1.1 This specification establishes the requirements for seamless COCf water tube suitable for general plumbing, similar applications for the conveyance of fluids, and commonly used with solder, flared, or compression-type fittings. The type of copper water tube suitable for any particular application is determined by the internal or external fluid pressure, by the installation and service conditions, and by local requirements. Means of joining or bending are also factors which affect the selection of the type of tube to be used.
5. Materials and Manufacture
5. 1 Materials:
5.1 1 The material of manufacture shall he a form of such purity and soundness as to he suitable for processing into the products prescribed herein.
5.1.2 When specified in the contract or purchase order that heat identification or traceability is required, the purchaser shall specify the details desired.
Note 4—Because of the discontinuous nature of the processing of castings into wrought products, it is not practical to identify specific casting analysis with a specific quantity of finished material.
5.2 Maizufiicturer:
5.2.1 The product shall be manufactured by such hot- working, cold-working. and annealing processes as to produce a uniform wrought structure in the finished product.
5.2.2 The product shall be hot- or cold-worked to the finished size and subsequently annealed, when required, to meet the temper properties specified.
5.2.3 Tube, when furnished in coils, shall he annealed after coiling.
5.2.4 Tube, when furnished in straight lengths, shall normally be in the drawn temper. Upon agreement between the manufacturer or supplier and the purchaser, the manufacturer shall have the option to supply annealed straight length tubing.
6. Chemical Composition
6. 1 The material shall conform to the chemical composition requirements in Table 2 for the copper [alloyl UNS No. designation if specified in the ordering information.
6.2 These composition limits do not preclude the presence of other elements. By agreement between the manufacturer and the purchaser. limits may be established and analysis required for unnamed elements.
7. Temper
7. 1 The standard tempers for products described in this specification are given in Table 3.
7.1.1 Annealed tempers 060, and 050.
7.1.2 Drawn temper H58.ASTM B88 pdf download.
