1. Ekirungo kya Formaldehyde. Okusinziira ku mutindo gw’eggwanga, ekkomo ly’okufulumya formaldehyde ku blockboard nga tukozesa enkola ya climate chamber liri E1<=0.124 mg/m3. Obutagoberera bulooka ezitundibwa ku katale n’omutindo gw’omukka gwa formaldehyde okusinga kuzingiramu ebintu bibiri: ekisooka, omukka gwa formaldehyde gusukka omutindo, nga guleeta akabi ak’amaanyi eri obulamu bw’abantu; ekyokubiri, ebintu ebimu, wadde ng’okufulumya kwabyo formaldehyde kuli mu ddaala lya E2, tebituuka ku ddaala lya E1, naye biwandiikibwako nti E1. Kino nakyo kitwalibwa nga ekitali-okugoberera.
2. Amaanyi g’okubeebalama (transverse Static Bending). Amaanyi g’okubeebalama (transverse static bending strength) n’amaanyi g’okukwatagana (bonding strength) biraga obusobozi bw’ebintu ebikolebwa mu bulooka okusitula emigugu n’okuziyiza okukyukakyuka wansi w’okunyigirizibwa. Ensonga enkulu eziviirako obutagoberera mateeka mu maanyi g’okubeebalama agatali gakyukakyuka (transverse static bending strength) za mirundi esatu: ekisooka, obulema oba okuvunda mu bikozesebwa ebisookerwako byennyini, ekivaamu omutindo omubi ogw’omusingi; ekyokubiri, obukodyo bw’okuyunga obutali bwa mutindo mu kiseera ky’okufulumya; n’ekyokusatu, okusiiga mu ngeri etasaana.
3. Amaanyi g’okukwatagana. Omulimu gw’okukwatagana okusinga guzingiramu enkola ssatu: obudde, ebbugumu, ne puleesa. Omuwendo n’engeri y’okukozesaamu ekyesiiga nabyo bikosa omuwendo gw’omukka gwa formaldehyde.
4. Ebirimu Obunnyogovu. Obunnyogovu bulaga obunnyogovu obuli mu plywood. Singa obunnyogovu buba bungi nnyo oba nga tebukwatagana, ekintu ekyo kiyinza okukyukakyuka, okuwuguka oba obutakwatagana nga kikozesebwa, ne kikosa omulimu gwakyo.
