Things to Note When Testing Decoration Materials in Formaldehyde and VOC Test Chambers

After purchasing the formaldehyde Voc Test Chamber, some buyers used it improperly or did not pay attention to the proportion of the test materials, resulting in test results that did not meet the requirements. The following will show you what you should pay attention to when using the formaldehyde VOC test chamber to test decoration materials.

The formaldehyde VOC emission Environmental Chamber produced by Huanyi Company is used as the detection instrument, as shown below:

I. Equipment name: Formaldehyde emission detection Climate Chamber, also known as VOC emission environmental test chamber or formaldehyde and VOC emission test chamber
II. Standards met by the testing equipment: GB 50325-2020 "Standard for Indoor Environmental Pollution Control of Civil Construction Engineering"
III. Operating conditions of formaldehyde and VOC test chamber:
1. Environmental test chamber size volume: 0.05m3---40m3
2. The temperature should be (23±0.5)℃;
3. The relative humidity should be (50±3)%;
4. The air exchange rate should be (1±0.05) times/h;
5. The air flow rate near the surface of the sample to be tested should be 0.1m/s~0.3m/s;
6. The ratio of the surface area of ​​artificial wood boards and their products, bonded wood structural materials, wall cloths, curtains, soft-pack samples and the volume of the environmental test chamber should be 1: 1. The ratio of the area of ​​carpet and carpet pad samples to the volume of the environmental test chamber should be 0.4:1;
7. Before the formaldehyde and VOC release of material samples is measured, the formaldehyde concentration in the clean air in the environmental test chamber should not be greater than 0.006mg/m2, and the VOC concentration should not be greater than 0.01mg/m2.
IV. Scope of application:
Formaldehyde and VOC test chambers are generally used to test artificial wood boards and their products, bonded wood structural materials, wall cloths, curtains, integrated home furnishings, curtains, latex paints, etc.
V. Use precautions
1. The materials tested should not exceed or be less than the corresponding test ratio;
2. The operating temperature of the equipment should reach the relevant temperature. If it is lower than the specified test temperature, formaldehyde and VOC will not be fully released;
3. The materials tested should not include other gases that release formaldehyde and VOC;
4. Other irrelevant materials should not be placed in the formaldehyde and VOC test chambers;
The above are the issues that should be paid attention to when using formaldehyde VOC test chambers to test decoration materials.
