Specification for flexible insulating sleeving. Part 3: Specification requirements for individual types of sleeving. Sheets 403 to 405 : Glass textile sleeving with acrylic based coating.

This document establishes specific technical requirements for various models of sleeving products constructed from glass fabric coated with a polypropylene-based material. It serves as a specialized component within a broader series of international standards dedicated to the performance and safety of insulating sleeving used in electrical applications. The scope of this work focuses on defining precise dimensions, mechanical properties, and electrical characteristics necessary to ensure the reliability of such protective coverings when applied to conductors and assemblies.

Key sections address the material composition, specifically the interaction between the woven glass substrate and the polymeric coating, which provides essential thermal and chemical resistance. Detailed specifications cover tolerance limits, test methods for evaluating flexibility and tensile strength, and criteria for resistance to environmental stressors. These guidelines are intended to facilitate uniformity in manufacturing and quality assurance across different regions, allowing engineers and manufacturers to select appropriate insulation materials based on consistent performance metrics. The content addresses the unique demands of applying these sleeving types in high-temperature or chemically aggressive environments while maintaining electrical integrity throughout their service life.
