E1 Certification
This certification scheme concerns the minimum value of the formaldehyde emission in Europe.
The certification for raw or coated wood based panels is granted to productions compliant to the E1 classification as defined by the European Standards in force like UNI EN 13986 involving the technical standards of the sector (or UNI EN 312 when it comes to chipboard, UNI EN 622 for fiberboards, UNI EN 636 for plywood etc.). Moreover, the companies periodically carry out internal control tests for every certified product. The result of this internal control must be sent to the reference technician for the final approval.
E1 class boards (if low emission ones) can be used without causing a balance disorder in the test chamber (according to the UNI RN 717-1 chamber method) when less than 0,1 ppm, as recommended by the World Health Organization for the living spaces.
Stemau S.r.l. periodically carry out internal control tests for the final approval.
