BS 2871 Copper Tubes Table X, Y and Z - Working Pressures vs. Size
The copper used in the manufacture of tubes is phosphorus deoxidized copper Cu-DHP defined by British Standard BS. 6017: 1981. This also corresponds to the ISO denomination Cu-DHP.
The minimum copper content is 99.85% and the residual phosphorus content is between 0.013 and 0.050%. This deoxidized copper is not affected by reducing atmospheres and consequently is well suited to welding and brazing. The density of copper is 8.9 g/cm3. its melting point is 1083 oC and its coefficient of linear expansion is 16.8×10-6 per oC (ranging 20 oC - 100 oC).
Note! - this standard is replaced with EN 1057 - Copper tubes for water and gas in sanitary and heating applications
