ASTM B75B75M-2019 pdf free download.Standard Specification for Seamless Copper Tube
1. Scope
1.1 This specification 2 establishes the requirements for seamless round, rectangular, and square copper tube suitable for general engineering applications. 1.1.1 Tubes made from any of the following Copper UNS No. designations shall be supplied unless otherwise specified in the contract or purchase order:1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 The following safety hazard caveat pertains only to the test methods described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility ofthe user ofthis standard to establish appropriate safety, health, and environ- mental practices and determine the applicability ofregulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
6. Material and Manufacture
6.1 Material—The material of manufacture shall be billets, bars, or tube of Copper UNS No. C10100, C10200, C10300, C10800, C12000, or C12200, and shall be ofsuch soundness as to be suitable for processing into the tubular products de- scribed. 6.2 Manufacture: 6.2.1 The tube shall be manufactured by such hot- and cold-working processes as to produce a uniform wrought structure in the finished product. It shall be cold drawn to the finished size and wall thickness. 6.2.2 When cold-drawn temper is required, the final draw- ing operation shall be such as to meet the specified temper. When annealed temper is required, the tube shall be annealed subsequent to the final cold draw.
7. Chemical Composition
7.1 The material shall conform to the requirements in Table 1 for the specified Copper UNS No. designation. 7.1.1 These composition limits do not preclude the presence of other elements. By agreement between the manufacturer or supplier and the purchaser, limits may be established and analysis required for unnamed elements.
8. Temper
8.1 The requirements and size availability of tube in the cold-drawn tempers H55, H58, and H80, as defined in Classi- fication B601, are specified in Table 2 or Table 3. 8.1.1 Rectangular, including square, tube shall normally be supplied only in H58 temper. When requested by the manu- facturer or supplier, and upon agreement with the purchaser, tube may be supplied in H55 temper. For any combination of diameter and wall thickness not listed under H80 temper, the requirements specified for H58 temper shall apply. 8.2 The requirements and size availability of tube in the annealed tempers O50, O60, and O62 as defined in Classifi- cation B601, are specified in Table 2 or Table 3. N OTE 1—The purchaser shall confer with the manufacturer or supplier for the availability of product in a specific temper. N OTE 2—Refer to Appendix X1 for recommended applications based on temper.
15. Nondestructive Test
15.1 The tubes shall be tested in drawn tempers or as drawn before the final-annealed temper unless otherwise agreed upon between the manufacturer and the purchaser. 15.2 Electromagnetic (Eddy-Current) Test: 15.2.1 Each tube up to and including 3 1 ⁄ 8 in. [79 mm] in outside diameter shall be subjected to test. 15.2.2 When tested in accordance with Practice E243, tubes which do not actuate the signaling device of the testing unit shall be considered as conforming to the requirements of the test. 15.3 Hydrostatic Pressure Test—When specified in the con- tract or purchase order, each tube shall be capable of with- standing an internal hydrostatic pressure sufficient to produce a fiber stress of 6000 psi [41 MPa] without leakage. The tube need not be subjected to a pressure gauge reading over 1000 psi [6.9 MPa] unless specifically stipulated in the contract or purchase order. 15.4 Pneumatic Pressure Test—When specified in the con- tract or purchase order, each tube shall be capable of with- standing an internal air pressure of60 psi [400 kPa], minimum, for 5 s without leakage.
