Gives principles and presentation for mechanical, hydraulic, pneumatic, topographic, block, circuit, piping, interconnection and supplementary diagrams.

This part of BS 5070 gives recommendations for the practice to be followed in preparing mechanical, process and fluid flow diagrams. It covers all aspects of diagram representation except the choice of symbols for particular components; this is the subject of BS 1553 and other relevant standards giving symbols for specific industrial use.

This part of this standard should always be used in conjunction with BS 5070-1 and the relevant symbol standards when preparing mechanical, process and fluid flow diagrams.

NOTE 1 The relevant part of BS 5775 should be complied with for the correct application of units and symbols for quantities.

NOTE 2 British Standards detailing graphic symbols for use in engineering diagrams are listed in Appendix B.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
