Te Kowiri tira, te Rau, te Pereti rānei: Me pēhea te Tauwhāiti Tika

Kupu Whakataki

Ko te rerekētanga i waenganui iKowiri tira kore waikura vs Rau vs Peretie hangai ana ki te āhua tuku, te whānuitanga matotoru, te ara tukatuka me te tikanga hanga e whakaarohia ana. Ko te koiri he rauemi hurihuri papatahi tonu e takai ana i te uho. Ko te rau he rauemi papatahi kua tapahia ki te roa kua tohua hei piko, hei tā, hei hanga māmā rānei. Ko te pereti he rauemi papatahi matotoru e whakamahia ana mō ngā taputapu pēhanga, ngā wāhanga hanganga, ngā tāke, te miihini me te whakarewa taumaha. Me tohu e ngā kaihoko te āhua o te hua nā te mea kāore i te ōrite te whānui, te roa, te papatahi, te manawanui matotoru, te whakaotinga mata, te takai me ngā tikanga tirotiro.

Ngā Whakaaro Matua:Kōwhiria he koiri mō te hanga tonu, te tapahi, te hanga hurihuri me te tā nui-rahi. Kōwhiria he pepa ina hiahiatia he rahinga papatahi, he āhua whakahaere me te hanga watea. Kōwhiria he pereti ina whakahaerea te hoahoa e te pakari o te hanganga, te pupuri pēhanga, te miihini taimaha, te whakarewa nui rānei. Ko te ASTM A240 te tikanga e tautuhi ana i ngā whakaritenga matū me te miihini mō te pereti maitai kore waikura, te pepa me te rīpene, ko te ASTM A480 ia e whakarato ana i ngā whakaritenga whānui pēnei i ngā rahinga, ngā manawanui, ngā whakaotinga, ngā mōhiohio whakamātautau me te tono.

He rerekē te whakamahinga o ngā kupu pēnei i te pepa me te pereti puta noa i ngā mākete. Kaua te matotoru anake e waiho hei whakamāramatanga hoko. Me whakaatu i roto i te ota te āhua tuturu o te hua, te huarahi hanga, te manawanui āhua, te āhua o te taha me te whakaotinga e hiahiatia ana e te tukanga o muri mai.

He aha ngā koiri, rau me ngā pereti rino kore waikura?

Kowiri tira kore waikura
