ASTM B508-08

Standard Specification for Copper Alloy Strip for Flexible Metal Hose

ABSTRACT
This specification covers welded copper-nickel alloy pipes produced from Copper Alloy UNS Nos. C70600 and C71500 for general engineering applications. Pipes may be produced in any one of the following tempers: as-welded from annealed sheets, strips, or plates (WM50); as-welded from cold-worked sheets, strips, or plates (WM00, WM01, WM02, and so forth); welded and annealed (WO50); welded, light cold drawn (WR00) or hard cold drawn (WR04), and stress relieved; or fully finished as annealed, light drawn (WH00) or hard drawn (WH04), and stress relieved. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (outside diameter, specific and stock lengths, wall thickness, squareness of cut, and roundness), mechanical (tensile and yield strengths, and elongation), and chemical composition requirements. Specimens shall also undergo nondestructive tests such as radiographic examination, eddy-current test, and hydrostatic test.
SIGNIFICANCE AND USE
For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E 29:
Property% Rounded Unit for Observed or
Calculated Value  Chemical compositionnearest unit in the last right hand place

SCOPE
1.1 This specification establishes the requirements for annealed copper-alloy strip for the manufacture of flexible metal hose produced from Copper Alloy UNS Nos. C41100 and C50500.
1.1.1 The nominal compositions are as follows:
Copper Alloy
UNS No.CopperZincTin  C4110091.08.50.5  C5050098.7...1.3
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Grain size is given in SI units.
1.3 The following precautionary statement pertains only to the test method portion, Section 13, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
