Kaore pea e pa ana nga paatata matotoru o te pakitara ki nga pakitara 0.199 inihi (5.05 mm) me te iti ake; korero ki te kaiwhakanao mo nga whakaahuru pakitara mo enei rahi ngongo.

he ahua nui ake, katahi ka tohua nga ngongo kua mahi makariri ki te diameter o roto me te matotoru pakitara, te diameter o waho me te diameter o roto.

Ngongo Miihini Kua Hurihia—Ko te rereke o te diameter o waho me te matotoru o te pakitara kaua e neke atu i te pai o te Ripanga. Ka hipokina e te ripanga nga whakamaaramatanga e pa ana ki te diameter o waho me te matotoru pakitara ka pa ki te rahi kua tohua.

Nga Puawai Miihini Whenua—Ko te rereke o te diameter o waho kaua e neke atu i nga whakaaheitanga o te Ripanga. Ko te tikanga ka mahia tenei hua mai i te ngongo mahi makariri.

Te Roa—Ko nga ngongo miihini ka mahia i roto i te mira te roa, 5 ft (1.5 m) neke atu. Ko te roa o te tapahi kua oti te whakarite ina tohua e te kaihoko. Kei te Ripanga te roa o nga whakaatete.

Torotika—Ko nga herenga tika mo nga ngongo porowhita kore e neke ake i nga moni kua whakaatuhia ki te Ripanga.

Whakaritenga Whakamatau

1.Whakamātautau Mārō
I te wa e hiahiatia ana nga rohe pakeke, me korero ki te kaihanga. Kua whakarārangihia nga pakeke angamaheni ki te Ripanga .I te wa i tohua, ka mahia te whakamatautau pakeke ki te 1% o nga ngongo.

2.Tension Tests
I te wa e hiahiatia ana nga ahuatanga tensile, me korero ki te kaihanga. Kua whakarārangitia ngā āhuatanga mārō mō ētahi o ngā kōeke me ngā āhuatanga waiariki ki te ripanga.

3.Ko Nga Whakamatau Kore Whakamate
He maha nga momo whakamatautau ultrasonic, electromagnetic ranei e waatea ana. Ko te whakamatautau ka whakamahia me nga rohe tirotiro ka whakatauhia e te kaiwhakanao me te kirimana kaihoko.

4.Flaring Test
Mena he whakaritenga motuhake mo te maemaa rino, ko nga tikanga whakamatautau me nga rohe whakaae ka whakatauhia e te kaiwhakanao me te kirimana kaihoko.
