Reference should bemade to BS EN 60529:1992 for full details concerning test and acceptance criteria.
A coding system is defined by BS EN 60529 for the classification of degrees of protection provided by enclosures of electrical equipment against solid objects and
water.This coding comprises the letters ‘IP’ followed by a two digit code as follows:-
IP 6 5
iaga noitcetorp senifeD
stcejbo dilos tsniaga noitcetorp senifeD
nst water.
and access to hazardous parts.
Degrees of protection indicated by a number up to and including ‘6’ implies compliancewith the requirements for all lower numbers. For a codewith a second digit of
7 or 8, a second codemust be stated to specify protection against water jets or spray. eg IP66/IP67.
