[154] * derived from figure, CL (core layer), ind. (industrial), MUF (melamine urea-formaldehyde), MUPF (melamine urea phenol-formaldehyde), PF (phenol-formaldehyde), pMDI (polymeric diphenylmethane diisocyanate), PU (polyurethane), and SL (surface layer). In most cases, however, only some of the properties were examined in the various studies. Since IB and MOR were predominantly tested and are included in the standard and industry requirements for the application of panels in the dry interior, IB and MOR values are presented in the tables. In addition, it is highlighted whether they meet the minimum requirements of the European Norm (EN) 622–3: 2004 for fiberboard and EN
