1. Formaldehyde. Folem ol nesenel standet, mak bilong 'formaldehyde emisen' bilong 'blockboard' we i yusim 'climate chamber' rot em E1 Liklik o wankain olsem 0.124 mg/m3. Pasin bilong no bihainim ol 'blockboard' we ol i salim long maket wantaim ol 'formaldehyde emission standards' i gat tupela samting: namba wan, 'formaldehyde emission' i winim mak, na dispela i kamapim bikpela hevi long helt bilong ol manmeri; namba tu, sampela prodak, maski 'formaldehyde emission' bilong ol i stap insait long E2 level, ol i no save kamap long E1 level, tasol ol i gat nem olsem E1. Dispela tu i no bihainim lo.
2. Transves Statik Bending Strong. Strong bilong 'transverse static bending' na strong bilong 'bonding' i soim strong bilong ol 'blockboard' prodak long karim ol hevi na sakim 'deformation' aninit long hevi. Ol bikpela as bilong no bihainim lo bilong 'transverse static bending strength' i gat tripela samting: namba wan, ol hevi o bagarap long ol 'raw materials' yet, na dispela i mekim na 'core quality' i no gutpela; namba tu, ol teknik bilong 'splicing' we i no gutpela long taim bilong prodaksen; na namba tri, glu i no stret.
3. Strong bilong Pasin. Pefomens bilong 'bonding' i gat tripela samting insait long en: taim, tempereja, na presa. Hamas na rot bilong yusim 'adhesive' i save mekim tu 'formaldehyde emission index'.
4. Wota i stap insait long en. Wet i stap insait long 'plywood' i soim wet i stap insait long 'plywood'. Sapos wara i antap tumas o i no wankain, prodak inap long senis, bruk, o kamap i no wankain taim yu yusim, na dispela inap long bagarapim wok bilong en.
