Ngā Whakaritenga Hangarau mō ngā Ngongo Rino Waro Pirau wera-tuku
Ngā Ngongo NBR 5590
He mea hanga, he mea tuku mai hoki ēnei me ngā tuitui, kāore rānei, he mea hanga mō te kawe i ngā wai kore-waikura. E whakamahia ana ēnei i roto i ngā taputapu miihini me ngā taputapu miihini, engari ka taea te whakamahi mō te kawe i te mamaoa, te wai, te hau me te hau kōpeke.
I whakaputaina te Paerewa o Brazil – NBR 5590 mō ngā ngongo maitai, e te Brazilian Association of Technical Standards, ABNT, me te whāinga ki te whakahaere i te hanga me te tuku i ngā Ngongo Whakarite. Ka hangaia ēnei ngongo ki te maitai waro, me te whakarewa roa, mangu, whakakanapa rānei, me te whāinga ki te kawe i ngā wai kore-waikura i raro i te pēhanga, te pāmahana me ngā tono miihini motuhake, ahakoa e whakamahia ana hoki mō ngā tono noa o te kawe i ngā kohu, ngā hau, te wai me te hau kōpeke. Ka whiwhi ēnei ngongo maitai i te tiwhikete ā-ture i muri i te whakahaere i ngā whakamātautau taiwhanga haumaru me te whai hua. Me ngā ine motuhake, ka whakamahia tēnei momo ngongo i roto i ngā tono miihini me te miihini. Paerewa rite: ASTM A53.
