ASTM A449
ASTM A449 waxay dabooshaa boolal madax, ulo, iyo boolal barroosin oo dhexroor u dhexeeya 1/4 "ilaa 3" in lagu daro. Waa bolt xoog dhexdhexaad ah oo laga soo saaray kaarboon dhexdhexaad ah ama bir daawaha ah oo horumarisa qiyamkeeda farsamo iyada oo loo marayo habka daaweynta kulaylka. Waxaa loogu talagalay codsiyada injineernimada guud.
ASTM A449 waxay ku dhowdahay inay la mid tahay kimistariga iyo xoogga ASTM A325 iyo SAE J429 fasalka 5. Si kastaba ha ahaatee, A449 waa dabacsanaan badan marka loo eego dareenka ah inuu daboolayo dhexroor weyn oo aan xaddidnayn qaabeyn gaar ah.
