Whakamātautau Waipūngao:
Me whakamātauria te paipa rino mā te waipēhi takitahi. Ko te pēhanga whakamātautau mōrahi he 20 MPa. I raro i te pēhanga whakamātautau, kaua e iti iho i te 10 hēkona te wā pumau, ā, kaua te paipa rino e turuturu. Mēnā rānei, ka taea te whakakapi i te whakamātautau waipēhi mā te whakamātautau iahiko rorirori, mā te whakamātautau turuturu rere aukume rānei.
Whakamātautau Kore-Whakangaromanga：
Ko ngā paipa e hiahia ana kia tirotirohia anōtia, me tirotirohia takitahi mā te whakamahi i te ultrasonic. Whai muri i te whiriwhiringa me te whakaae a te rōpū, ā, kua tohua ki roto i te kirimana, ka taea te tāpiri atu i ētahi atu whakamātautau kore-whakangaro.
Whakamātautau Whakapapa
Me whakamātau te whakawhāiti i ngā ngongo he nui ake te whānui o waho i te 22 mm. Kaua e kitea he wehenga, he ira mā, he poke rānei i te roanga o te whakamātautau.
Whakamātautau Pakari:
Mō ngā paipa o ngā momo P91, P92, P122, me P911, Brinell, Vickers, Rockwell rānei, me whakahaere he whakamātautau mārō ki runga i tētahi tauira mai i ia rota.
