4 .8 I P pr ot e ct ion
Each par t of a Sim rad aut opilot syst em has a t wo digit s I P
prot ect ion code.
The I P rat ing is a m et hod t o classify t he degr ee of prot ect ion
against solid obj ect s, wat er ingress and im pact afforded by
elect r ical equipm ent and enclosures. The sy st em is recognized in
m ost European count ries and is set out in a num ber of Brit ish
and European st andards.
The fir st code num ber descr ibes t he prot ect ion against solid
obj ect s, and t he second num ber describes t he prot ect ion against
liquids.
