specimens, including the necessary conditioning processes and the controlled environment in which samples are subjected to water immersion. The method details how to measure dimensional changes that occur on the surface of the material following the moisture treatment. By following these defined steps, laboratories can obtain consistent and reproducible results regarding the resistance of floor materials to warping caused by wet conditions. The approach ensures that variations in testing do not influence the final assessment of product performance. This procedure is designed to provide a reliable means of comparing different types of resilient flooring in terms of their stability when exposed to dampness. It serves as a technical reference for manufacturers, testing facilities, and regulatory bodies involved in the specification and quality assurance of floor covering products.
