Tension test determinations need not be made except when indicated by the purchaser at the time of placing the order. Tension test and N819 hardness test shall be performed to determine the tube’s tensile strength and hardness, respectively.
Test specimens conforming to type No. This abstract is a brief summary of the referenced standard. Other information maybe included atthe 0ption ofthe manufacturer.
This specification establishes the requirements for two wall thickness schedules of specially cleaned, straight lengths of seamless copper tube, identified as Types K and L, suitable for medical gas systems.
When specified in the contract or purchaser order the purchaser shall be furnished certification that samples representing each lot have been tested or inspected as directed in this specification and requirements have been met. Tension test results on material covered by this specification are not seriousle affected by variations in speed of testing. The result sof this retest shall comply with the specified requiremqnts.
The results of the tests on both of these specimens shall meet the specified atm. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The specification number shall be shown when specified.
Number of Tests and Retests Chemical Analysis-Atleast two replicate analyses of each element with a limiting value shall beconducted. A superscript ast e indicates an editorial change since the last revision or reapproval.
Tension test specimens shall be of the full section of the tube and shall conform to the requirements of 6. 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.

Types K and L tube are defined in Specification B After washing and drying, the tube shall be immediately capped, plugged, 0r otherwise scaled 0r closed at both ends.
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. 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.
Drawn temper tube is suitable for use with capillary solder joint fittings for brazing. Packaging and B89 Marking The product shall be separated by size,composition,and temper and prepared for shipment in such a manner as to ensure acceptance by common carrier for transportation at the l0west rate applicable and to afiord protection from the normal hazards ol transportation.
The deviation aastm roundness is”measured as the difierence between major and minor diameters as determined at any one cross section of the tube. The manufacturer or supplier and the purchaser may conduct the final inspeciton simultaneously by mutual agreement. The product shall be manufactured by such hot working necessary to convert the billet to a tubular shape and cold worked to the finished size.
The tube shall be marked with any of the following in color appropriate to the tube type: The legend shall include the type of tube, name or lrademark of the manufacturer or both, and the country of origin.
