Ko ngā āhuatanga matua o te parahi me ngā koranu parahi e whakaata tika ana i te taumata o ō rātou uara pakeke, ā, ko ngā āhuatanga hangarau o tētahi rauemi e whakatau ana i tōna kaha, tōna ātete ki te kakahu, me te ātete ki te hurihanga. Ko ngā tikanga whakamātautau e whai ake nei te tikanga mō te kimi i te pakeke o te parahi me ngā koranu parahi:
1. Tikanga Whakamātautau Pakeke Brinell: E whai ana i ngā whakaritenga whakamātautau pakeke kua tohua i roto i te paerewa o te ao ISO 6506-1:2014 Rauemi Konganuku – Whakamātautau Pakeke Brinell. E pā ana tēnei tikanga whakamātautau ki te parahi parakore, ki te parahi, ki te parahi, ki ngā rauemi parahi ngohengohe rānei; hei tauira, ko te whakaritenga whakamātautau pakeke mō ngā koranu parahi whakarewa ko te whakamātautau Pakeke Brinell (HBW).
2. I runga i te rerekētanga o te pakeke me te matotoru o te parahi, ka taea hoki te whakamahi i ngā tikanga whakamātautau pakeke a Rockwell, a Vickers rānei. Hei tauira, ka taea te whakamātautau i te parahi mā te whakamahi i te tauine HRB (e ai ki te paerewa o te ao ISO 6506-1:2014 Metallic Materials – Rockwell Hardness Test – Part 1: Test Method), ā, ka taea te whakamātautau i ngā pepa parahi mā te whakamahi i te tauine pakeke a HV Vickers. He rerekē ngā paerewa pakeke mō te parahi i runga i ōna hanganga rerekē me ngā āhua maimoatanga wera, ā, me whakahaere te aromatawai i runga i ngā tikanga me ngā paerewa whakamātautau motuhake.
3. Tikanga Whakamātautau Pakeke Webster Kawe: E ai ki te paerewa ā-motu GB/T 32660.1-2016 Rauemi Konganuku – Whakamātautau Pakeke Webster – Wāhanga 1: Tikanga Whakamātautau, e pā ana tēnei tikanga whakamātautau ki te parahi me ōna pepa koranu he angiangi te matotoru o te tauira.
Ko ngā paerewa whakamātautau o runga ake nei te pūtake hangarau mō te whakamātautau i te parahi me ōna koranu. I te whakamātautau i ngā hua, ka tīpakohia e mātou ngā tikanga whakamātautau rerekē i runga i te momo rauemi me te whakamahinga.
