I. Te Pakari o Rockwell (HR)
Pāwhiri ki konei mō ētahi atu kōrero mō ā mātou hua.
1. Mātāpono

Mā te whakamahi i te koeko taimana (he koki tihi 120°) he pōro maitai rānei (he whānui 1.59mm, 3.18mm rānei) hei poka, pēhia ki roto i te mata rauemi i raro i te mahi a te kawenga tīmatanga me te kawenga matua. Ka tatauhia te uara pakeke i runga i te hohonutanga o te poka—ka hohonu ake te poka, ka iti ake te uara pakeke.

2. Ngā Āhuatanga

- He tere te whakamātautau me te whakahaere ngāwari, e tika ana mō te whakamātautau puranga.
- Ka taea te whakamātautau i ngā rauemi pakeke waenga ki te pakeke teitei.
- He maha ngā tauine e wātea ana i runga i te pakeke o ngā rauemi:
- HRA: E whakamahi ana i te kawenga 60kg me te kōhao taimana, e tika ana mō ngā rauemi tino mārō pēnei i ngā warowaiha sima.
- HRB: E whakamahi ana i te kawenga 100kg me te kōhao poro maitai, e tika ana mō te maitai ngohengohe, ngā koranu parahi, ngā koranu konumohe, me ētahi atu.
- HRC: E whakamahi ana i te kawenga 150kg me te kōhao taimana, e tika ana mō te maitai kua tineia, ngā koranu pakeke-teitei, me ētahi atu.

3. Ngā Whakamahinga Noa

E whakamahia whānuitia ana mō te whakamātautau tere i te pakeketanga o ngā hua whakarewa pēnei i ngā taputapu tapahi, ngā peera, ngā taputapu me ngā wāhanga rino maka.

II. Te Pakari o Brinell (HBW)

1. Mātāpono

Ka pēhia he pōro koranu mārō o tētahi diameter (10mm te nuinga) ki roto i te mata rauemi i raro i tētahi kawenga kua tohua, ā, ka tatauhia te uara mārō i runga i te diameter kōhao.
Ngā momo noa o te mārō Brinell:

- HBS: He poka poro maitai tēnei e whakamahia ana, he pai mō ngā rauemi he pakeke ≤ 450 HB, pērā i te maitai ngohengohe, te rino maka hina, me ngā konganuku kore-ferro.
- HBW: He kōhao pōro koranu mārō e whakamahia ana, he pai mō ngā rauemi he pakeke ≤ 650 HB, ā, koinei te momo paerewa matua o ēnei rā.

2. Ngā Āhuatanga

- He hua pumau, he pai hoki te whakahokinga.
- He pai mō ngā konganuku ngawari ki te pakeke waenga.
- He nui te kōhao, nō reira kāore e pai mō ngā wāhanga angiangi, ngā wāhanga iti rānei.

3. Ngā Whakamahinga Noa

Te whakamātautau pakeketanga o ngā rauemi mata me ngā wāhanga kua tukatukahia, pērā i te maitai kua whakamahanatia, te rino maka, me ngā konganuku kore-ferrous me ō rātou koranu.

III. Te Mārō o Vickers (HV)

1. Mātāpono

Ka whakamahia he kōhao taimana piramiti tapawhā me te koki tihi 136° hei pēhi ki roto i te mata rauemi i raro i tētahi kawenga kua tohua, ā, ka tatauhia te uara pakeke i runga i te roa hauroki o te kōhao.

2. Ngā Āhuatanga

- Te tino tika: Ka taea te ine tika i te pakeketanga, ahakoa mō ngā wāhi tino iti (hei tauira, ngā rohe moroiti o ngā rauemi).
- Whānuitanga tono: He pai mō te whakamātautau i ngā rauemi puta noa i te whānuitanga o te pakeketanga, mai i ngā konganuku ngohengohe (pēnei i ngā koranu konumohe) ki ngā rauemi tino mārō (pēnei i ngā warowaihā sima).
- He iti noa te kōhao: Mā te kōhao iti e toe ana ki te mata o te rauemi ka karohia ngā wahi mahi kino, he mea tino pai mō ngā wāhanga pakitara angiangi, ngā paninga mata, me te whakamātautau pakeke moroiti.

3. Ngā Whakamahinga Noa

He whānuitia te whakamahinga mō te whakamātautau pakeke o ngā wāhanga tino tika, ngā paninga mata, me ngā pepa angiangi—hei tauira, te ine i te pakeke o ngā paninga anga waea pūkoro hei manatoko i te ātete ki te kakahu. Hei tāpiri, he mea nui i roto i te rangahau pūtaiao mō te tātari pakeke o ngā rohe moroiti, pērā i te whakamātautau pakeke o ngā rohe kōhatu me ngā rohe āhuahanga i roto i ngā rauemi hei ako i ngā āhuatanga moroiti o ngā rauemi.

4. Te Whakataurite i ngā Tikanga Whakamātautau Pakeke e Toru

5.Whakarāpopototanga
He painga anō ō ia tikanga whakamātautau pakeke e toru. Me whiriwhiri whānuitia te tikanga tino tika i runga i ngā āhuatanga o te rauemi, te āhua o te tauira, te whānuitanga o te pakeke me ngā whakaritenga tika kia puta ai ngā hua whakamātautau tino whaitake.
