Annotation of standard text ASTM B228-11a(2021) :

This specification covers bare concentric-lay-stranded conductors made from bare round copper-clad steel wires for general use for electrical purposes. Conductors are classified as follows: Grade 40 HS, Grade 30 HS, and Grade 30 EHS. The numbers and diameters of the wires in the concentric-lay-stranded conductors shall conform to the requirements prescribed. Tests for physical and electrical properties of wires composing concentric-lay-stranded conductors made from copper-clad steel wire shall be made before stranding.
