Fixed firefighting systems - Hose systems - Part 2: Hose systems with lay-flat hose

This document addresses the technical requirements for components of stationary fire protection systems, specifically focusing on the second section dedicated to flat hose assemblies. It establishes the specifications for the design, construction, testing, and marking of hoses arranged in a flat configuration, ensuring they are suitable for their intended safety applications. The scope covers material properties, dimensional tolerances, pressure ratings, and performance criteria necessary to maintain reliability during emergency operations. Detailed provisions outline the manufacturing processes and quality control measures required to produce these systems effectively. Comprehensive testing protocols are included to verify the integrity and functionality of the hose assemblies under various conditions. The guidelines also specify labeling requirements to ensure proper identification and usage instructions are clearly communicated to operators and maintenance personnel. Adherence to these specifications supports the consistent performance of fire suppression infrastructure in both commercial and industrial settings. The text serves as a technical reference for manufacturers and inspectors involved in the production and validation of fire protection equipment. It aims to harmonize product standards across regions to facilitate trade and ensure a uniform level of safety.
