Whakaritenga Whakamatau
Whakamātautau papatahi
Ko nga ngongo rino he nui ake te diameter o waho i te 22 mm, tae atu ki te 400 mm, me te matotoru o te pakitara nui ake i te 10 mm me uru ki te whakamatautau papatahi. I muri i nga tauira ka papatahi
Te whakamatautau piko
Ko nga ngongo maitai me te diameter o waho kaua e nui ake i te 22 mm me uru ki te whakamatautau piko. Ko te koki piko he 90o. Ko te radius piko he 6 wa te diameter o waho o te ngongo maitai.I muri i te piko o te tauira, kaore he kapiti, he kapiti ranei e whakaaetia kia puta ki runga i te tauira.
Te whakamātautau macroscopic
Mo nga ngongo rino i mahia tikatia e nga pire me te rino rino e mau tonu ana, me kii te roopu tuku karekau he wahi ma, he poke, he mirumiru hau i raro i te mata, he papa angaanga, he paparanga ranei i runga i te kopa tonotono î waikawa-waahanga o te pire, ngongo maitai.
Te tirotiro kino kore
E ai ki te tono a te roopu tono, ka whiriwhiria i waenga i nga roopu tuku me nga roopu tono me te tohu i roto i te whakaaetanga, ka taea te mahi takitahi te rapu koha ultrasonic mo nga ngongo maitai. Ko te koha a-ringa roa o te ngongo tauira tohutoro me tutuki nga whakaritenga mo te tohu whakaaetanga i muri i te tirotiro C8 kua tohua ki te GB/T 5777-1996.
