ASTM A320
Te whānuitanga
I whakaaetia tuatahitia i te tau 1948, ko te tohu ASTM A320 e hipoki ana i te koranu rino me nga taonga kowiri tira mo te ratonga pāmahana iti. Ko tenei paerewa e hipoki ana i nga kaho kua whakatakahia, kua hangahia, kua werohia ranei nga tutaki kua whakapakeketia, nga raka, nga tira, nga kaitao, me nga pou tiu e whakamahia ana mo nga oko pehanga, nga maru, nga kopa me nga taputapu. Pērā i te whakapūtātanga ASTM A193, ki te kore e tauwhāitihia, ko te raupapa miro 8UN kua tohua ki runga i te taapiri nui ake i te 1" te whanui.
Kei raro nei he whakarāpopototanga taketake o etahi o nga reanga noa i roto i te whakaritenga ASTM A320. He maha atu nga reanga iti noa o te ASTM A320 kei te noho, engari karekau i te whakamaarama i raro nei.
