Bituminous sheets. Roof sheeting with layer of glass fibre

This specification outlines the technical requirements for roofing boards manufactured from asphalt with an integrated glass fiber reinforcement layer. The document defines the necessary physical and mechanical properties to ensure durability and performance in various environmental conditions. It specifies test methods used to evaluate tensile strength, water resistance, and dimensional stability of the finished product. Furthermore, the standard establishes guidelines for the composition of the bituminous binder and the distribution of the fibrous mat within the board structure. Detailed procedures for sampling and visual inspection are also included to verify conformity with the established criteria. These requirements are designed to support consistent manufacturing practices and facilitate quality control throughout the production process. The guidelines address key aspects of material behavior under stress and exposure to moisture, ensuring reliability for application in construction projects. Adherence to these parameters helps maintain uniformity in product performance across different production batches and suppliers.
