Formaldehyde Emission Test Chamber Standards:
ASTM D6007—14《Standard Test Method for Determining Formaldehyde Concentrations in Air from Wood Products Using a Small-Scale Chamber》
EN 717-1 Wood-Based Panels Determination of Formaldehyde Release-Part 1：Formaldehyde
Working principle：
Put sample of 1 square meter area into the temperature chamber which controlled control in a certain value of temperature, relative humidity, air velocity. The formaldehyde released from samples, mixed with the air in the cabinet, regular extraction in the air, and the air will be drawn through the absorption bottle is filled with distilled water, all the formaldehyde in air dissolve in the water; Measure the amount of formaldehyde in the absorption solution and extraction of air volume, and show it by micrograms per cubic meter (mg/m after), calculate the amount of formaldehyde in per cubic meter of air. Sampling is cyclical, until the test the formaldehyde concentration in the oven to reach equilibrium.
After-service:
If you face any problems in future during testing process we promise we will give you a reply within 48 hours and solution provide within 3 working days. We can offer operation video and English operation muanual. We can provide video-con.
