This standard gives definitions for standard degrees of protection provided by enclosures applicable to rotating electrical machines as regards the:
a) protection of persons against contacts with or approach to live parts and against contact with moving parts (other than smooth rotating shafts and the like) inside the enclosure and protection of the machine against ingress of solid foreign objects;
b) protection of machines against the harmful effects due to ingress of water.
It gives designations for these protective degrees and tests to be performed to check that the machines meet the requirements of this standard.
The following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
In special applications (such as machines with open circuit cooling for ship deck installation with air inlet and outlet openings closed during standstill),numerals may be followed by a letter indicating whether the protection against harmful effects due to ingress of water was verified or tested for the machine not running (letter S) or the machine running (letter M). In this case, the degree of protection in either state of the machine shall be indicated, for example IP55S/IP20M.
NOTE 1 The brief description given in the second column of this table should not be used to specify the type of protection.
NOTE 2 Machines assigned a first characteristic numeral 1, 2, 3 or 4 will exclude both regularly or irregularly shaped solid objects, provided that three normally perpendicular dimensions of the object exceed the appropriate figure in the Definition’ column.
NOTE 3 The degree of protection against dust defined by this standard is a general one. When the nature of the dust (dimensions of particles, their nature, for instance fibrous particles) is specified, test conditions should be determined by agreement between manufacturer and user.AS 60034.5 pdf free download.
