    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.
