When our people are living in the room, not only are things not arranged neatly, but also we will face the air that we have to breathe every day. Below is the indoor air detection and control that Xiaobian wants to tell you. The first is the choice of testing standards 1 "Code for indoor environmental pollution control of civil construction projects" GB50325-2001 (2006 version) is a national mandatory standard and must be enforced; "Indoor Air Quality Standard" GB/T18883-2002 is the national recommended standard, is not mandatory Laws and regulations are mandatory only if the parties to the contract agree to meet the standards in the agreement. 2 After the decoration is completed, the consumer shall carry out the test according to the “Code for Indoor Environmental Pollution Control of Civil Building Engineering†GB50325-2001 (2006 version); after the furniture is in place or after a period of stay, the indoor air quality standard shall be adopted GB/T18883 -2002 for indoor air quality testing. Second detection time 1 "Code for Indoor Environmental Pollution Control of Civil Buildings" stipulates that civil construction projects shall be carried out at least seven days after the completion of the renovation works and before the use of the project. 2 It is recommended that the personal decoration family should be tested one month after the completion of the renovation project, and all the furniture should be fully in place after one week. During this period, adequate ventilation should be ensured to facilitate the emission of harmful substances, so that the test results are closer to the actual use. The situation. Third closed time control 1 "Code for Indoor Environmental Pollution Control of Civil Buildings": For civil construction projects using natural ventilation, the sampling shall be carried out 1 hour after the closing of the external doors and windows; â–² When a dispute arises, the closing time of the external doors and windows shall be 1h (hours). . 2 For the decoration family who are preparing to stay or have already stayed, according to the "Indoor Air Quality Standard" GB/T18883-2002, the door and window closing time of the sampling is 12 hours (ie: the closing time of people sleeping at night is 12 hours) The above will not exceed 20 hours), so the detection result of the door and window closing for 12 to 20 hours during air sampling will be closer to reality. 3Because the daily traffic on the road needs time, etc., we will usually arrive at the test location you need around 9 am on the test day, so when you have an appointment with us, you should be on the day before the test date. From 17:00 to 22:30 in the evening, close the doors and windows of the space you want to detect or calculate the closed room according to the agreed inspection time. After we have finished sampling, we can open the door and open the window. Determination of the fourth sampling point 1 "Code for indoor environmental pollution control of civil construction projects" GB50325-2001 (2006 version) stipulates: when the room use area is <50 square meters, the number of detection points: 1; when the room use area is ≥ 50 squares and <100 square, the number of detection points: 2 When the room usage area is ≥100 square meters and <500 square meters, the number of detection points: not less than three. 2 According to the actual situation, the room area of ​​a typical individual residence is <50 square meters, so only one detection point is required for one room; when the living room area is <50 square meters, only one detection point is needed; if the living room area is >50 square meters It should be determined according to the actual situation. 3 â— Specific to 1 set of housing, general kitchen, bathroom does not have a detection point; â— General two-bedroom and one-bedroom housing set up 3 inspection points, that is, two inspection rooms in two rooms and living room; â— three-bedroom and one-bedroom housing There are 4 inspection points, that is, one inspection point for each of the three rooms and the living room; â— Other housing types such as three bedrooms, two halls, and the middle building should be determined according to the actual situation. Indoor air detection and control It is a process of analyzing and testing the environmental pollution caused by indoor decoration and furniture addition, and issuing a legally valid test report by the National Authority (CMA). According to the test results, we can judge the indoors. Concentration of pollutants and targeted prevention and control measures. Because the types of indoor air pollutants are complex and the concentration is sometimes low, the impact on human health is long-term and chronic. Dry eyes, lethargy, memory loss, etc. may occur in the early stage; long-term exposure may cause sore throat, acute or chronic pharyngitis, etc. Long-term exposure to a contaminated environment will lead to the development of lung and multiple organ diseases. Now everyone understands about our indoor air detection and control. Xiaobian believes that in the future, each of our families will smoothly complete their own house and live happily every day. This knowledge is found in Xiaobian's home network of decoration, and everyone will pay attention to it in the future. More related wonderful reading: How to do indoor decoration air detection?
