Introduction
symbols shown below are generally based on BS 7845:1996 , BS 3939 and BS EN 60617
The diagrams are produced using symbols as building block combining functional symbols
with symbols for variability and operation and material.. The number of symbols are very
large and BS EN 60617 includes many fields from power generation to solid state electronics.
The symbols below are just a selection related to the fields related to general engineering provided as a general guide.
For details showing proportions and sizes reference to the standards is necessary
