EN717-1 EN717-1: 2004 wooden board - formaldehyde release test set - Part 1: Determination of formaldehyde release by the chamber. EN717-1: 2004 Wood-based panels-determination of formalehyde release-Part 1: Formaldehyde emission by the chamber method Formaldehyde is a colorless, flammable gas with a pungent odor evident. It is an important chemical that is widely used in all types of building materials and household goods production. At the same time, it is also the combustion and certain other natural byproduct of the change. The main source is the use of formaldehyde-containing urea-formaldehyde (UF) adhesive resins produced compressed wood products. Compressed wood products for indoor use include: particleboard (for wool flooring and shelving, cabinetry and furniture in general), hardwood plywood (for wall decoration, cabinets and furniture), and medium density fiberboard (for the front drawer plates, cabinets and furniture top). Formaldehyde by the US Environmental Protection Agency (USEPA) classified as possibly carcinogenic to humans substances. IARC (IARC) also believes there is "sufficient evidence" shows that occupational exposure to formaldehyde can cause people to risk of nasopharyngeal cancer.
