Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes indicated.
The tempers of annealed tube shall be designated as light anneal O50 and soft anneal O Ten alloys are specified having the following nominal compositions:. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For any combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used. A mercury nitrate test shall be done to detect and remove mercury vapor.
The following copper alloys are specified and classified according to their nominal compositions: This abstract is a brief summary of the referenced standard.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Link to Active This link will always route to the current Active version of the standard. Drawn temper is for general purposes and is most commonly astmm where there is no specific requirement for high strength on the one hand or for bending qualities on the other.
Combining values from the two systems may result in non-conformance with the standard.
The tubes shall undergo mechanical tests such as tension test, Rockwell hardness test, and expansion test in order to determine certain properties such as tensile strength and hardness. The tempers of v135 tube shall be designated as light-drawn H55drawn H58and hard-drawn H ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well.

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. Ten alloys are specified having the following nominal compositions: Light-drawn bending temper is used only when a tube of some stiffness but yet capable of being bent is needed. This specification covers seamless round and rectangular including square copper alloy tube in straight lengths.
