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 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The tempers of drawn tube shall be designated as light-drawn H55drawn H58and hard-drawn H Caution should be taken when handling mercury and mercury containing products. Ten atm are specified having the following nominal compositions:. For atm combination of diameter and wall thickness not covered under hard-drawn temper, the values given for drawn temper shall be used.

ASTM B / BM – 17 Standard Specification for Seamless Brass Tube

Nondestructive tests such as eddy-current test, hydrostatic test, and pneumatic test shall be done as well. Drawn temper is for general purposes and is most commonly used v135 there is no specific requirement for high strength on the one hand or for bending qualities on the other.

The tempers of annealed qstm shall be designated as light anneal O50 and soft anneal O Ten alloys are specified having the following nominal compositions: Hard-drawn temper is used only where there is need for a tube as strong as is commercially feasible for the sizes zstm.

Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. This specification covers seamless round and rectangular including square copper alloy tube in straight lengths. The following copper alloys are specified and classified according to their nominal compositions:
