A cikin samarwa da amfani da bututun ƙarfe, ƙaddarar taurin su yana da mahimmanci. Za a iya auna taurin bututun ƙarfe ta wasu na'urori masu auna taurin ƙarfi kamar Rockwell, Brinell, da Vickers wanda Kamfanin Laizhou Laihua Testing Instrument Factory ya kera, waɗanda za a iya keɓance su kamar yadda ake buƙata. Babban hanyoyin aunawa sun haɗa da:
1. Hanyar gwajin taurin Rockwell
Gwajin taurin Rockwell a halin yanzu shine hanyar da aka fi amfani da ita, wanda HRC ta kasance ta biyu kawai ga Brinell hardness HB a daidaitaccen bututun ƙarfe. Yana auna zurfin shigarwa kuma ana iya amfani dashi don auna kayan ƙarfe daga mai laushi mai laushi zuwa matuƙar wuya. Ya fi sauƙi fiye da hanyar gwajin Brinell.
2. Hanyar gwajin taurin Brinell
