content briefly: GB - 'Civil engineering indoor environment pollution control standards' ( Hereinafter referred to as the standard) Than the nikkei stock of housing and urban-rural development of the People's Republic of China approved the release, since (date) (month) (year), which will greatly promote the development of ecological diatom mud wall material, standard industry standard, push forward the diatom ooze industry. GB - 'Civil engineering indoor environment pollution control standards' ( Hereinafter referred to as the standard) Than the nikkei stock of housing and urban-rural development of the People's Republic of China approved the release, since (date) (month) (year), which will greatly promote the development of ecological diatom mud wall material, standard industry standard, push forward the diatom ooze industry.

the revision of this standard content is very much, because the sago is specializes in integrated custom metope, the small card listed here is mainly the part of indoor pollution control and monitoring in the revision content, other amendments please read standard in full.
　　
　　（ ） Increased in indoor air pollutant

GB - （ Edition) There is a (of indoor air pollutants in Radon, formaldehyde, benzene, ammonia and TVOC) This standard in GB - （ Edition) Increased the toluene and xylene, on the basis of the aggregate.
　　
　　（ ） Strict limit in indoor air pollutants concentration

(1) this standard limit than GB - most of the pollutants concentration （ Edition) Strict and part of the pollutant concentration limit even than the 'standard of indoor air quality' GB/T - More strictly.

2. Due to this standard and GB/T - Standard of indoor air pollutant sampling requirements ( Such as sampling Windows and doors before closing time) Is different, so it cannot be directly compared.

　　（ ） More strictly control the decoration pollution requirements

1) for the kindergarten, school classrooms, dormitories and other decoration puts forward stricter requirement for pollution control.

2. This standard. 。 Article, kindergarten, school classrooms, dormitories, indoor decoration acceptance, the elderly care for housing in indoor air radon, formaldehyde, ammonia, benzene, toluene, xylene, TVOC sampling amount shall not be less than % of the total number of room, and shall not be less than. When the room is not greater than the total should be tested.
　　
　　（ ） On the indoor pollutant concentration detection points to adjust the

on the indoor pollutant concentration detection points set have been adjusted. This standard adjustment in the area of more than square meters room were used to detect points set.
　
　　（ ） Has been clear about the test method of radon concentration in indoor air

1 GB - （ Edition) Only the measurement results of radon concentration detection method and uncertainty, request the minimum detectable limit and there is no clear which detection method to choose.

2. This standard has been clear about the civil building in radon concentration in indoor air testing appropriate USES pumped electrostatic collecting energy spectrum analysis, pumped scintillation chamber, pump pulse ionization chamber method, active carbon absorption box - Low background multichannel & gamma; The spectrometer method.
　　
　　（ ） Indoor air pollutant sampling measurement requirements

increase the benzene and volatile organic compounds ( TVOC) The T - C composite absorption tube ( ，- The porous polymer - phenyl diphenyl ether The graphitized carbon black - X compound adsorption tubes) Sampling test method to further improve and refine the indoor air pollutant sampling measurement requirements.

the new 'civil engineering indoor environment pollution control standard', to vigorously promote the development of diatom ooze:

anything is not absolute, revision of the implementation of this standard is in order to improve the indoor and outdoor pollution control of civil engineering, thus to protect people from the decoration pollution, access to better and more healthy home life.

but, to completely eliminate decoration pollution is not realistic, but also do not want excessive decoration, for example, the metope of indoor environmental protection such as diatom ooze are functional materials, diatom mud can not only absorb the decomposition of the indoor air formaldehyde, ammonia, benzene, toluene, TVOC, etc. , also has certain ornamental, beautiful and healthy, very suitable for a family to decorate children room, old person room and bedroom.
