Description / Abstract:
This standard details the requirements for ingress protection of
luminaires in roadway and area lighting equipment, installed for
their intended use and specified by end user. While these
requirements are suitable for most types of lighting equipment, it
should not be assumed that all the listed degrees of protection are
applicable to a particular type of equipment. The manufacturer of
the equipment should be consulted to determine the degrees of
protection available.
The adoption of this standard should promote uniform methods of
describing the protection provided by the lighting equipment
(luminaire) enclosure.
NOTE—The basis for this standard are the documents IEC 60529,
Degrees of protection provided by enclosures; and IEC 60598-1,
Luminaires, general requirements, and tests, Section 9,
"Resistance to dust, solid objects and moisture." Tables 1, 2, and
3, in particular, are based on IEC 60529.
The type of protection covered by this standard is as
follows:
a) Protection of persons against contact with, or approach to,
energized electrical components inside the light fixture
(luminaire) enclosure, and protection of the equipment against
ingress of solid foreign bodies
b) Protection of equipment inside an enclosure against harmful
ingress of water, solid foreign objects or dust
It should be noted that the IP rating of a luminaire has no
bearing on its Dirt Depreciation characteristics. Testing is
performed on new luminaires and is not an indicator of the life or
reliability of the luminaire during its service life. Some
components such as seals and gaskets deteriorate over time with
exposure to heat and the environment and should be evaluated
separately.
