Sampling—The lot size, portion size, and selection of sample pieces shall be as follows: The axis of the tensile specimen shall be located at any point midway between the center and the surface of solid forgings and at any point midway between the inner and outer surfaces of the wall of hollow forgings, and shall be parallel to the direction of greatest grain?

Used for forgings requiring extensive machining, architectural hardware, fittings, mechanical components, specialty fasteners. The following copper and copper alloys are included: Dimensions and Permissible Variations The following copper and copper alloys are included: It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Combining values from the two systems may result in non-conformance with the standard. C, C, C, C, Cthe sum of results shall be Soldering is rated as “excellent”, brazing is rated as “good”, oxyacetylene welding is “not recommended”, gas shielded arc welding is “not recommended”, coated metal arc welding is “not recommended”, spot welding is “not recommended”, seam welding is “not recommended”, and butt welding is rated as “fair”.
