ASTM B8-11<\/h3>\n

Historical Standard: Standard Specification for Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft<\/h4>\n
\n

ASTM B8<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification covers bare concentric-lay-stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead alloy for general use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires.<\/p>\n

Note<\/span> 1\u2014This specification also permits conductors for use as covered or insulated electrical conductors.<\/p>\n

Note<\/span> 2\u2014Sealed conductors, that are intended to prevent longitudinal water propagation and are further covered\/insulated, are also permitted within the guidelines of this specification.<\/p>\n

1.2 For the purposes of this specification, conductors are classified as follows (Explanatory Note 1 and Note 2):<\/p>\n

1.2.1 Class AA<\/span>\u2014<\/span>For bare conductors usually used in overhead lines.<\/p>\n

1.2.2 Class A<\/span>\u2014<\/span>For conductors to be covered with weather-resistant (weather-proof), slow-burning materials, and for bare conductors where greater flexibility than is afforded by Class AA is required.<\/p>\n

1.2.3 Class B<\/span>\u2014<\/span>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.<\/p>\n

1.2.4 Class C and Class D<\/span>\u2014<\/span>For conductors where greater flexibility is required than is provided by Class B conductors.<\/p>\n

1.3 The SI values for density are regarded as the standard. For all other properties, the inch-pound values are to be regarded as standard and the SI units may be approximate.<\/p>\n
