ASTM A709 Sehlopha sa HPS 50W poleiti ea tšepe

ASTM A709 E fumaneha ka limaraka tse tloaelehileng: 36, 50 le 50W. E fumaneha ka limaraka tse sebetsang hantle haholo: HPS 50W le HPS 70W. Li-certification tse ikhethang tsa ASTM le AASHTO lia fumaneha. Bareki ba ka hlakisa limaraka tsa A709 ho fihlela tlhoko ea tlhahlobo ea Charpy bakeng sa libaka le boemo ba leholimo bo itseng.
