ASTM D7803

ʻO nā alahaka kekahi laʻana o nā hana kūkulu i hana pinepine ʻia mai ke kila wela wela. Pehea e ʻaʻahu ai i kēia kila me ka ʻole o ka hoʻopili ʻana o ka ʻōnaehana pauka i wehewehe ʻia i ka maʻamau ASTM hou.

ʻO ka maʻamau hou, ASTM D7803, "Practice for Preparation of Zinc (Hot-Dip Galvanized) Coated Iron and Steel Product and Hardware Surfaces for Pauka Pauka” uhi ʻia ka hoʻomākaukau ʻana o ka ʻili a me ka hoʻomaʻamaʻa ʻana i ka wela o nā huahana hao a me ke kila a me nā lako i pena ʻole ʻia a i uhi ʻole ʻia ma mua (Practice D6386).

"Ua hoʻonui ʻia ka hoihoi i ka uhi pauda no ka mea ʻaʻohe ona mea hoʻohuihui kūlohelohe ma luna o ka pale corrosion, e like me ka uhi galvanized no kala like 'ole a me ka helehelena.” Ua ʻike ʻo Langill e ʻimi nei ʻo D01.46 i nā mea uhi pauda a me nā mea nānā e kōkua i nā hana maʻamau.
