Ko te taputapu whakamātautau pakeke Universal he taputapu whakamātautau whānui e hangai ana ki ngā paerewa ISO me ASTM, e āhei ai ngā kaiwhakamahi ki te whakahaere i ngā whakamātautau pakeke Rockwell, Vickers me Brinell i runga i ngā taputapu kotahi. Ka whakamatautauria te taputapu whakamātautau pakeke universal i runga i ngā mātāpono Rockwell, Brinell, me Vickers, kaua ki te whakamahi i te whanaungatanga tahuritanga o te pūnaha pakeke hei whakaputa i ngā uara pakeke maha.
E toru ngā pauna pakeke e tika ana mō te ine i ngā mea mahi
He pai te tauine pakeke HB Brinell mō te ine i te pakeke o te rino maka, ngā koranu kore-ferrous, me ngā momo maitai kua whakamahanatia me ngā maitai kua whakamahanatia. Kāore e pai mō te ine i ngā tauira, i ngā mea mahi rānei he pakeke rawa, he iti rawa, he angiangi rawa, ā, kāore e whakaaetia kia nui ngā kōhao i runga i te mata.
He pai te tauine pakeke HR Rockwell mō: te ine i te pakeke o ngā pokepokea whakamātautau, te tinei, te whakamātao me te whakamahana i ngā wāhanga kua tukatukahia ki te wera.
He pai te tauine pakeke HV Vickers mō te ine i te pakeke o ngā tauira me ngā wāhanga he iti ngā horahanga me ngā uara pakeke teitei, te pakeke o ngā paparanga kua uruhia, ngā paninga rānei i muri i ngā maimoatanga mata rerekē, me te pakeke o ngā rauemi angiangi.
He whānuitanga hou o ngā taputapu whakamātautau mārō whānui
He rerekē i te taputapu whakamātautau pakeke whānui tuku iho: ka whakamahia e te taputapu whakamātautau pakeke whānui o te whakatupuranga hou te hangarau pūoko kaha me te pūnaha urupare kaha porowhita-katia hei whakakapi i te tauira whakahaere uta-taumaha, kia māmā ake ai te ine, kia pumau ake ai te uara ine.
Te tohu aunoatanga kōwhiringa: momo hiki aunoa o te pane mīhini, momo whakaatu matihiko mata pa, momo ine rorohiko
