Kev soj ntsuam zoo ntawm daim ntawv yuav tsum ua tiav peb lub hom phiaj hauv qab no:

Txheeb xyuas qhov ua tiav ntawm daim ntawv. Feem ntau suav nrog: daim ntawv zoo, qhov loj me yog tsim nyog, ntim zoo thiab kev puas tsuaj.

Master daim ntawv yooj yim ntawm daim ntawv. Xws li xim, sib npaug, yooj, tensile kuj, smoothness thiab huv.

Kev kuaj xyuas qhov kwv yees ntawm qhov kev xaiv ntawm cov ntawv luam ntawv tiaj tus (feem pua ntawm cov ntawv nrog cov kab mob pom tseeb).
