1 General provisions
1.0.1 This code is formulated with a view to preventing and controlling indoor environmental pollution caused by building materials and decoration materials in civil building engineering, protecting public health, safeguarding public interests, and achieving advanced technology, economy and rationality, in combination with the actual situation of Guangdong Province.
1.0.2 This code is applicable to indoor environmental pollution control for new construction, extension and renovation of civil buildings, and not applicable to indoor environmental pollution control for industrial building engineering, warehouse building engineering or structures, and rooms with special purification or sanitation requirements.
Notes:
1 Indoor environmental pollution hereof refers to indoor environmental pollution caused by building materials and decoration materials. After the civil building engineering is delivered for use, indoor environmental pollution caused by non-building decoration materials is not within the control range of this code.
2 Indoor air pollutant content detection in industrial buildings or other buildings may refer to this code.
1.0.3 Indoor environmental pollutants controlled in this code are radon (Rn-222), formaldehyde, ammonia, benzene and total volatile organic compounds (TVOC).
1.0.4 Civil building engineering are divided into the following two categories according to different requirements for controlling indoor environmental pollution:
1 Class I civil building engineering: residential buildings, hospitals, buildings for the aged, kindergartens, school classrooms and other civil building engineering;
2 Class II civil building engineering: office buildings, shops, hotels, cultural and entertainment places, bookstores, libraries, exhibition halls, gymnasiums, waiting rooms for public transportation, restaurants, barbershops and other civil building engineering as well as office places in industrial buildings.
1.0.5 The main building materials and decoration materials used in civil building engineering must meet the requirements hereof.
1.0.6 In addition to the requirements specified hereof, the indoor environmental pollution control of civil building engineering shall also meet the relevant national and professional current standards.
