1，The steps for formaldehyde emission detection are as follows:Balance pretreatment of formaldehyde detection samples for artificial boards,

2. The sample is placed under the conditions of 23 ± 1 ℃ and relative humidity (50 ± 5)% for 15 ± 2 days. After the pre-treatment is completed, the formal test is carried out, which takes a long time to be conducted in a climate chamber, and the test speed is relatively slow. Each experiment takes more than 20 days, and in order to improve the efficiency of the experiment, Kelute Company has developed a formaldehyde VOC pretreatment chamber to enhance the efficiency of the experiment.

3. The climate chamber avoids the emission of formaldehyde from the samples, which can contaminate each other and affect the test results, greatly improving the accuracy of the test. The multi cabin configuration allows for cyclic testing, greatly improving the efficiency of the experiment. The formaldehyde pretreatment climate chamber is a test equipment specially produced by Kelute Company for the 15 day pretreatment requirements of board samples in GB18580-2017 and GB17657-2013-4.60 standards. This equipment has multiple environmental chambers This model can achieve pre-treatment of 4 sets of standard sample samples without cross contamination. To avoid the problem of mutual interference caused by simultaneous pretreatment of different samples. It can effectively improve the efficiency of sample testing and evaluation by inspection agencies. The test specimens are placed at 23 ± 1 ℃ and relative humidity (50 ± 5)% for (15 ± 2) days, with a distance of at least 25mm between the specimens. The specimens are allowed to circulate freely on all surfaces, and the indoor air exchange rate is at least once per hour at constant temperature and humidity. The mass concentration of formaldehyde in the indoor air cannot exceed 0.10mg/m3.
