I-GB / T 5310 luhlobo lwebhobho yebhoyila.

Izinto zayo ezimele i-20g, 20mng, 25mng. Yintsimbi yekhabhoni ephakathi enemanganese encinci.

Ubude bokuhanjiswa kwetyhubhu yebhoyila buhlukaniswe kwiindidi ezimbini: ubungakanani obusisigxina kunye nobukhulu obuphindwe kabini. Ixabiso leyunithi yetyhubhu nganye yasekhaya ibalwa ngokobude obuchaziweyo, kwaye ixabiso letyhubhu nganye libalwa ngokwesisindo sangempela.

Isikali esiphindwe kabini sinokwahlulwa sibe ziindidi ezintathu:

Umlawuli omfutshane: osetyenziselwa ukulungisa umbhobho okhethekileyo wensimbi ongenamthungo kwinkxaso;

Ubukhulu bodonga olulinganayo lombhobho wensimbi ongenamthungo okhethekileyo (ububanzi bangaphandle bungaphantsi kwe-32mm): isetyenziselwa ukwakhiwa komatshini, izixhobo ze-hydraulic ezichaneke kakhulu kunye nokugqitywa kakuhle komphezulu wombhobho wentsimbi ongenamthungo;

Umbhobho wentsimbi ongenamthungo ongekho mgangathweni (idayamitha yangaphandle engaphezulu kwe-32mm okanye i-diameter yangaphakathi engaphantsi kwe-40mm): Isetyenziselwa iindawo ezahlukeneyo zesakhiwo, izixhobo kunye namalungu omatshini.
