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

This technical specification establishes comprehensive requirements and test methods for hose systems within fixed fire fighting installations. The document specifically addresses configurations utilizing flat hose arrangements, which are designed to offer enhanced storage efficiency and rapid deployment capabilities. Detailed provisions outline the necessary mechanical performance criteria, including pressure resistance, flexibility, and durability under operational stress. Material specifications ensure that the components maintain structural integrity when subjected to high water flow and potential abrasion during emergency scenarios. The standard defines testing protocols to verify that hose assemblies meet consistent safety benchmarks for reliability and service life. Furthermore, it provides guidance on marking and identification to facilitate proper installation and maintenance procedures by authorized personnel. Compliance with these technical parameters is essential for ensuring the effectiveness of fire suppression systems in various building environments. The document serves as a reference for manufacturers, installers, and inspectors involved in the production and validation of such fire safety equipment.
