Annotation of standard text ASTM B231/B231M-23 :
This specification covers aluminum 1350-H19, 1350-H16 or -H26, 1350-H14 or -H24, and 1350-H142 or -H242, bare concentric-lay-stranded conductors constructed with a straight round central wire surrounded by one or more layers of helically layered wires. Conductors are classified as Class AA for bare conductors usually used in overhead lines; Class A for conductors to be covered with weather resistant materials, and for bare conductors where greater flexibility than is afforded by Class AA is required; Class B for conductors to be insulated with various materials such as rubber, paper, varnished cloth, and so forth, and for the conductors indicated under Class A where greater flexibility is required; and Classes C and D for conductors where greater flexibility is required than is provided by Class B conductors. Aluminum wire employed in Classes AA and A conductors shall be 1350-H19, unless otherwise specified. The temper of conductors of Classes B, C and D shall be designated. The direction of lay of the outer layer shall be right-hand for Classes AA and A and left-hand for other classes. The various classes of concentric-lay-stranded conductors shall conform to the required areas of cross section, numbers, and diameters of wires. The rated strength of 1350-H19 conductors shall be taken as the percent of the sum of the strengths of the component wires, calculated using the nominal wire diameters and the specified minimum average tensile strength given in Specification B 230/B 230M for 1350-H19 wire.
