TES Certificates are available for all product upon request at the time of order. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

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

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. The following safety hazard caveat pertains only to the test method portion of Section dl2 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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.

Limits for unnamed elements may be established by agreement between the manufacturer or supplier and the purchaser. 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. Tension test determinations need not be made except when indicated by the purchaser at the time of placing the order. A convenient method of indicating that these tests are to be made is to state that “Test Procedure T” is required see 4.

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. 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.

Theoretical wights for purposes of caculating weights, cross sections, and so forth, the density of the copper shall be taken as 0. The deviation from roundness is”measured as the difierence between major and minor diameters as determined at any one cross section of the tube. The manufacturer of supplier shall inspect and make tests necessary to verify the product furnished conforms to the requierements of thus spseciflcation.

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.

Mill Test Report 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. Packaging and Package 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 following are recommended practices lor cleaning, butthe produceris nota limited to these procedures. 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. Steam SoplventWashing-Washing by flushing,with Steam containing Stoddard S0lvent 0r its equivalent, rinsing thoroughly with celansteam,andpurgingwithhotordryair.

After washing and drying, the tube shall be immediately capped, plugged, 0r otherwise scaled 0r closed at both ends. In addition, and as an option, thetube may be charged with dry, oil-free nitrogen bef0re 0rfollowing capping.

Number of Tests and Retests Chemical Analysis-Atleast two replicate analyses of each element with a limiting value shall beconducted. Mechanlcal tests-For the mechanical tests,a specimen shall be taken from each of the sample pieces selected in accordance with The value for the Rockwell hardness number of each specimen shall be established by taking the arithmetical average of at leastthree readings.

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 requirements. Failur of more than on specimen to meet the specified requirements for aparticular property shall be the cause for rejection of the entire lot.
