ASTM A153 ndi ASTM A123 ndi miyeso iwiri yosiyana yopangidwa ndi American Society for Testing and Materials (ASTM International), makamaka yokhudzana ndi kutsimikizika kwachitsulo chamalata.Zotsatirazi ndizofanana zawo zazikulu ndi zosiyana:
Zofanana:
Malo omwe amamangidwira: Onsewa amaphatikiza galvanizing ya dip yotentha, yomwe imaphatikizapo kumiza zitsulo mu zinc wosungunuka kuti apange zokutira zoteteza za zinki.
Kusiyana:
Kufikira koyenera:
ASTM A153: Zoyenera kwambiri zokometsera zotentha za tizigawo tating'ono, mabawuti, mtedza, zomangira, ndi zina zambiri zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana.
ASTM A123: Imagwiritsidwa ntchito makamaka kuzinthu zazikulu kapena zofunika kwambiri, monga mapaipi, zopangira, zotchingira, zomangira zitsulo, ndi zina zambiri, zokhala ndi zofunika kwambiri pazosanjikiza za zinc.
Makulidwe a zokutira:
ASTM A153: Chophimba chomwe chimafunikira nthawi zambiri chimakhala chochepa kwambiri ndipo nthawi zambiri chimagwiritsidwa ntchito pazigawo zomwe zimakhala ndi zofunikira zochepa kuti zisawonongeke.
ASTM A123: Zofunika zokutira nthawi zambiri zimakhala zolimba, zomwe zimafuna makulidwe okulirapo kuti apereke moyo wautali wokana dzimbiri.
Njira yodziwira:
ASTM A153: Njira yoyesera yomwe imagwiritsidwa ntchito ndiyosavuta, makamaka yokhudzana ndi kuyang'ana kowoneka ndi kuyeza makulidwe a zokutira.
ASTM A123: yolimba kwambiri, makamaka kuphatikiza kusanthula kwamankhwala, kuyang'ana kowoneka, kuyeza makulidwe a zokutira, ndi zina zambiri.
Munda wa ntchito:
ASTM A153: Yoyenera pazigawo zing'onozing'ono, mabawuti, mtedza, ndi zina.
ASTM A123: Yoyenera kuzimanga zazikulu komanso zofunika kwambiri, monga zomangira, milatho, njanji, ndi zina.
Ponseponse, kusankha kwa mulingo woti mugwiritse ntchito kumatengera zomwe mukufuna kugwiritsa ntchito.Ngati nyumba zazikuluzikulu zikukhudzidwa kapena zimafuna kukana kwa dzimbiri, nthawi zambiri amasankhidwa kuthirira kotentha koviika molingana ndi muyezo wa ASTM A123.
