Scope

Scope: This standard applies to the design, construction, and quality acceptance of exhaust duct systems for residential kitchens and bathrooms with a height of less than 100m in newly built, expanded, or renovated buildings. Main technical content: The main content of this standard includes 7 chapters and 10 appendices: 1. General provisions, 2. Terminology, 3. Basic requirements, 4. Materials and components, 5. Design, 6. Construction, 7. Performance testing and quality acceptance. Appendices A-C are normative appendices. This standard specifies the essential functions and components of exhaust duct systems, the technical requirements of each component, the key control points in the design and construction process, and the performance testing and quality acceptance of finished products. It emphasizes system coordination and functional testing. 2.0.1 Exhaust duct systems for residential kitchens and bathrooms consist of exhaust ducts, fire-resistant and smoke-proof components, roof hoods, and compatible range hoods or exhaust fans. They are used to discharge fumes from cooking activities in kitchens and dirty air from bathrooms outdoors, while also providing anti-backflow and fire-resistant functions. In this standard, they are referred to as residential exhaust duct systems. 3.0.1 Residential exhaust duct systems should be used as a complete system, with all components matched and supplied by the system supplier, not mixed with other components. 3.0.2 The exhaust duct system should meet the requirements of smooth exhaust, fire resistance, and prevention of smoke and odor cross-contamination and backflow. 3.0.7 The exhaust duct system should have structural measures for fire resistance and prevention of smoke and odor cross-contamination. 3.0.8 After the installation of the exhaust duct system is completed, on-site dynamic ventilation performance testing should be conducted.
