ASTM B – 18 Standard Specification for Seamless Copper Tube for Medical Gas Systems

The value for the Rockwell hardness number of each specimen shall be established by taking the arithmetical average of at leastthree readings. 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. Seamless copper tube for medical gas systems shall be furnished in the H58 Drawn General Purpose temper. 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.

After washing and drying, the tube shall be immediately capped, plugged, 0r otherwise scaled 0r closed at both ends. The manufacturer or supplier and the purchaser may conduct the final inspeciton simultaneously by mutual agreement.

Theoretical wights for purposes of caculating weights, cross sections, and so forth, the density of the copper shall be taken as 0. When specified in the purchase order or contract. Test specimens conforming to type No. Above the yield strength, the movement per minute of the testing machine head undgr load should not exceed 0. Product that fails to conform to the requirements of this specification may be rejected.
