An IP65 rating can be determined using the
adjacent table and example:
• The first number of the rating example,
6, in the gray column means the enclosure
is dust tight
• The second number of the rating example,
5, in the blue column means the enclosure is
protected against jets of water
The IP rating system was established by the
International Electrotechnical Commission (IEC),
an organization for international standards and
conformity assessment. The IEC collaborates
closely with the International Organization for
Standardization (ISO). A complete description
of the IP ratings and associated tests is found
in IEC Publication 529. Although these ratings
were initially developed as a way to classify
enclosures, they now provide a convenient,
practical way to compare levels of sealing.
Many electrical products have an Ingress
Protection (IP) rating which identifies the
environmental factors needing consideration
prior to the product’s installation.
This is important when deciding when to mount
products in a dry and clean environment versus
a wet and/or dusty environment. The IP rating
indicates the degree of protection provided.
The numbers following IP represent levels of
sealing and can range from no protection to
full protection against dust and water.
The table provides a description of the
protection at each level.
