It will remain the responsibility of individual technical committees to decide on the
extent and manner in which, the classification is used in their standards and to define
“enclosure” as it applies to their equipment. However, it is recommended that for
a given classification the tests do not differ from those specified in this standard. If
necessary, complementary requirements may be included in the relevant product
standard. A guide for the details to be specified in relevant product standards is given
in annex B.
For a particular type of equipment, a technical committee may specify different re-
quirements provided that at least the same level of safety is ensured.
This standard deals only with enclosures that are in all other respects suitable for their
intended use as specified in the relevant product standard and which from the point of
view of materials and workmanship ensure that the claimed degrees of protection are
maintained under the normal conditions of use.
This standard is also applicable to empty enclosures provided that the general test
requirements are met and that the selected degree of protection is suitable for the
type of equipment to be protected.
Measures to protect both the enclosure and the equipment inside the enclosure
against external influences or conditions such as
– mechanical impacts
– corrosion
– corrosive solvents (for example, cutting liquids)
– fungus
– vermin
– solar radiation
– icing
– moisture (for example, produced by condensation)
– explosive atmospheres
and the protection against contact with hazardous moving parts external to the enclo-
sure (such as fans), are matters for the relevant product standard to be protected.
Barriers external to the enclosure and not attached to it and obstacles which have
been provided solely for the safety of personnel are not considered as a part of the
enclosure and are not dealt with in this standard.
d) Speakers intended for security applications; these products are covered in the
Standard for Local Burglar Alarm Units and Systems, UL 609; and the Standard for
Household Burglar-Alarm System Units, UL 1023.
1.3 Speakers intended for use with fire alarm systems are covered by Standard for
Speakers for Fire Alarm and Signaling Systems, Including Accessories, UL 1480.
Speakers with integral amplifiers must comply with the requirements in UL 1480
and the Standard for Amplifiers for Fire Protective Signaling Systems, UL 1711.
1.4 Speakers intended for use with emergency and non-emergency systems and
having integral amplifiers must comply with this standard in addition to the require-
ments in the Standard for General-Purpose Signaling Devices and Systems, UL 2017.
1.5 Speakers intended for use in air-handling spaces in accordance with Installa-
tion of Air Conditioning and Ventilating Systems, NFPA 90A, shall comply with the
requirements in this standard and the requirements in the Standard for Fire Test
for Heat and Visible Smoke Release for Discrete Products and Their Accessories
Installed in Air-Handling Spaces, UL 2043.
15B. IEC 60529:
IPX4 Rated
This standard applies to the classification of degrees of protection provided by enclosures
for electrical equipment with a rated voltage not exceeding 72,5 kV.
Object:
The object of this standard is to give:
a) Definitions for degrees of protection provided by enclosures of electrical equipment as
regards:
1) protection of persons against access to hazardous parts inside the enclosure;
2) protection of the equipment inside the enclosure against ingress of solid foreign objects;
3) protection of the equipment inside the enclosure against harmful effects due to the
ingress of water.
b) Designations for these degrees of protection.
c) Requirements for each designation.
d) Tests to be performed to verify that the enclosure meets the requirements of this
standard.
