ASTM A283 kila

Hoʻolālā ʻia ʻo ASTM A283 e like me ke ʻano o ka pā hao kalapona no ke kumu hana maʻamau, he haʻahaʻa haʻahaʻa kēia kila a me ka ikaika tensile waena, loaʻa iā ia he 2 mau māka kila (Papa C, Papa D). No ka pā kila i hana ʻia mai nā wili a i ʻole ka mālama ʻana i ka wela, koi ʻia kahi hoʻāʻo hou no ka hoʻomaha ʻana i ke kaumaha, maʻamau ma hope o ka hoʻoheheʻe ʻia ʻana o ka coil kila, ka nānā ʻana, conditining, pono ka mālama wela ma mua o ka lawe ʻana. inā pono ʻoe e kūʻai i ka pā kila ASTM A283, e kelepona mai iā mākou i kēia manawa.
