The following safety hazard caveat pertains only to the test method portion of Section dl2 of this specification.

Seamless copper bb819 for medical gas systems shall be furnished in the H58 Drawn General Purpose temper. Tension test determinations need not atsm made except when indicated by the purchaser at the time of placing the order.

The value for the Rockwell hardness number of each specimen shall be established by taking the arithmetical average of at leastthree readings.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Mechanical Properties The tube shall conform to the mechanical property requirements specified in Table 2 when tested in accordance with Test Methods E 18 and E 8, respectively. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but bb819 not provided as part of the standard. Squareness of Cut-fhe departure from squareness of the end of any atsm shall not exceed more than 0.

Tension test and Rockwell hardness test shall be performed to determine the tube’s tensile strength and hardness, respectively. The deviation from roundness is”measured as the difierence b891 major and minor diameters as determined at any one cross section of the tube, Inspection r The manufacturer of supplier shall inspect and make tests necessary to verify the product furnished conforms to the requierements of thus spseciflcation.

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.
