Indoor air quality detection is an important index to measure whether a house meets the health requirements of living environment. This paper will introduce the standards of indoor air quality detection, the types of pollutants detected and the relevant civil construction engineering standards.

Detection standard

Indoor air quality testing is based on GB/T 18883-2002 Indoor Air Quality Standard and GB50325-200 1 Code for Environmental Pollutant Control in Civil Construction Engineering.

Formaldehyde standard

There are three standards for formaldehyde in indoor air quality (0. 10, 0.08, 0. 12 mg/m3). The standard of formaldehyde in GB/T 18883 Indoor Air Quality Standard is 0.10 mg/m3; The standard of formaldehyde in GB50325 Code for Indoor Environmental Pollution Control of Civil Building Engineering is ≤0.08mg/m3 for Class I buildings and ≤0. 12mg/m3 for Class II buildings.

Contaminant detection

Indoor air quality detection can detect formaldehyde, triphenyl, ammonia, radon, TVOC and other pollutants in indoor air.

Civil construction engineering standard

Code for Environmental Pollutant Control of Civil Construction Projects (GB50325-200 1) classifies civil construction projects into Class I and Class II. A class of civil construction projects includes residential buildings, hospitals, old-age buildings, kindergartens, school classrooms and other civil construction projects, and a class of civil construction projects includes office buildings, shops, hotels, cultural and entertainment places, bookstores, libraries, exhibition halls, gymnasiums, public transport waiting rooms and so on.
