Field and Laboratory Emission Cell (FLEC) emissions testing is approved as an emissions testing methodology only for furniture and furnishings that are made up of a uniform material and have flat testing surfaces on which the FLEC emissions testing methodology may be applied. For example, flat surfaced cabinetry that is made up of a uniform material may be tested using this methodology.
