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.
