Formaldehyde Emission Climatic Test Chamber - TNG1115

The TNG1115 is designed to evaluate the formaldehyde emission levels of textile materials under simulated climatic conditions. The instrument operates by maintaining a controlled environment within its internal chamber, where specimens are exposed to specific temperature and humidity levels. The chamber is insulated with high-density fiberglass wool, 80mm thick, to ensure thermal stability and prevent heat loss. A transparent window made of multi-layered tempered glass allows for visual observation of the specimen without compromising the internal conditions. The internal binding conductive coating is designed to be transparent, heat-insulating, and resistant to steam and frost. The chamber maintains a temperature range of 15°C to 40°C with a fluctuation of ±0.5°C (at loadless state) and a deviation of ≤±2°C (at loadless state). The TNG1115 supports testing in accordance with ASTM D6007-02 and EN V717-1, making it suitable for assessing formaldehyde emissions from a variety of textile materials.

Brief Introduction of Structure

high density fiberglass wool; insulation material thickness: 80mm. The heat inside the internal room may not be conducted to the outside, to keep balanced and stable temperature inside the internal room.

One transparent window is located at a proper position on test chamber door, to obverse the change of

specimen inside the internal room. The window is made by multi layered tempered glass. The internal binding conductive coating is transparent, heat insulation, steam andfrost resistant and other advantages.

The mixing system adopts long axle fan motor, multi-blades wheel, made of stainless steel with good

temperature resistance. The air is circulated forcedly vertically in convection, to keep even and stable temperature inside the internal room.

The door and chamber body are sealed by high elastic double layer seal, with high temperature

resistance. The door inner plate is made by stainless steel. The door adopts non-reaction door handle,easy operation.

The test hole (at the left side of the machine) can be used for connecting power cable or signal cable

(hole diameter and number can be decided by the user).

The cooling system is installed at the bottom. The compressor is “Tecumseh”, imported from France.

The single cooling system can guarantee that the temperature or humidity reaches the setting value within the stipulated time.

Formaldehyde Instrument Introduction At present, due to the differences in the limited value of formaldehyde in various countries, the different test standards, and the differences in the technical capabilities of enterprises, the problems of nonstandard detection often exist. The climate box test method of 1m³ for formaldehyde release is commonly used in foreign countries to detect formaldehyde emissions, it's characteristics is to simulate the indoor climate environment, and the test result is closer to the actual situation. Test Range Formaldehyde Emission Climate Test Chamber, used to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature and relative humidity.
