Note 2-Drawn tempertube is suitable for use with capillary solder joint fittings for brazing.

Product: Copper Tube ASTM B819 Type K Specification

The manufacturer or supplier and the ast may conduct the final inspeciton simultaneously by mutual agreement. 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.

Referenced Documents purchase separately The astj listed below are referenced within the subject standard but are not provided as part of the standard. Material-The materials of manufacture shall be a cast billet of Copper Alloy UNS Cl of such purity and soundness as to be suitable for processing into the products prescribed herein. Manufacture-The product shall be manufactured by such hot working necessry to convert the billet to a tubular shape and cold worked to the finished size.

This standard does not purport sstm address all of the safety concerns, if any, associated with its use.

Limits for unnamed elements may be established by agreement between the manufacturer or supplier and the purchaser. 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. Tension test and Rockwell hardness test shall be performed to determine the tube’s tensile strength and hardness, respectively.

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


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

After washing and drying, the tube shall be immediately capped, plugged, 0r otherwise scaled 0r closed at both ends. Drawn temper tube is suitable for use with capillary solder joint fittings for brazing. A convenient method of indicating that these tests are to be made is to state that “Test Procedure T” is required see 4. Dimensions, Mass asrm 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.

TES Certificates are available for all product upon request at the time of order. 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.

Seamless copper tube for medical gas systems shall be furnished in the H58 Drawn General Purpose temper. 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. The deviation b189 roundness is”measured as the difierence between major and minor diameters as determined at any one cross section of the tube.

The result sof this retest shall comply with the specified requiremqnts. Squareness of Cut-fhe departure from squareness of the end of any tube shall not exceed more than 0.

Copper Tube ASTM B Type K Specification

The following are recommended practices lor cleaning, butthe produceris nota limited to these procedures. The legend shall include the type of tube, name or lrademark of the manufacturer or both, and the country of origin.


The value for the Rockwell hardness number of each specimen shall be established by taking the arithmetical average of at leastthree readings. Steam SoplventWashing-Washing by flushing,with Steam containing Stoddard S0lvent 0r its equivalent, rinsing thoroughly with celansteam,andpurgingwithhotordryair.

Historical Version s – view previous versions of standard. Failur of more than on specimen to meet the b81 requirements for aparticular property shall be the cause for rejection of the entire lot. 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.


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. A superscript epsilon e indicates an editorial change since the last revision or reapproval. The specification number shall be shown when specified. Packaging and Package Marking Awtm product shall be separated by size,composition,and temper and prepared for ast in such a manner as to ensure acceptance by common carrier for transportation at the l0west rate applicable and to afiord protection zstm the normal hazards ol transportation.

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. Theoretical wights for purposes of caculating weights, cross sections, and so forth, the density of the copper shall be taken as 0.

The tube shall be marked with any of the following in color appropriate to the tube type:
