Abstract

This specification covers seamless round and rectangular including square copper alloy tube in straight lengths. The tempers of drawn tube shall be designated as light-drawn, drawn, and hard-drawn. Light-drawn temper shall be used only when a tube of some stiffness but yet capable of being bent is needed. Drawn temper, which is most commonly used where there is no specific requirement for high strength on the one hand, shall be utilized for general purposes and or for bending qualities on the other. Hard-drawn temper shall be used only where there is need for a tube as strong as is commercially feasible for the sizes indicated. For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. Expansion test shall be performed on the rounded tube and shall show no cracking or rupture visible to the unaided eye. Both annealed and drawn tempers shall withstand, after proper cleaning, an immersion in standard mercurous nitrate solution for a certain amount of time without cracking. Materials shall then be removed from the solution and shall be wiped free of excess mercury and shall then be examined for cracks. The specimen shall undergo the eddy-current testing which is the standard nondestructive test. The specimen shall undergo the pneumatic test which subjects the tube to an internal air pressure making sure that it must not show evidence of leakage. The test method used shall provide for easy visual detection of any leakage, such as by immersion of the tube under water or by the pressure differential method. Annealed tube shall be either bright annealed or acid cleaned after final annealing operations.

A Alloy Designations of Specification B 135 63, which was published in the 1966 Book of ASTM Standards, Part 5.

1.2 This specification is the inch-pound companion to Specification B 135M; therefore, no SI equivalents are presented in the specification.

1.3 WarningMercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPAs website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. (See 10.1.)

1.4 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.
