He wāhanga matua ngā peera i roto i te ao hanga taputapu ahumahi. Mēnā he pakeke ake te peera, he ātete hoki ki te kakahu, ā, he kaha ake anō hoki te rauemi, kia roa ai te wā e taea ai e te peera te tu atu ki ngā kawenga nui ake, me te mahi tonu mō te wā roa. Nō reira, he mea nui tōna pakari ā-roto ki tōna roanga mahi me tōna kounga.
Mō te whakamātautau pakeke o ngā wāhanga maitai me ngā wāhanga maitai kore-ferrous i muri i te tinei me te whakamahana, me ngā wāhanga maitai kua oti me ngā wāhanga maitai kore-ferrous, ko ngā tikanga whakamātautau matua ko te tikanga whakamātautau pakeke Rockwell, te tikanga whakamātautau pakeke Vickers, te tikanga whakamātautau kaha kume me te tikanga whakamātautau pakeke Leeb, me ētahi atu. I roto i ēnei, ko ngā tikanga tuatahi e rua he mea pūnaha ake, he mea noa ake i roto i te whakamātautau, ā, ko te tikanga Brinell he tikanga ngāwari ake, he mea noa hoki, nā te mea he nui te kōhao whakamātautau, ā, he iti ake te whakamahinga.
E whakamahia whānuitia ana te tikanga whakamātautau pakeke o Rockwell i roto i te umanga peera, ā, ko ōna āhuatanga matua he māmā, he tere hoki.
He māmā noa te whakamahi i te mata pa matihiko whakamātautau pakeke Rockwell. Me uta noa te kaha whakamātautau tuatahi, ā, ka whiwhi aunoa te taputapu whakamātautau pakeke i te uara pakeke.
Ko te tikanga whakamātautau pakeke Vickers e aro ana ki te whakamātautau pakeke o te pou whāriki me te roera porowhita o te whāriki. Me tapahi, me hanga he whakamātautau tauira hei whiwhi i te uara pakeke Vickers.
