Are chair backs and seats made by molding wood flour and resin into the desired shape considered particleboard and do they require emission testing?
No, such products would not be considered to be a composite wood product under the ATCM. If products are made to be component parts or finished products, and are not made in the form of flat panel, they are not subject to the regulation. 9. Does the ATCM apply to low density fiberboard (LDF) or high density fiberboard (HDF)? The ATCM applies to LDF, MDF, and HDF. The ANSI standard for MDF, A208.2-2002, is based on performance and is independent of density. 10. The regulation is applicable to hardwood plywood. However, what if the plywood is not hardwood but a softwood like spruce? Is it then exempt? If softwood is used in making HWPW that meets the definition of HWPW (ANSI/HPVA HP-1-2004), then it is subject to the ATCM. The ATCM is intended to apply to products marketed as hardwood plywood with high formaldehyde emissions, which are most commonly made with urea formaldehyde (UF) resins. It is our understanding that “softwood plywood” largely refers to an exterior-grade products made p
