The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
Up to 6059-1 including second characteristic numeral 6, the designation implies compliance also with the requirements for all lower characteristic numerals. Marking with the IP Code indicates a claim for compliance with all the applicable requirements of this standard and also with any complementary requirements specified in the appropriate product standard.
Tested for harmful effects due to ingress of water when the movable parts of the equipments are in motion.
Additional letters are only used – if the actual protection against access to hazardous parts is higher than that indicated by the first characteristic numeral – or if only the protection against access to hazardous parts is indicated, the first characteristic numeral being then replaced by an X.
As per the IP code identified by the manufacturer, we do the testing to kec the effects of exposure, and give the appropriate IP rating. Product Details For checking the protection against water to prove the degrees of protection with the second number X1. This means that the full diameter of the sphere shall not pass through an opening, in the enclosure.
BS EN +A – Degrees of protection provided by enclosures (IP code)
Such exceptional cases shall conform with the requirements of this, basic safety standard and the product standard shall state clearly the additional procedure to be cafried out during tests for such a classification. Object probes for numerals 3 and 4 shall not penetrate the enclosure at all. Leave a Comment Click here to cancel reply. Product Details High-precision manufactured and is made of Stainless steel.
Measurement data and uncertainty data is available. If it partly or fully penetrates, it is placed in every possible position, but in no case shall the stop face fully penetrate through the opening. The access probe shall not touch hazardous live parts. The suction connection shall be made to a hole specially provided for this test.

Meets Requirements for Testing Standard s including but not limited to: In the last two cases, the volume of air to be drawn through the enclosure under test shall be the same as for the whole enclosure in full scale.
S Empty enclosures If the enclosure is tested without equipment inside, detailed requirements shall be indicated by the enclosure manufacturer in his instructions for the arrangement and spacing of hazardous parts or parts which might be affected by the penetration of foreign objects or water.
Hazardous live parts covered only with varnish or paint, or protected by oxidation or by a similar process, are covered by a metal foil electrically connected to those parts which are normally live in operation.
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. To carry and rotate the specimens when determining the protection against water. The talcum powder used shall be able to pass through a square-meshed sieve the nominal wire diameter of which is 50 jim and the nominal width of a gap between wires 75 jim.
NOTE Enclosures assigned a first characteristic numeral of 1 to 4 generally exclude both regularly and irregularly shaped solid foreign objects provided that three mutually perpendicular dimensions of the object exceed the appropriate figure in column 3 of table 2.
The maximum acceptable radius of the oscillating tube is 1 mm. Premium Membership Premium membership gives you an access to specialized technical articles and extra premium content electrical guides and software.
However, the tests establishing compliance with any one of the lower degrees of 605299-1 need not necessarily be carried out provided that these tests would obviously be met if applied. In the absence of a specification the acceptance conditions of this standard shall at least apply. Manufacturer must ieec consulted to determine the degree of protection. However, it is recommended that for a given classification the tests do not differ from those specified in this standard.
The enclosure under test is supported inside the test chamber and the pressure inside the enclosure is maintained below the surrounding atmospheric pressure by a vacuum pump. Internal moving parts may be operated slowly; where this is possible. If for certain types of apparatus it is not possible to wet all parts of the enclosure under test, the support of the enclosure mayjbejfneved up or down.
However, the tests establishinq compliance with any one of the lower degrees of protection need not ‘necessarily be carried out provided that these 60529-11 obviously would be met if applied. In the case of the test for the additional letter B, the jointed test finger may penetrate to its 80 mm length, but the stop face 0 50 mm x 20 mm shall not pass through the opening.
