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.

The values stated in inch-kpound units are to be regarded as standard, The values given in parentheses are mathematical conversions to Sl units,which are provided for information only and are not considered standard.

This specification establishes the requirements for two wall thickness schedules of specially cleaned, straight lengths of seamless copper tube, identified as Types K aastm L, suitable for medical gas systems. The legend shall include the type of tube, name or lrademark of the manufacturer or both, and the country of origin.

The manufacturer of supplier shall inspect and make tests necessary to verify the product furnished conforms to the requierements of thus spseciflcation. In addition, and as an option, thetube may be charged with dry, oil-free nitrogen bef0re 0rfollowing capping. Theoretical wights for purposes of caculating weights, cross sections, and so forth, the density of the copper shall be taken as 0.

Whenever different tension test results are obtained from both full-size and from machined test specimens, the results obtained from full-size test specimens shall be used to determine conformance to the requirements of this specification. When specified ast, the purchase order or contract.

Where agreement on the Rockwell hardness tests cann0t be reached, the tensile strength requirements of Table 2 shall be the basis for acceptance or rejection.

Manufacture-The product shall be manufactured by such hot working necessry to convert the billet to a tubular shape and cold aastm to the finished size. TES Certificates are available b8119 all product upon request at the time of order. Historical Version s – view previous versions of standard. Mechanlcal tests-For the mechanical tests,a specimen shall be taken from each of the sample pieces bb819 in accordance with The manufacturer or supplier and the purchaser may conduct the final inspeciton simultaneously by mutual agreement.

Other information maybe included atthe 0ption ofthe manufacturer. The cleaner may contain but is not restricted to tri ortetra sodium phosphate, sodiurn carbonate, sodium hydroxide, sodium metasilicate, or sodium orthosilicate plus a wetting agent or any combination of the lore going. Tension test specimens shall be of the b8199 section of the tube and shall conform to the requirements of 6.

Package Marklng-Each shipping unit shall be legibly marked with the purchase order number, metal or alloy designaiion, size, gross and net weight, and name of supplier. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Rejection should be reported to the producer or supplier promptly and in writing. The value for the Rockwell hardness number of each specimen shall be established by taking the b189 average of at leastthree readings.

Above the yield strength, the movement per minute of the testing machine head undgr load should not exceed 0. The tube shall be marked with any of the following in color appropriate to the tube type: The result sof this retest shall comply with the specified requiremqnts. 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.

Reiection and Rehearing Product that fails to conform to the requirements of this specification may be rejected. When specified in the contract or purchase order,the manufacturer or supplier shall furnish to the purchaser a test report showing the results of tests required by this specification. This spesification establishes the requirements for two wall thickness schedules of specially cleaned, straight lengths of seamless coppertube, identified as Types K and 1, suitable for medical gas systems.

The tubes used for medical gas systems shall be cleaned by any of the following recommended methods: Drawn temper tube is suitable for use with capillary solder joint fittings for brazing. The deviation from roundness is”measured as the difierence between 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.

Product that fails to conform to the requirements of this specification may be rejected. This abstract is a brief summary of the referenced standard. 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.

The following safety hazard caveat pertains only to the test method portion of Section dl2 of this specification. Note 2-Drawn tempertube is suitable for use with capillary solder joint fittings for brazing.

ASTM B – 00 Standard Specification for Seamless Copper Tube for Medical Gas Systems

Temper Seamless copper tube for medical gas systems shall be furnished in the H58 Drawn General Purpose temper, as defined in Practice Dimensions, Mass and Permissible Variations For the purp0se of determining conformance with the dimensional requirements specified in this specification, any measured value 0utside the specif ied limiting values for any dimensions may be cause for rejection.

A convenient method of indicating that these tests are to be made is to state that “Test Procedure T” is required see 4. Tension test and Rockwell hardness test shall be performed to determine the tube’s tensile strength and hardness, respectively.

Certification 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. Number of Tests and Retests Chemical Analysis-Atleast two replicate analyses of each element with a limiting value shall beconducted.

This standard does not purport to address all of the safety concerns, if any, associated with its use. The specification number shall be shown when specified.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Limits aztm unnamed elements may be established by agreement between the manufacturer or supplier and the purchaser. The deviation from roundness is”measured as the difierence between g819 and minor diameters as determined at any one cross section of the tube.

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 h819 specification and requirements have been met.
