BS EN ISO 7619-1: 2010 Roj Hmab, vulcanized lossis thermoplastic Kev txiav txim siab ntawm indentation hardness, Durometer txoj kev (Shore hardness).
Cov txuj ci no ISO 7619-1 qhia meej txog cov txheej txheem rau kev txiav txim siab indentation hardness (Shore hardness) ntawm vulcanized lossis thermoplastic rubber siv durometers nrog cov nplai hauv qab no:
Lub ntsuas rau cov pob zeb txhuam hauv qhov ib txwm-tawv;
⎯ D ntsuas rau cov nplawm pob zeb hauv cov qib siab-siab;
AO nplai rau rubbers hauv thaj chaw qis-rau siab thiab rau cov xaum xoos ntawm tes;
AM nplai rau nyias cov roj hmab xeem ua tej daim nyob hauv qhov ib txwm-hardness ntau.
Cov ntsiab cai thiab xaiv ntawm ISO 7619-1 durometer hom
Cov cuab yeej ntsuas yog qhov tob ntawm kev nkag mus ntawm ib tus neeg ua haujlwm indenter yuam rau hauv cov khoom hauv cov kev cai tswjhwm.
Thaum siv cov durometers, qhov ntsuas yuav tsum tau xaiv raws li hauv qab no:
Rau tus nqi tsawg dua 20 nrog hom D durometer: hom A;
Rau tus nqi tsawg dua 20 nrog hom A durometer: hom AO;
Rau tus nqi tshaj 90 nrog hom Durometer: hom D;
⎯ rau kev kuaj nyias daim (tsawg dua 6 hli tuab): hom AM.
