Compliance overview
Scope and applicability
This standard applies to the cleaning of air duct systems in heating, ventilating, and air-conditioning (HVAC) systems that are contaminated by dust particles and biological factors. It is mandatory for cleaning operations in various buildings, including residential, commercial, and healthcare facilities. It does not apply to systems with special requirements for air filtration.
Technical requirements
The standard specifies the requirements for inspecting the cleanliness of ventilation systems, including inspection intervals for different building types. It outlines the conditions that trigger the need for cleaning, such as visible contamination or system performance degradation. It mandates strict engineering environmental controls during the cleaning process. This includes maintaining negative pressure within the ducts and isolating the work area to prevent cross-contamination. Contractors must ensure that the cleaning process does not cause secondary pollution. The use of HEPA-filtered equipment is required in specific scenarios. The standard details mechanical cleaning methods and specific procedures for cleaning various components like air handling units and fiberglass parts. It also addresses the cleaning of biological contaminants, recommending the replacement of contaminated porous materials. GB/T 18883 is referenced for indoor air quality parameters.
Testing methods
The standard provides two main methods for verifying cleaning effectiveness: the Visual Inspection Method and the Weighing Method. The visual method checks if internal surfaces are visibly clean. The weighing method involves wiping a specific area to determine the residual dust amount. The residual dust level must not exceed the specified limit to pass inspection.
FAQs
