1.1 This specification covers a group of general requirements common to several wrought product specifications. Unless otherwise specified in the purchase order, or in an individual specification, these general requirements shall apply to copper and copper-alloy tube supplied under Specifications B68, B75, B135, B466/B466M, and B743.

Note 1—This specification B251 is the inch-pound companion to B251M; therefore, no SI equivalents are presented in the specification.
