According to the requirements of "GB T 43565-2023 Synthetic Material Surface Basketball Court for Primary and Secondary Schools" and "GB 36246-2018 Synthetic Material Surface Sports Field for Primary and Secondary Schools", the release of harmful substances in school sports fields requires the use of a 60L VOC environmental test chamber to detect the content of harmful substances. Let's take a look.
Test requirements for the content of harmful substances in the surface layer of synthetic materials:
Test Equipment:Huanyi Instrument Synthetic material surface layer 60L environmental test chamber.
Test basis:gb 36246-2018
The test conditions in the cabin of the environmental test chamber are as follows:
air temperature (60 2) ;
Relative humidity of air (5 2)%;
Air exchange rate (1 0.)01)h-1 ;
The air velocity on the surface of the specimen is 01 m/s~0.3 m/s;
The material chamber load ratio is 04 m2/m3。
Pre-test preparation:
The environmental test chamber must be cleaned before the test can be carried out. First, use an alkaline cleaner (pH 7.).5) Clean the interior wall of the cabin, and then scrub the interior wall with deionized or distilled water. After the cleaning is completed, open the hatch and start the fan to air dry the cabin.
After six air changes in the chamber, air sampling is performed to detect the background concentration in the chamber.
Further testing should only be performed if the background concentration of formaldehyde in the cabin does not exceed 6 ug m3, the background concentration of total volatile organic compounds (TVOC) does not exceed 50 ug m3, and the background concentration of other single pollutants does not exceed 5 ug m3.
If you have any questions about the 60L environmental test chamber of the synthetic material surface layer, you can consult".Circumferential instruments"Technicians.
