ASTM A153 iyo ASTM A123 waa laba heerar oo kala duwan oo ay soo saartay Society American for Testing and Materials (ASTM International), oo inta badan la xidhiidha qeexida birta galvanized. Kuwa soo socda waa isku ekaanshaha iyo kala duwanaanshahooda ugu waaweyn:
Waxyaalo la mid ah:
Meesha la beegsanayo: Labaduba waxay ku lug leeyihiin galvanizing-kulul, taas oo ku lug leh gelinta alaabta birta ee zinc dhalaalaysa si ay u sameeyaan dahaarka ilaalinta zinc.
Kala duwanaanshaha:
Baaxadda lagu dabaqi karo:
ASTM A153: Inta badan waxay ku habboon tahay galvanizing-kulul ee qaybo yaryar, boolal, nuts, boolal, iwm oo loo isticmaalo alaabooyin kala duwan.
ASTM A123: Inta badan waxaa lagu dabaqi karaa dhismayaasha waaweyn ama ka muhiimsan, sida tuubooyinka, dhejiska, darbiyada, dhismayaasha birta, iwm, oo leh shuruudo adag oo loogu talagalay lakabka zinc.
Dhumucda dahaarka:
ASTM A153: Daahan guud ahaan loo baahan yahay waa yara dhuuban waxaana badanaa loo isticmaalaa qaybaha shuruudaha hoose ee iska caabbinta daxalka.
ASTM A123: Shuruudaha dahaarka inta badan waa adag yihiin, waxay u baahan yihiin dhumuc weyn oo daahan si loo siiyo nolol caabbinta daxalka dheer.
Habka lagu ogaanayo:
ASTM A153: Habka tijaabada ee la isticmaalay waa mid fudud, inta badan ku lug leh kormeerka muuqaalka iyo cabbirka dhumucda dahaarka.
ASTM A123: Aad u adag, sida caadiga ah oo ay ku jiraan falanqaynta kiimikada, kormeerka muuqaalka, cabbirka dhumucda dahaarka, iwm.
Goobta codsiga:
ASTM A153: Ku habboon qaybo yaryar qaarkood, boolal, nuts, iwm.
ASTM A123: Waxay ku habboon tahay dhismayaasha waaweyn iyo kuwa ka muhiimsan, sida dhismayaasha dhismaha, buundooyinka, dariiqyada ilaalada, iwm.
Guud ahaan, doorashada heerka heerka la isticmaalayo waxay ku xiran tahay shuruudaha codsiga gaarka ah. Haddii dhismayaal waaweyni ay ku lug leeyihiin ama u baahan yihiin iska caabin daxalka sare leh, galvanizing-kulul sida waafaqsan heerka ASTM A123 ayaa badanaa la doortaa.
