Standard test conditions are as follows:
1. Temperature: 23 ℃ ~ 28 ℃;
2, relative humidity: (50 ± 5)%;
3, climate box concentration: usually the concentration of organic compounds in the climate box should be below the recommendation value;
Note 1: formaldehyde is 100ug/m³, toluene is 260ug/m³, and toluene is 260ug/m³. Trinopine is 870ug/m³, dichlorobenzene is 240ug/m³, acetic benzene is 3800ug/m³, and the styrene is 220ug/m³.
4. Air replacement rate: 0.5 times /H ±0.05 times/h;
5. Carrier rate: 1m²/m³.Note 2: In the absence of special requirements, you can also surpass the above bearing rate range.
The test report should include the following information:
1. Test laboratory:
Experimental experiment Room name and address;
The name of the person in charge.
2. Sample description:
Product type (and trademark name);
Trial Sample sampling method (for example, random selection); product history (production date, batches, reaching the laboratory date, sealing time, and test sample preparation).
3. Results:
The target VOC, formaldehyde and
other carbon -based compounds, the release concentration or release factor of tvoc.
4. Test conditions:
Test conditions for the climate box (temperature, relative air humidity, air exchange rate, etc.);
Test the area and load rate of the sample;
The samples of the release of VOC, formaldehyde and other carbon -based compounds (adsorption agents, sample volume, sample putting placing sampling process and number of times after climate box);
5. Equipment:Equipment and program information (climate box, sealing material or seal device, background concentration, analysis instrument, etc.).
VOC release quantity test box , also known as VOC release volume test box, VOC test test box, passed the design The temperature, relative humidity, air replacement rate, and air flow speed of the test cabin to simulate the various environmental climate changes in the room, and measure the interior decoration materials, interior decorative materials and people's daily living in this environment. The amount of daily necessities and clothing textiles in this climate release. The internal gas of the experimental cabin is used as the release of the quantity test sample, and then analyzes the harmful organic matter data of the test, and masters the laws of organic pollutants and its concentration over time, so as to determine the release rate and release characteristics of materials and products.
