I-GB/T 5310 luhlobo lwetyhubhu yebhoyila.

Izinto ezimele yona yi-20g, 20mng, 25mng. Yintsimbi yekhabhoni ephakathi ene-manganese encinci.

Ubude bokuhanjiswa kwetyhubhu yebhoyila bahlulwe baba ziintlobo ezimbini: ubungakanani obuzinzileyo kunye nobukhulu obuphindwe kabini. Ixabiso leyunithi yetyhubhu nganye yasekhaya libalwa ngokobude obuchaziweyo, kwaye ixabiso letyhubhu nganye libalwa ngokobunzima bokwenyani.

Isikali esiphindwe kabini singahlulwa sibe ziintlobo ezintathu:

Irula emfutshane: isetyenziselwa ukulungisa umbhobho wentsimbi okhethekileyo ongenamthungo kwinkxaso;

Ubukhulu bodonga obulinganayo bombhobho wentsimbi engenamthungo onemilo ekhethekileyo (ububanzi bangaphandle bungaphantsi kwama-32mm): osetyenziselwa ulwakhiwo loomatshini, izixhobo ze-hydraulic ezichanekileyo kakhulu kunye nokugqitywa kakuhle komphezulu wombhobho wentsimbi engenamthungo ochanekileyo;

Umbhobho wentsimbi ongeyomthungo oqhelekileyo (ububanzi bangaphandle obungaphezulu kwama-32mm okanye ububanzi bangaphakathi obungaphantsi kwama-40mm): Usetyenziselwa iindawo ezahlukeneyo zesakhiwo, izixhobo kunye neendawo zoomatshini.
