Introduction
This Technical Report specifies symbols for use in drawings for lightning protection systems
If necessary, additional symbols may be used for other important elements of the object to be protected.
These symbols should be simple and they have to be explained in a legend in the LPS design drawings.
In case of an isolated protection system (see IEC 62305-1 and IEC 62305-3) this has to be stated in the LPS
design drawings including required separation distances.
In case of preparing a coloured kind of drawing, the colours should be used as follows:
– building black,
– lightning protection red,
– metal sheets green,
– metal structure blue.
