maitai ASTM A513He paipa me he ngongo rino waro me te koranu i hangaia mai i te rino hurihuri-wera, hurihuri-matao rānei hei rauemi mata mā te tukanga whakarewa ātete (ERW), e whakamahia whānuitia ana i roto i ngā momo hanganga miihini katoa.
Ka taea te wehewehe i te Momo 1 ki te 1a me te 1b.
Momo 1a (AWHR): "kua oti te whakarewa" mai i te maitai kua hurihia ki te wera (me te tauine mira).
Ka whakarewahia tika tēnei momo paipa mai i te maitai wera-hurihuri me te waikura rino (te unahi mira) i hangaia i te wā e huri ana. He maha ngā wā ka whakamahia tēnei momo paipa i ngā mahi kāore e tino hira te kounga o te mata nā te mea kei roto i te mata te unahi mira.
Momo 1b (AWPO): "kua oti te whakarewa" mai i te maitai kua hurihia weratia, kua pania ki te hinu (kua tangohia te unahi mira).
He mea whakarewa tēnei momo paipa mai i te maitai wera kua whakapūkarahia, kua pania ki te hinu, ā, ko tōna āhuatanga ko te tango i te unahi mira. Ehara i te mea ka tangohia noa e te maimoatanga whakapūkara me te paninga hinu te waikura o te mata, engari ka whakaratohia hoki he tiaki waikura me te hinu whakahinuhinu i te wā e tukatukahia ana, kia pai ake ai tēnei paipa mō ngā tono e hiahia ana ki tētahi mata ma, ki ngā āhuatanga tukatuka paku piri rānei.
