Rangatira Kounga Mata
1.Ko nga hapa me nga kohao kia kaua e neke atu i te rua nga waahanga i runga i te mata hiko graphite, a ko nga hapa me te rahi o nga kohao kaore e whakaaetia kia nui atu i nga raraunga i te ripanga i raro nei.
2.Kare he kapiti whakawhiti i runga i te mata hiko.Mo te kapiti roa, ko tona roa kia kaua e neke ake i te 5% o te porowhita hiko kauwhata, me noho tona whanui i roto i te awhe 0.3-1.0mm.Ko nga raraunga kapiti roa kei raro i nga raraunga 0.3mm kia iti
3.Ko te whanui o te waahi taratara(pango) i runga i te mata hiko kauwhata kia kaua e iti iho i te 1/10 o te porowhita hiko kauwhata, me te roa o te waahi taratara(pango) i runga i te 1/3 o te roanga hiko kauwhata. e kore e whakaaetia.
