145 / 148
Example:
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.
