When the synthetic materials in the sports field are tested for volatile organic compounds, the samples need to be sampled and analyzed.
Sampling and analysis of synthetic material samples in sports fields:
Test Equipment:Huanyi Instrument Synthetic material surface layer 60L environmental test chamber.
According to the standard:gb 36246-2018
Sampling Analysis:
1.The specimen was equilibrated in the environmental test chamber for (24 ±1) h and then subjected to cabin air sampling analysis.
2.The sample flow rate should not be greater than 80% of the air flow supplied by the environmental chamber.
Specific requirements:
a.When the adsorption tube method is used to collect pollutants in the air in the environmental cabin, it should be ensured that the adsorption tube is directly connected to the air outlet of the environmental cabin, and there should be no connecting pipe between the two, so as to avoid the adsorption and condensation of the analyte in the connecting tube When the absorption bottle method is used to collect formaldehyde, the length of the connecting pipe between the absorption bottle and the outlet of the environmental cabin should be as short as possible, and the transmission pipe should be made of inert materials such as PTFE or silica gel, and the longest should not exceed 30 cm.
Since this method is a high-temperature sampling under 60 conditions, the laboratory should pay attention to the adsorption capacity and adsorption capacity of the adsorption tube used, and pay attention to the possibility of low boiling point pollutants penetrating in the adsorption tube, and if necessary, the method of series adsorption tube should be used for sampling.
Total. b.Except for benzene, toluene, p-xylene, o-xylene, styrene, ethylbenzene, butyl acetate, and undecane, the other unknown peaks of volatile organic compounds (TVOCs) were calculated based on the response factors of toluene.
c.The arbitration shall be conducted in accordance with the methods set forth in ISO 16000-3.
If you have any questions about the testing of synthetic material samples in the sports field, you can consult".Circumferential instruments"Relevant technicians.
