IP RATINGS
l
The IP (Ingress Protection) rating given to an enclosure states the degree of protection it offers by means of two digits.
A summary of these is shown below; for a more detailed definition, see IEC 529: 1989, BS EN 60529: 1992.
The letter X can be used in place of the first or second digit to
indicate that tests have either not been made or are not applicable.
N0TE:
In the event of additional holes being drilled/pierced or knockouts removed,
suitable measures should be taken to restore the products to the original
ratings.
IEC 529, BS EN 60529 does not apply to protection against the risk of
explosion or conditions such as humidity, corrosive gases, fungi or vermin.
n certain cases equipment designed to be mounted in an enclosure will
contribute towards the stated IP rating (eg pushbuttons mounted in an
nclosure). Different parts of enclosures can have different degrees of
protection and still conform to the standard (eg enclosures with pre-drilled
conduit entry).
FIRST DIGIT
Protection against solid foreign objects and access to hazardous parts
The first digit covers protection against penetration by solid objects, which includes
hands and tools such as screwdrivers.At the lowest of seven levels, 0, no protection
is offered, either of the equipment itself from damage by intrusion or of a person
contacting live or moving parts. At the highest, 6, there shall be no entry of dust.
SECOND DIGIT
Protection against ingress of water
The second digit covers the degree of protection against the entry of water, on a
progressive scale. For example, number 1 indicates that dripping water shall have no
harmful effect, and number 6, that water projected in powerful jets against the
enclosure from any direction shall have no harmful effects.
