Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and marking for flexible ventilation ducting made from rubber- or plastics-coated fabrics. It is primarily applied in underground mining, tunneling, and construction ventilation systems to ensure the ducting's air-tightness, flame resistance, and durability under harsh conditions. The standard provides a basis for quality control and procurement of these ducts in industrial safety and ventilation engineering contexts.
