Design, manufacture, installation and inspection of pipework subject to internal pressures for industrial and marine systems. Specifically for (a) steam boiler, fuel and hot water, (b) hydraulic, (c) oil fuel, (d) pneumatic and gas, (e) refrigeration and cryogenic. Complementary to BS 806 and BS 5222. See also BS 61.

This British Standard specifies the design, manufacture, installation and inspection of copper and copper alloy pipework subject to internal pressure for industrial and marine systems. The following systems are specifically covered:

1. steam boiler, feed and hot water;
2. hydraulic (water or oil);
3. oil fuel (BS 799);
4. pneumatic and gas;
5. refrigeration and cryogenic.

This standard does not specifically apply to piping systems for petroleum refineries and petrochemical plants, which are covered by BS 3351.

NOTE Users of this standard, when applying it to marine work, should note that it is essential to ensure compliance with such statutory requirements, rules and regulations of the Regulatory Bodies and classification societies concerned. Attention is also drawn to the requirements of BS MA 18, BS MA 51, BS MA 60 and BS MA 67.
