ASTM A283 uamea

ASTM A283 ua mamanuina e avea o se ituaiga o ipu uamea kabon mo faamoemoega lautele, o lenei uamea e maualalo ma le vaeluaga tensile malosi, e 2 sila togi (Vaega C, Vasega D). Mo ipu uʻamea e faia mai coils poʻo le leai foi o se vevela, e manaʻomia se suʻega faʻaopoopo mo lona faʻamalologa o le atuatuvale, e masani lava pe a uma ona faʻafefeteina uʻamea, suʻesuʻega, conditining, togafitiga vevela e manaʻomia aʻo leʻi tuʻuina atu. afai e te manaʻomia le faʻatau ASTM A283 ipu uamea, faʻafesoʻotaʻi mai nei.
