To test indoor air, do you know which standard to use?

Modern people have an average of 65% of the time at home, 90% of the time in the room. Indoor air directly affects the health of human body. The children's respiratory volume according to the weight of the adult higher than 50%, therefore harm children more vulnerable than adults to indoor air pollution.
With people's attention to the indoor environment is more and more high, choose to do indoor air testing of the family is also more and more. Domestic current indoor air testing standards have two, one is 18883-2002 GB/T "indoor air quality standards", and the other is; GB50325-2010 "civil construction indoor environmental pollution control norms". When we do the test, which standard to choose it? First look at what they have to do with it.
1, GB / t18883-2002 "indoor air quality standards", formulated by the Ministry of health and testing requirements of the doors and windows closed time is 12 hours. It is mainly used for measuring housing is in compliance with the health of the living environment requirements; GB50325-2010 "civil engineering indoor environmental pollution control norms", by the Ministry of construction to develop and testing requirements of the doors and windows closed time is 1 hour is mainly used for civil engineering and interior decoration engineering acceptance of environmental protection detection.
2, the State Environmental Protection Administration and the Ministry of health released the national recommended standard difference GB/T18883, is a guiding standard, healthy living environment scale, construction companies, decoration companies, furniture companies are not binding on and GB50325 is issued by the Ministry of construction mandatory standards, construction, decoration acceptance criteria, of builders and decorators is mandatory requirement is the completion of the project after 1 month after the monitoring. The standard, construction engineering, decoration engineering must perform environmental protection acceptance standards to hand over a completed project, it is strictly prohibited to substandard housing delivery.
3, 18883 index value of the difference between the GB / T standard relates to the indoor environment of physical, chemical, biological, radiological, and a total of 19 indexes, the specification GB50325 only of formaldehyde, benzene, ammonia, TVOC (total volatile organic compounds) and Radon 222 and other five projects to the limit. The limit values of the two standards are in accordance with formaldehyde, benzene, ammonia, TVOC (total volatile organic compounds) and the order of Radon 222 followed by 0.10/0.08, 0.11/0.09, 0.20/0.20, 0.60/0.50, 200/200. GB50325 standard width of some, mainly in order to take care of developers, construction units. GB/T 18883 closer to people's daily living habits, because people in the room indoor total time is generally more than 8 hours. The result of the test is more accurate, it is to protect people's health.
4, according to the test conditions are different, although according to the value of the index, the GB50325 specification than the GB/T 18883 standard requirements but also a little higher, but in fact, the implementation of the test conditions, GB50325 than GB/T 18883 to serious loose. The former provisions should be fully ventilated before testing, and then, only to close the doors and windows for 1 hours to be detected, the latter is required to close the doors and windows for 12 hours after the. After closing the doors and windows of the indoor air and outdoor air can not convection, dilution, the longer the time, the higher the temperature, the higher the concentration of the accumulation of pollutants, so it is often measured out of the GB50325 does not exceed the standard; GB/T 18883. The rest can refer to indoor air testing standards. Different test conditions, often resulting in according to the GB50325 specification for completion acceptance of the delivery of housing, again according to the standard of GB / T 18883 detection and unqualified contradictions, resulting in the various disputes case, the final and is losing homeowners reported is not uncommon.
Through the above comparison, we are not difficult to find that although GB/T 18883 is a recommended standard, but this standard is more stringent than the GB50325, the detection of indicators is also more, so as a person how to choose, the results are obvious.
