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 te taputapu kotahi. Ka whakamatautauria te taputapu whakamātautau pakeke Universal i runga i ngā mātāpono o Rockwell, Brinell, me Vickers, kaua ki te whakamahi i te whanaungatanga tahuritanga o te pūnaha pakeke hei whakaputa i ngā uara pakeke maha.
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 whakamātautau i ngā pokepokea, te ine i te pakeketanga o ngā wāhanga kua tineia, kua tineia me ngā wāhanga kua whakamahanatia.
He pai te tauine pakeke HV Vickers mō: te ine i te pakeketanga o ngā tauira me ngā wāhanga he iti ngā horahanga me ngā uara pakeketanga teitei, te pakeketanga o ngā paparanga kua uruhia, ngā paninga rānei i muri i ngā maimoatanga mata rerekē, me te pakeketanga o ngā rauemi angiangi.
Ko te kupu whakataki tēnei mō te raupapa hou o ngā taputapu whakamātautau pakeke o te Ao: me te taputapu whakamātautau pakeke o te mata pa
He rerekē tēnei i te taputapu whakamātautau pakeke Universal tuku iho, ka whakamahia e te taputapu whakamātautau pakeke Universal o te whakatupuranga hou te hangarau pūoko kaha me te pūnaha urupare kaha porowhita-katia hei whakakapi i te tauira uta taumaha, kia māmā ake ai te ine, kia pumau ake ai hoki te uara ine.
