Kua whakaputaina mana te whakahoutanga a Haina mō ngā paerewa o te ao mō ngā pereti me ngā rīpene maitai

I whakaarohia te paerewa kia whakahoutia i te tau 2022 i te hui ā-tau o te Komiti Iti mō ngā Hua Papa Rino/Roro Tonu a ISO/TC17/SC12, ā, i whakarewaina mana i te marama o Poutū-te-rangi 2023. E rua tau me te hawhe te roa o te rōpū mahi tuhi, i reira i tū ai tētahi hui rōpū mahi me ētahi hui ā-tau e rua mō ngā kōrero nui, ā, i te marama o Paenga-whāwhā 2025, i tīmata te putanga tuaono o te paerewa whakahoutia ISO 4997:2025 "Pereti Rino Angiangi Waro Roro Matao Āhua Hanganga".

Ko tēnei paerewa tētahi atu whakahoutanga paerewa o te ao i arahina e Haina i muri i te rironga mai i a Haina te tūranga heamana o ISO/TC17/SC12. Ko te tukunga o te ISO 4997:2025 tētahi atu putanga nui i roto i te whai wāhi a Haina ki ngā mahi paerewa o te ao i roto i te mara o ngā pereti me ngā rīpene maitai i muri i te ISO 8353:2024.

Kua whakapau kaha ngā hua pereti maitai me ngā hua rīpene maitai hanganga waro ki te whakapai ake i te kaha me te whakaiti i te matotoru, kia whakaitihia ai te taumaha o ngā hua whakamutunga, kia tutuki ai te whāinga matua o te penapena pūngao me te whakaiti i ngā tukunga, me te whakatutuki i te ariā whakaputa o te "maitai matomato". Kāore i te whakaritea te putanga 2015 o te paerewa mō te kaha hua e whakamahia whānuitia ana i te mākete o ngā karaehe maitai 280MPa. Hei tāpiri, ko ngā ihirangi hangarau o te paerewa, pērā i te taratara o te mata me te taumaha puranga, kāore e tutuki i ngā hiahia tuturu o te whakaputanga o nāianei. Hei whakarei ake i te whai mana o te paerewa, i whakaritea e te Metallurgical Industry Information Standards Research Institute a Anshan Iron & Steel Co. ki te tono mō tētahi kaupapa mahi paerewa o te ao hou mō tēnei hua. I roto i te tukanga whakahou, i whakatauhia ngā whakaritenga hangarau o te taumata hou i runga i te kōrero tahi me ngā tohunga o Hapani, Tiamana me te United Kingdom mō ngā wā maha, me te whai kia tutuki ngā whakaritenga o te whakaputa me te tirotiro i ia whenua, me te whakawhānui ake i te whānuitanga o te tono o te paerewa. Ko te tukunga o te ISO 4997:2025 "Pereti Rino Angiangi Waro Huri Matao-Whakairoiro" e pana ana i ngā taumata me ngā paerewa hou i rangahauhia, i whakawhanakehia hoki e Haina ki te ao.
