HD-F801-1 VOC Test Chamber EQUIPMENT DETAILS
It is used to test VOC (volatile organic compound) emission of various wood-based panel, composite wood flooring, carpet, carpet padding, and other interior decoration materials, also other building materials under constant temperature humidity.
Put sample into 1000L square test chamber, under specify temperature, humidity, air velocity. The VOC and formaldehyde will released from samples and mixed with the air in the chamber, 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/m³).
ISO 16000-9 <Part9: Determination of the emission of volatile organic compounds from building products and compounds from building products and furnishing—Emission test chamber method>
EN 16516 <Construction products: Assessments of release of dangerous substances – Determination of emissions into indoor air>
