ISO, GB, JIS cov qauv:
Qhov ntsuas yog muab sib piv ntawm qib ntawm tus qauv ntawm xiav woolen daim ntaub nrog sib phim raug raws li qhov ntsuas. Daim ntawv lo lo ntxhuav xiav tau muab faib ua qib 1 ~ 8. Hauv txoj ntsiab cai, cov qauv kuaj yuav tsum tau tiv tshav tiv tshav ntuj ua ke nrog cov qib ntsuas ntawm daim paib xiav. Xws li theem ntawm 4, qhov tshwm sim yuav tsum yog> theem 4,=theem 4,< theem="">
AATCC txuj: kev muab qhab nia tseem tau ua los ntawm kev piv ntawm daim npav xim txho, thiab cov txiaj ntsig tau qhia tias tib xim xim nrawm dua li cov qauv AATCC.
