No. 488 Qingda Road, Heqing Industry Zone Ref. No.: MH-110705 Pudong New Area Shanghai Phone : 86-021-589766262 China FAX : 86-021-58976603 To whom may it concern ; Subject : Hydraulic test of tube Hydraulic test of tube of our copper tubes shall be conducted under conditions Test hydrostatic pressure shall be conducted hydraulic test pressure computed by the following formula shall be applied, the last time for 10s-15s. But, it is not necessary to test under 6.86Mpa (70kgf/cm²) except for special requirement. 2S・t P= D-0.8t Where: P-Test hydrostatic pressure, MPa (kgf/cm²); t- Wall thickness of tube, mm; D-Outer diameter of tube ,mm; S-Allowable stress of material, allowable stress of

pure copper is 41.2Mpa (4.2kgf/mm²) And, we obtained following test result from our copper tube "M", which is a temper of copper tube and meaning of the temper is "O"(soft) of JIS H3300, at our factory on the 4th of December, 2003. This is in reference to attached “Analysis Report” in Chinese.

And, we translated the descriptions of “Analysis Report” into English.
