Ukukhutshwa kwe-formaldehyde kufikelela kwi-ENF, ukukhutshwa kwe-formaldehyde elinganiswa ngebhokisi yemozulu ingaphantsi kwe-0.025mg/m³, 0.025mg/m³ ngaphantsi kwe-E0ibakala, kwaye ukuxhathisa kwamanzi kwimveliso kungcono kune-E0ibakala kunye no-E1iimveliso zebakala ezifanayo.
Ifanele ukwenziwa kwefanitshala, intlama yoxinzelelo, ukupeyinta, ukukrola okungenzulu kunye nokukrolwa (ngaphantsi kwe-1/3 ubukhulu bebhodi), isincamathelisi, i-veneer, ukusetyenzwa kwamadyungudyungu kunye nezinye iinjongo.Ineenzuzo zobuso obugudileyo, ulwakhiwo olunengqiqo, i-deformation elula, i-dimensional tolerance encinci, i-uniform density structure kunye nokusebenza okuphezulu.
